Worried about Mounjaro hair loss? A UK pharmacist explains why it happens, when it stops, and 13 practical, evidence-based ways to protect your hair while losing weight.
Mounjaro hair loss is one of the most common concerns I hear about in clinic, and if you’ve noticed more strands in your hairbrush or shower drain since starting your weight loss journey, you’re certainly not imagining it. As a pharmacist working with patients on weight loss medication every week, I can tell you two things straight away: yes, hair shedding on Mounjaro is real, and no, it almost never means what people fear it means.
The panic usually starts around month three or four. The weight is coming off beautifully, energy is improving, clothes are fitting differently — and then suddenly the shower drain tells a different story. Patients arrive convinced the medication is “poisoning” their hair follicles, or that they’ll have to choose between their weight loss and their hair.
Neither of those things is true. But there’s a lot of confusion out there, plenty of half-truths circulating on TikTok and Facebook groups, and an entire industry of expensive supplements ready to take advantage of your worry. So let’s cut through all of it. In this article, I’ll explain exactly what’s happening to your hair on Mounjaro, what the clinical evidence actually shows, how long it lasts, and — most importantly — 13 practical things you can do to reduce shedding and support healthy regrowth.
Grab a cup of tea. This is a long read, but by the end of it you’ll understand your hair better than most people ever do.
Before We Get to Mounjaro Hair Loss: What Is Mounjaro and How Does It Work?
Mounjaro is the brand name for tirzepatide, a once-weekly injectable medication originally developed for type 2 diabetes and now widely prescribed for weight management. It belongs to a newer generation of medicines that work on your body’s own appetite and blood sugar hormones.
What makes tirzepatide different from older medications like Ozempic or Wegovy (both semaglutide) is that it works on two hormone receptors rather than one. It mimics both GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide). In plain English, that means it:
- Slows down how quickly your stomach empties, so you feel fuller for longer
- Reduces appetite signals in the brain, quieting the constant “food noise” many people describe
- Improves how your body handles insulin and blood sugar
The result, for most people, is a significant reduction in how much they eat — and substantial weight loss. In the major clinical trials, participants on the higher doses lost around 20% of their body weight on average over 72 weeks. That’s a level of weight loss we previously only saw with bariatric surgery.
And here’s the crucial point for our topic today: it’s that speed and scale of weight loss — not the drug itself — that sits at the heart of the hair loss story.
Is Mounjaro Hair Loss Real? The Honest Answer
Let’s look at what the evidence says, because this is where a lot of online discussion goes wrong.
In the SURMOUNT-1 clinical trial (the big study that led to tirzepatide’s approval for weight loss), hair loss — recorded as “alopecia” — was reported by roughly 5% of participants taking tirzepatide, compared with around 1% of those taking a placebo. So yes, hair shedding was reported more often in people taking the medication. That’s not in dispute.
But here’s the part that matters: the pattern, timing, and character of that hair loss point overwhelmingly to something called telogen effluvium — a temporary, reversible type of shedding triggered by the rapid weight loss itself, not by tirzepatide attacking your hair follicles.
We know this for several reasons:
The same thing happens with every method of rapid weight loss. Hair shedding is well documented after bariatric surgery, very low-calorie diets, and crash dieting — none of which involve tirzepatide. Studies of gastric sleeve and bypass patients report temporary hair loss in anywhere from 30% to 50% of cases in the first year. Rapid weight loss sheds hair, full stop, regardless of how you achieve it.
Tirzepatide has no known direct mechanism for damaging hair follicles. It works on gut hormones and appetite centres in the brain. It is not a chemotherapy agent, it doesn’t interfere with hormones like testosterone or oestrogen in a way that affects hair, and it doesn’t attack rapidly dividing cells.
The shedding follows the classic telogen effluvium timeline. It typically begins two to four months after weight loss starts, comes on diffusely across the whole scalp rather than in patches or a receding pattern, and settles once weight stabilises.
So the honest, accurate answer is this: Mounjaro doesn’t cause hair loss directly — but the rapid weight loss and reduced food intake it produces very much can. It’s a subtle distinction, but it changes everything about how you deal with it. You’re not fighting the medication. You’re supporting your body through a demanding transition.
The Hair Growth Cycle: The Key to Understanding Mounjaro Hair Loss
To understand why the shedding happens — and why it stops — you need to know a little about how hair actually grows. Bear with me, because once this clicks, the whole thing stops being frightening.
Every hair on your head is on its own independent life cycle, moving through three phases:
Anagen (the growing phase). This is the active phase, lasting anywhere from two to seven years. At any given moment, around 85–90% of your hairs are in anagen, steadily growing about a centimetre a month.
Catagen (the transition phase). A brief two-to-three week phase where the follicle shrinks and detaches from its blood supply.
Telogen (the resting phase). The hair sits dormant in the follicle for around three months, then falls out to make way for a new hair growing underneath. Normally about 10–15% of your hairs are in telogen at any one time, which is why shedding 50–100 hairs a day is completely normal.
Now, here’s where weight loss comes in. Your hair is, biologically speaking, a luxury. It’s not essential for survival. So when your body detects a sudden, significant drop in energy intake — which is exactly what happens when Mounjaro switches off your appetite — it makes an executive decision: divert resources away from non-essential projects and protect the vital organs.
The result is that a much larger proportion of your hairs — sometimes 30% or more instead of the usual 10–15% — get abruptly pushed out of the growing phase and into the resting phase. This is telogen effluvium, which literally means “an outflow of resting hairs.”
Because telogen lasts about three months, there’s a built-in delay. The trigger happens (rapid calorie reduction and weight loss begins), and then two to four months later, all those hairs that entered telogen at the same time start falling out together. That’s why the shedding often seems to come out of nowhere, right when you’re feeling great about your progress.
The critical thing to understand — and I really want this to sink in — is that the follicles are not dead, damaged, or destroyed. Every single one of those shed hairs is being replaced by a new hair already growing beneath it. Telogen effluvium is a synchronisation problem, not a destruction problem. Your hair density looks thinner temporarily because so many hairs left at once, but the factory is still fully operational.
When Does Mounjaro Hair Loss Start — and When Does It Stop?
Based on what we see in practice and what the research on rapid weight loss tells us, the typical timeline looks like this:
Months 1–2 on Mounjaro: Usually nothing. Weight loss begins, appetite drops significantly. The trigger is being pulled, but the hair effects haven’t surfaced yet.
Months 3–5: Shedding typically becomes noticeable. More hairs on the pillow, in the brush, in the shower. This is often when the panic sets in. Overall thinning may become visible, particularly around the temples and parting, simply because that’s where thinning shows first.
Months 6–9: For most people, shedding begins to slow, especially if weight loss has started to plateau or the rate of loss has gentled. The body recalibrates.
Months 9–18: Regrowth becomes visible. You may notice fine, short “baby hairs” around the hairline and parting — these are the new anagen hairs coming through. Full cosmetic recovery of density can take 12–18 months because hair only grows about a centimetre a month.
A few important caveats. If your weight loss continues aggressively for a long period, the shedding phase can be prolonged, because the trigger is still active. And if you have an underlying deficiency (iron is the big one) or another condition like thyroid disease, the shedding can be heavier and slower to resolve. That’s why the tips below matter so much — you can’t skip the biology, but you absolutely can influence how severe it gets and how quickly it recovers.
Who Is More Likely to Experience Mounjaro Hair Loss?
Not everyone sheds. In fact, most people don’t — remember, it was reported by roughly 1 in 20 trial participants, though real-world numbers among people losing weight quickly are probably somewhat higher. Certain factors do increase your risk:
Being female. Interestingly, women report hair loss on tirzepatide far more often than men. This likely reflects a combination of longer hairstyles making shedding more visible, hormonal factors, and lower baseline iron stores (menstruation is a major cause of low ferritin in women).
Rapid or large total weight loss. The faster and greater the loss, the bigger the metabolic “shock” signal to the follicles.
Low protein intake. Hair is made almost entirely of keratin, a protein. When appetite is suppressed and portions shrink dramatically, protein is often the first thing to fall short.
Pre-existing low iron, vitamin D, zinc, or B12. Marginal stores that were “just about coping” before can tip into functional deficiency once intake drops.
Thyroid conditions. An underactive or overactive thyroid independently causes hair changes and can compound weight-loss shedding.
Recent pregnancy, menopause, major illness, surgery or high stress. All of these are independent telogen effluvium triggers. Stack them on top of rapid weight loss and the effect multiplies.
A family history of pattern hair loss. Telogen effluvium can sometimes “unmask” or accelerate underlying androgenetic (genetic) thinning that was going to develop anyway. This is one situation where proper assessment matters, and I’ll come back to it.
13 Tips to Stop Mounjaro Hair Loss (What Actually Works)
Now for the part you came here for. These are the strategies I discuss with patients week in, week out — ranked roughly in order of impact. Notice that the most powerful ones are free, and none of them require you to stop your medication.
1. Slow down the rate of weight loss — the single best way to stop Mounjaro hair loss
This is the single most effective lever you have, because it addresses the root cause rather than the symptom. The follicle “shock” is proportional to how fast the energy deficit hits. Someone losing 0.5–1kg a week generally sheds far less than someone dropping 2kg or more week after week.
Mounjaro doses are meant to be increased gradually — 2.5mg, 5mg, 7.5mg and so on — and there is no rule that says you must climb the ladder as fast as possible. If your weight loss is aggressive and your shedding is significant, it’s completely reasonable to stay on your current dose for longer rather than escalating. Some prescribers will even space injections slightly or hold a dose increase while things settle.
Please don’t adjust anything yourself — this is a conversation to have with whoever prescribes your Mounjaro. But have the conversation. In my experience, most patients are never told that slower can be better, and many assume more medication always equals better results. For your hair (and your skin, and your muscle mass), a steadier pace wins.
2. Protect your protein — the nutritional foundation against Mounjaro hair loss
Hair is about 95% keratin — pure protein. When your appetite disappears on Mounjaro, protein intake often collapses without you noticing, because you’re simply eating much less of everything. Your body then triages: available protein goes to muscles, organs and immune function first, and hair gets whatever’s left. Often, that’s nothing.
Aim for roughly 1.2–1.5g of protein per kilogram of body weight per day while losing weight — for most people that’s somewhere between 80 and 120g daily. When your stomach only has room for a small meal, make protein the first thing on the fork: eggs, chicken, fish, Greek yoghurt, cottage cheese, lentils, tofu. Protein shakes are genuinely useful here — not as a gimmick, but because getting 25g of protein from a drink is far easier than forcing down a chicken breast when you have zero appetite.
A practical trick I give patients: eat your protein before anything else on the plate. On Mounjaro you fill up fast, so whatever you eat first is what your body actually receives.
3. Get a proper blood test before spending a penny on Mounjaro hair loss supplements
If you do only one “medical” thing from this list, make it this. Ask your GP or a private provider to check:
- Ferritin (your iron stores — for hair health you generally want this comfortably above 40–50 µg/L, not just “within range”)
- Vitamin D
- Vitamin B12 and folate
- Zinc (if available)
- Thyroid function (TSH)
Iron deficiency is the most common nutritional cause of hair shedding I see, particularly in women, and it’s spectacularly common in people eating much less food. The kicker is that ferritin can be “normal” on paper but suboptimal for hair — a ferritin of 15 might not earn you a deficiency diagnosis, but your follicles will absolutely feel it.
Testing first means you treat what’s actually wrong, at the correct dose, instead of throwing £40-a-month “hair gummies” at a problem they can’t fix. It also catches thyroid issues, which masquerade as weight-loss shedding surprisingly often.
4. Don’t stack a crash diet on top of the medication — it makes Mounjaro hair loss worse
I see this constantly and it breaks my heart a little. Someone starts Mounjaro, gets excited by the early results, and decides to “maximise” progress by also doing intermittent fasting, cutting carbs to nothing, and living on 800 calories a day.
Mounjaro already creates a substantial calorie deficit by switching off your appetite. Adding aggressive restriction on top doesn’t just accelerate hair loss — it accelerates muscle loss, fatigue, nutrient deficiency and, ironically, makes long-term weight maintenance harder because you lose the very muscle tissue that keeps your metabolism ticking.
Eat regular, small, nutrient-dense meals even when you’re not hungry. Yes, even when you’re not hungry — on this medication, hunger is no longer a reliable signal that your body has what it needs. Think of eating on Mounjaro less like responding to appetite and more like scheduled refuelling.
5. Supplement strategically for Mounjaro hair loss — not scattergun
Once you have blood results, supplement what’s actually low:
- Iron — only if ferritin is low, and ideally with vitamin C to aid absorption. Don’t take iron “just in case”; excess iron is genuinely harmful.
- Vitamin D — a large proportion of UK adults are insufficient, especially between October and April. 1,000–2,000 IU daily is a sensible maintenance dose for most; higher if you’re deficient.
- Zinc — involved in follicle function and keratin production. Deficiency is plausible on a very reduced diet.
- B12 — particularly relevant if you’re plant-based or on metformin alongside Mounjaro.
A word on biotin, since every hair supplement shouts about it: true biotin deficiency is rare, and evidence that biotin helps hair in people who aren’t deficient is weak. It’s also worth knowing that high-dose biotin can interfere with blood tests, including thyroid and cardiac markers — so if you take it, tell whoever’s doing your bloods, and stop it a few days before testing.
A good-quality general multivitamin is a reasonable safety net while your food volume is low. Beyond that, save your money.
6. Handle your hair like silk during the Mounjaro hair loss phase
You cannot stop telogen hairs from falling — they were always going to fall — but you can avoid adding mechanical damage and breakage on top of the biological shedding.
While you’re in the shedding phase: skip tight ponytails, buns and braids that put constant tension on follicles (traction is a real, preventable cause of loss). Turn the heat down or off — air dry when you can, and use a heat protectant when you can’t. Swap harsh chemical processes like bleaching and relaxing for gentler options, or postpone them for a few months. Use a wide-tooth comb on wet hair rather than a brush, because wet hair stretches and snaps easily. A silk or satin pillowcase reduces overnight friction — not a miracle, but a marginal gain that costs a tenner.
None of this regrows hair. What it does is preserve every strand you have while the cycle resets, which makes a visible difference to how thick your hair looks during the recovery window.
7. Keep your scalp healthy — but don’t fall for Mounjaro hair loss “miracle” shampoos
Let me save you some money: no shampoo can stop telogen effluvium, because shedding is decided at the follicle root months before the hair falls, not in the shower. Any product promising to “stop hair fall” from a bottle is marketing, not medicine.
That said, a healthy scalp environment does support optimal regrowth. Wash regularly (leaving hair unwashed does not reduce shedding — those hairs are already detached and will fall whether you wash or not, just in a more alarming clump). Treat dandruff or seborrhoeic dermatitis if you have it, since scalp inflammation genuinely can worsen shedding — a ketoconazole shampoo like Nizoral used once or twice weekly is a pharmacist-approved option here. Gentle scalp massage may modestly improve local blood flow, and at worst it’s relaxing and free.
8. Consider topical minoxidil if Mounjaro hair loss is heavy or prolonged
If your shedding is severe, dragging on beyond six to nine months, or you’re particularly distressed by it, topical minoxidil (Regaine and generic versions, available from pharmacies without prescription) is the one over-the-counter treatment with solid evidence behind it.
Minoxidil works by prolonging the anagen growing phase and nudging resting follicles back into growth sooner. It’s used for pattern hair loss primarily, but dermatologists frequently use it to speed recovery in stubborn telogen effluvium too.
Two honest warnings from your pharmacist. First, minoxidil often causes a temporary increase in shedding in the first four to eight weeks — this is old resting hairs being pushed out by new growth, and it means it’s working, but nobody enjoys it. Second, it requires commitment: results take four to six months, and stopping means gradually losing what it gained. Some clinicians also prescribe low-dose oral minoxidil off-label for suitable patients — that’s a conversation for a doctor or hair specialist, not a DIY project.
9. Sleep, stress and the Mounjaro hair loss spiral
Here’s a cruel bit of biology: stress is itself a trigger for telogen effluvium. Which means that lying awake at 2am panicking about your hair falling out can, quite literally, make more of your hair fall out. I’ve watched patients get trapped in exactly this loop.
Cortisol, your main stress hormone, pushes follicles toward the resting phase and disrupts the nutrient supply to the scalp. Poor sleep amplifies cortisol. So the boring advice — seven to eight hours of sleep, regular movement, whatever genuinely de-stresses you, whether that’s walking, prayer, gym, or getting off the Facebook groups where everyone catastrophises about side effects — is legitimate hair advice.
If it helps, reframe the shedding every time you see it: those hairs were already dead months ago, and each one has a replacement growing underneath it right now. That’s not wishful thinking; it’s literally how the follicle works.
10. Hydration, healthy fats and the forgotten micronutrients
Beyond protein, a few dietary details punch above their weight for hair:
Omega-3 fatty acids support scalp health and have anti-inflammatory effects — oily fish twice a week (salmon, mackerel, sardines) or a fish oil/algae supplement if you don’t eat fish.
Iron-rich foods even if you’re supplementing: red meat, lentils, spinach, fortified cereals. Pair plant sources with vitamin C (peppers, citrus) and avoid taking iron with tea or coffee, which block absorption — a genuinely underrated tip.
Water. Mounjaro’s appetite suppression often suppresses thirst cues too, and mild chronic dehydration is common on these medications. It won’t cause hair loss on its own, but it does nothing good for hair, skin, energy or the constipation that many Mounjaro users battle. Aim for 2 litres a day; set reminders if you have to.
11. Don’t stop Mounjaro abruptly out of hair loss panic
Some people get so frightened by the shedding that they quit the medication cold turkey — and I’d gently push back on that for several reasons.
First, the hairs currently falling entered their resting phase two to three months ago. Stopping today changes nothing about the next eight to twelve weeks of shedding; that train has already left the station. Second, abrupt discontinuation often leads to rapid appetite return and weight regain, and here’s the truly frustrating part — significant weight regain is itself a metabolic stressor that can trigger a second round of telogen effluvium. I have genuinely seen people shed once on the way down and again on the way back up.
If the hair loss is intolerable for you, that’s a valid feeling and a valid reason to review your treatment — but do it as a planned conversation with your prescriber about dose reduction or a managed pause, not a panic decision on a Tuesday night.
12. Rule out the impostors: conditions that mimic Mounjaro hair loss
Not every hair problem that starts while you’re on Mounjaro is because of Mounjaro. Timing creates a convincing illusion of cause. Before you attribute everything to the injection, make sure someone has considered:
- Thyroid disease — extremely common, especially in women, and a classic cause of diffuse shedding
- Androgenetic (pattern) hair loss — gradual thinning at the crown or temples, often with a family history; rapid weight loss can unmask it early
- Menopause and perimenopause — falling oestrogen changes the hair cycle, and the age groups overlap heavily with Mounjaro users
- Other medications — certain blood pressure tablets, antidepressants, retinoids and anticoagulants can all contribute
- Autoimmune causes — patchy, circular bald spots suggest alopecia areata, which is a different condition entirely and needs medical review
The pattern matters diagnostically: telogen effluvium is diffuse, all-over shedding. Patchy loss, scarring, itching, or a steadily widening parting over years each point somewhere else. If your picture doesn’t fit the classic story, get assessed properly rather than waiting it out.
13. Be patient, track honestly — and consider professional treatments to speed up Mounjaro hair loss recovery
Finally: give the process time, and measure it properly. Take a photo of your parting and hairline once a month under the same lighting. Memory is a terrible judge of hair density, and monthly photos will show you the recovery long before the mirror convinces you. Watch for the tell-tale sign of regrowth — a fringe of short, fine baby hairs standing upright along your hairline around months six to twelve. Patients often mistake these for breakage; they’re actually the comeback.
If shedding has settled but you want to actively accelerate regrowth and density, this is where professional treatments earn their place. PRP and i-PRF (platelet-rich fibrin) therapy — where your own platelets and growth factors are injected into the scalp — has growing evidence for stimulating follicles and improving density, and works particularly well on telogen effluvium recovery because the follicles are healthy and simply need encouragement. Polynucleotide scalp treatments and microneedling are further options a good practitioner can discuss with you. These aren’t necessary for everyone — most people recover fully with time and the basics above — but for those who want to shorten the journey or whose confidence has taken a real knock, they’re legitimate, evidence-informed tools rather than gimmicks.
Whatever route you choose, choose it with a qualified medical professional who examines your scalp, reviews your bloods and gives you honest expectations — not a package sold to you before anyone has asked a single question about your health.
Mounjaro Hair Loss vs Other Weight Loss Injections — Is Mounjaro Worse?
A question I’m asked almost weekly: “Should I switch to Wegovy/Ozempic instead? Is Mounjaro worse for hair?”
The short answer is no — this is a class-wide phenomenon, and it tracks with weight loss, not with the specific molecule. Hair shedding is reported with semaglutide (Wegovy, Ozempic), liraglutide (Saxenda) and tirzepatide (Mounjaro) alike. In the semaglutide weight loss trials, alopecia was reported at broadly similar low single-digit rates.
If anything, because tirzepatide tends to produce greater average weight loss than semaglutide, people on Mounjaro sometimes experience more noticeable shedding — but that’s the weight loss speaking, not some unique property of the drug. Switching medications to escape hair shedding usually just resets the clock while keeping the same underlying trigger. If shedding is your main concern, adjusting the pace of weight loss (tip 1) achieves far more than swapping one injection for another.
The Regain Trap: Why Yo-Yo Dieting Is Worse Than Mounjaro Hair Loss Itself
This deserves its own short section, because it’s the piece almost nobody talks about.
Telogen effluvium is triggered by metabolic stress — and your follicles can’t tell the difference between the stress of losing 15kg and the stress of regaining it. People who cycle repeatedly through loss and regain expose their hair to trigger after trigger after trigger, and over years this pattern of chronic, repeated shedding does more cumulative cosmetic damage than a single, well-managed course of weight loss ever will.
This is one more argument for doing this properly: sensible pace, adequate protein, corrected deficiencies, and a long-term maintenance plan agreed with your prescriber rather than an abrupt stop. Your hair, oddly enough, is one of the best advocates for sustainable weight loss you’ll ever meet.
Mounjaro Hair Loss: When to Seek Medical Advice
Most Mounjaro-related shedding is benign and self-limiting, but please do get properly assessed if:
- Shedding continues heavily beyond nine to twelve months, or starts after your weight has been stable for months
- You notice patchy, circular bald areas, scarring, redness, pain or intense itching of the scalp
- Hair loss comes with other symptoms — exhaustion, feeling cold all the time, palpitations, brittle nails, heavy periods — which can point to thyroid disease or significant iron deficiency
- You’re losing eyebrows, eyelashes or body hair, which is not typical of telogen effluvium
- The pattern looks like classic pattern baldness (widening parting, receding temples, thinning crown) — earlier treatment means better results for androgenetic loss
Your pharmacist is a genuinely good first port of call — we can review your medications, advise on minoxidil suitability and flag when a GP or dermatology referral is warranted. And it costs nothing to ask.
Frequently Asked Questions About Mounjaro Hair Loss
Will my hair grow back after Mounjaro hair loss? In telogen effluvium — which accounts for the overwhelming majority of cases — yes, fully. The follicles are healthy and every shed hair is replaced. Visible recovery typically takes 6–12 months after the shedding settles, because hair grows around 1cm per month.
How common is hair loss on Mounjaro? Around 5% of participants reported it in the main clinical trial, versus about 1% on placebo. Real-world rates among people losing weight rapidly are likely somewhat higher, but it still affects a minority of users.
Does hair loss mean Mounjaro is damaging my body? No. It’s a sign your body is redirecting resources during rapid weight loss — a normal, well-documented adaptation seen with every form of fast weight loss, including bariatric surgery.
Should I stop taking Mounjaro if my hair is falling out? Not abruptly, and not without speaking to your prescriber. The current shedding was triggered months ago and will continue briefly regardless, while sudden weight regain can trigger a fresh round of shedding. Discuss slowing your dose escalation instead.
Do biotin gummies stop Mounjaro hair loss? Almost certainly not, unless you’re genuinely biotin deficient (rare). Protein, iron status, vitamin D and pacing your weight loss matter far more. High-dose biotin can also distort blood test results, so mention it before any bloods.
When does the shedding stop? Usually within three to six months of your weight stabilising or the rate of loss slowing. If it persists well beyond that, get assessed for other causes.
Can PRP or i-PRF help hair loss from weight loss injections? It can be a useful accelerator for regrowth once heavy shedding settles, because the follicles are intact and responsive. It’s an option worth discussing with a medical practitioner, alongside the fundamentals of nutrition and pacing — not a replacement for them.
The Bottom Line on Mounjaro Hair Loss
Here’s everything above, distilled.
Mounjaro hair loss is real, but it’s rarely what people fear. In almost all cases it’s telogen effluvium — a temporary, reversible shedding triggered by rapid weight loss and reduced nutrition, not by the medication attacking your follicles. It typically appears two to four months in, peaks, and then resolves as your weight stabilises, with full regrowth over the following year.
You are not powerless while it happens. Slow the pace of loss with your prescriber, protect your protein intake fiercely, test and correct your iron, vitamin D and thyroid, treat your hair gently, manage stress and sleep, and reach for evidence-based options like minoxidil — or professional treatments like i-PRF — if you want extra support. And whatever you do, don’t let panic push you into quitting a medication that’s transforming your health, or into the crash-diet and regain cycle that’s genuinely far worse for your hair.
Your hair took a temporary hit so your body could do something remarkable. Give it the nutrients, the patience and the gentle handling it needs, and it will come back — usually just in time for you to enjoy it alongside everything else you’ve gained.
