Hair Loss on GLP-1 (Mounjaro/Wegovy/Ozempic): What Actually Helps (UK)
If you’re on a GLP-1 and noticing more hair shedding than usual, you’re not alone. The frustrating bit? It can happen even when the weight loss is “going well”. The helpful bit? In many cases, this is a temporary shedding phase and the best fixes are boring: protein consistency + hydration + nutrient basics, not a cupboard full of pills.

Not medical advice. Hair loss can have medical causes. If you’re pregnant/breastfeeding, have a medical condition, or take medication (especially thyroid meds, blood thinners, diabetes meds, blood pressure meds), check labels and speak to your GP/pharmacist/clinician. If you have patchy hair loss, scalp pain/itching, sudden severe shedding, or symptoms like persistent fatigue/dizziness, get checked.
Quick answer (snippet-ready): GLP-1 hair shedding is often triggered by rapid weight loss, lower protein intake, and nutrition gaps. Start by locking in protein + fluids, then cover basics with a simple daily routine. If you want targeted support, try one option at a time (e.g., biotin or collagen) for 8–12 weeks. If shedding is extreme or patchy, speak to your GP.

Why hair loss can happen on GLP-1 (even if you’re doing everything “right”)
On GLP-1 meds, you often eat less without trying. That’s the mechanism — but it can also mean your body quietly slides into “low input” mode.
- Rapid weight loss can push hair follicles into a temporary shedding phase (often called “telogen effluvium”).
- Lower protein is common on GLP-1 (because appetite is lower, portions are smaller, and meat can feel heavy).
- Lower fluids often tag along with lower appetite — and dehydration makes everything feel worse.
- Nutrient gaps can creep in when food volume drops for weeks/months.
In my own GLP-1 journey, the biggest improvement came from doing the basics consistently. Not “more supplements” — just less chaos: protein first, hydration first, and a simple baseline so I wasn’t guessing.
The 5-minute “start here” routine (what I’d do before buying anything)
- Protein anchor: aim for a repeatable protein habit you can actually stick to (even if it’s smaller portions).
- Hydration habit: big bottle + reminders. If you’re headachy, crampy, dizzy, or “flat”, don’t ignore fluids.
- Baseline coverage: pick one “daily” routine (not ten separate products).
- One targeted trial: only add one hair/skin support option at a time — and give it long enough to judge.

Best picks (minimal stack): what I’d try first
These are “boring but useful” options you can trial without turning your kitchen into a pharmacy. I’m linking to my hub product pages first (so you can read the notes), then a Lily & Loaf “buy” link second.
1) Biotin Plus (simple hair/skin/nails routine)
Read more: https://alanspicer.com/best-health-supplements/products/biotin-plus.html
Why I’d try it: If you want one simple, consistent “beauty basics” habit without stacking multiple formulas, this is an easy, low-faff trial.

2) Collagen Plus (skin + structure support routine)
Read more: https://alanspicer.com/best-health-supplements/products/collagen-plus.html
Why I’d consider it: Collagen routines are slow-burn. If you’re playing the long game (8–12+ weeks), collagen can be a straightforward, consistent add-on.

3) Hydrolysed Collagen+ 8,700mg (powder format, higher dose style)
Read more: https://alanspicer.com/best-health-supplements/products/hydrolysed-collagen.html
Why I’d consider it: If you prefer a powder routine (and you’ll actually use it daily), this can be easier to stick to than capsules.

4) Collagen + MSM + Vitamin C (beauty + joints style combo)
Read more: https://alanspicer.com/best-health-supplements/products/collagen-msm-vit-c.html
Why I’d consider it: If you want collagen support plus “extras” in one product (instead of stacking separate bits), this is a neat all-in-one style option.

5) Skin, Hair & Nail Gummies (easy adherence if capsules are a struggle)
Read more: https://alanspicer.com/best-health-supplements/products/skin-hair-nail-gummies-60.html
Why I’d consider it: If GLP-1 nausea or food aversion makes capsules feel grim, gummies can be a simple “I’ll actually take it” option.

6) Iron 20mg with Vitamin C (ONLY if you’re low / advised to supplement)
Read more: https://alanspicer.com/best-health-supplements/products/iron-20mg.html
Important: Don’t guess iron. If shedding is significant and you’re also exhausted, dizzy, breathless, or you have heavy periods, get checked. Iron is useful when it’s needed — but it’s not a casual “beauty supplement”.

Money + sanity rule: pick one targeted product, then give it time. Hair routines don’t reward panic-buying.
Comparison table: choose the right option (without stacking everything)
| If your main goal is… | Start with | Why this is a sensible first step | Fair test window | Hub page |
|---|---|---|---|---|
| “I want a simple hair/skin/nails habit” | Biotin Plus | Simple, consistent routine; easy to trial without stacking | 8–12 weeks | Biotin Plus |
| “I want collagen support in capsules” | Collagen Plus | Slow-burn routine for people who’ll take it daily | 8–12+ weeks | Collagen Plus |
| “I prefer powder (easier adherence)” | Hydrolysed Collagen+ | Powder format can be easier than pills if nausea/aversion is an issue | 8–12+ weeks | Hydrolysed Collagen+ |
| “I want collagen + extras in one” | Collagen + MSM + Vitamin C | One-product approach vs stacking multiple support items | 8–12+ weeks | Collagen + MSM + Vitamin C |
| “Capsules are a struggle — I need easy” | Skin, Hair & Nail Gummies | Adherence-first option: the best product is the one you’ll actually take | 8–12 weeks | Skin, Hair & Nail Gummies |
| “I suspect deficiency (fatigue, heavy periods)” | Iron (only if advised) | Iron helps when you’re actually low — don’t guess | Clinician-guided | Iron 20mg |
What NOT to do (trust booster)
- Don’t panic stack 6 products. You won’t know what helped (or what caused side effects).
- Don’t crash diet. Rapid loss + low protein is a common hair-shedding combo.
- Don’t “guess” iron. Too much iron is not a win. Get checked if you suspect it’s relevant.
- Don’t expect a 7-day miracle. Hair routines are measured in months, not days.
- Don’t ignore red flags (patchy loss, scalp pain, severe fatigue, breathlessness).

Timeline: what to expect (3 days / 2 weeks / 30 days / 90 days)
In 3 days: If you were under-drinking or under-eating protein, tightening up basics can make you feel more stable (energy/mood/constipation often improve first — hair won’t).
By 2 weeks: Your routine becomes easier and more repeatable. This is where you’re building the foundation that supports hair long term.
By 30 days: You’ll usually notice you’re less “run down”. Hair changes are still early, but consistency is starting to stack up.
By 90 days: This is the first point many people can judge whether a targeted hair routine is helping. If shedding started after rapid weight loss, this is also the period it often begins to settle — but if it’s getting worse, get checked.
When to speak to a GP/pharmacist/clinician
Book a check-in if any of these apply:
- Patchy hair loss (not general shedding)
- Scalp pain, burning, itching, heavy dandruff, sores
- Sudden extreme shedding or eyebrow/eyelash thinning
- Fatigue + dizziness + breathlessness, or you feel “not right”
- You have known thyroid issues or symptoms suggesting thyroid changes
If your clinician can run basic checks (like iron status, thyroid markers, etc.), it removes guesswork and saves money.

FAQs
1) Can GLP-1 medications cause hair loss?
GLP-1 meds can be linked to hair shedding indirectly because appetite drops and weight loss can be rapid. The common trigger is the overall change (lower intake + faster loss), not the injection itself in isolation.
2) Is hair loss on GLP-1 permanent?
Often it’s temporary shedding, but not always. If it’s patchy, painful, or getting worse over months, get checked for other causes.
3) When does hair shedding usually start?
Many people notice shedding after weeks or months of rapid change. Hair routines are judged in months, not days.
4) What’s the #1 thing to do first?
Make protein and hydration boringly consistent. If you’re under-eating, no supplement will out-perform the basics.
5) Should I take biotin for hair loss?
Biotin can be a simple trial for a hair/skin/nails routine, but it’s not magic. If shedding is due to rapid weight loss, the foundation still matters most.
6) Does collagen help hair regrowth?
Collagen is commonly used as part of a longer-term beauty routine. If you try it, commit to 8–12+ weeks so you can judge it fairly.
7) Are gummies better than capsules on GLP-1?
If nausea or aversion makes capsules hard, gummies can be easier to stick to. Adherence matters more than “perfect” format.
8) Should I take iron for hair loss?
Only if you’re low or advised to. Don’t guess iron — ask your GP for checks if you suspect it’s relevant.
9) What if hair loss is patchy?
Patchy hair loss needs medical advice. That pattern can point to different causes than general shedding.
10) How long should I trial a hair supplement?
Usually 8–12 weeks minimum. If you change three things at once, you won’t know what helped.
11) Can rapid weight loss trigger shedding even with “good” supplements?
Yes. Supplements don’t cancel out low protein intake, dehydration, poor sleep, or very rapid loss.
