If you're losing weight on Ozempic, Wegovy, Mounjaro or Zepbound

Shedding hair on your GLP-1?
It's biology — not bad luck.

Rapid weight loss leaves your hair without the raw material it's built from. This page explains what's happening — and the 90-day plan that gives your follicles what they need to grow back.

Why it's happening

Three things are happening to your hair right now

You're eating half of what you used to

When food runs short, your body sends nutrients to your organs first. Hair gets whatever is left over — and right now, that's not much.

2–5

Months 2–5 are when it shows

Hair roots react to sudden change by letting go of their strand and resting. So the shed shows up months after you start — right as the weight comes off fastest.

Twice the risk on semaglutide

A 2025 study of 3,700 women found hair loss about twice as likely on semaglutide. Researchers point to how fast the weight comes off — not the drug itself.

The good news

Your follicles aren't dying — they're resting

Doctors call this kind of shedding telogen effluvium. In plain English: too many hairs took their rest break at the same time. The root under every hair you've lost is still alive, and within weeks it starts building a new strand. What that strand is made of depends on what you feed it.

Three-stage medical illustration of the hair cycle: a thick growing hair, a hair detaching and shedding, and a follicle resting with new growth beginning

1 · GrowingThe root is fed and building — about 90% of your hair, normally

2 · ReleasingThe strand lets go — this is the hair you see in the drain

3 · RestartingThe root rests, then starts a new strand — built from what you give it

One honest question first

Is this for "regular" hair loss? No — here's why.

✓ Built for weight-loss shedding

Started suddenly — weeks or a few months after rapid weight loss began
All-over thinning — drain, brush, pillow; no bald patches
Usually temporary — follicles paused, not dead, and nutrition-responsive

✗ Not built for pattern hair loss

Gradual, over years — receding line or widening crown, often runs in the family: that's androgenetic alopecia, a hormonal process. It needs a dermatologist's toolkit, not a nutrient stack.
Round bald patches or scalp symptoms — see a dermatologist promptly. That's a different condition and needs proper care.

A simple rule of thumb: if the shedding started suddenly, soon after the weight loss began, that's what Retaine is built for. If it crept in over years, see a specialist instead. Selling you the wrong fix helps no one.

Here's the fix

Retaine: three steps that give your hair back what the diet took away

You just read the three problems — not enough nutrients coming in, roots on pause, new strands growing in thin. The 90-Day Plan answers each one, every day, for one full growth cycle.

Retaine Daily Hair Nutrient Capsules bottle open beside breakfast

Step 1 · Daily capsules

Replace the nutrients you're not eating

Iron, zinc, vitamin D, B12, biotin, selenium — the ones that disappear when your meals shrink. Every dose listed below.

Retaine Collagen Peptide Powder dissolving into a cup of coffee

Step 2 · Collagen in your coffee

Give your hair the protein it's made of

10 g of collagen peptides — the same daily dose used in the clinical studies — stirred into your morning cup. You won't taste it.

Retaine Shed-Phase Scalp Serum dropper bottle on a bathroom counter

Step 3 · Nightly scalp serum

Help the new strands coming in

Peptides and caffeine, applied at the scalp — right where new hair starts. 30 seconds before bed.

What's inside

Everything your hair is missing, covered daily

Hair is built from a short list of nutrients. Here's each one, what a typical day on a GLP-1 actually provides, and how Retaine fills the difference:

In Retaine daily	Why your hair needs it	Your ~1,200 kcal alone	With Retaine
Collagen protein10 g	Builds the strand itself	~35–45 g of the 50–60 g needed	✓ Gap closed
Vitamin D32,000 IU	Keeps follicles in growth mode	~100–200 IU of 600–800 IU	✓ Covered
Iron18 mg	Carries oxygen to the root	~7–9 mg of up to 18 mg	✓ Covered
Zinc15 mg	Runs the growth cycle	~5–7 mg of 8–11 mg	✓ Covered
Vitamin B12500 mcg	Energy for hair-building cells	Often short when meat is skipped	✓ Covered
Biotin5,000 mcg	Feeds keratin production	Varies by diet	✓ Covered
Selenium100 mcg	Supports the cycle, dosed at the safe level	Varies by diet	✓ Covered
Ashwagandha300 mg	Eases the stress of rapid change — a known shed trigger	Not in any diet	✓ Included

"Typical" estimates: national dietary survey averages scaled to a ~1,200-kcal reduced-appetite intake — your diet may differ. Targets reflect general adult recommendations, not a diagnosis. Some capsule doses (like vitamin D and B12) are intentionally higher than the daily target because only a fraction of oral vitamins is absorbed — every dose stays well within established safe upper limits. Talk to your doctor about your individual needs.

Let's be straight with each other

What this does — and what it doesn't

It's not a drug. It's the nutrition your hair stops getting when your appetite is switched off.
The shed usually settles on its own. What Retaine changes is what your regrowth is built from — full supply instead of a shortage.
Nothing visible happens in week one. New hair needs 8–12 weeks to show. Anyone promising faster is selling you a story.
Patchy, severe, or going on past a year? See a dermatologist first — worth ruling out other causes properly.

Talk to your doctor before adding supplements to your routine, especially alongside prescription medication.

Why everything here says 90 days

Hair works on a 90-day clock

A follicle needs 8–12 weeks to rest, restart, and push out a strand you can actually see. The clinical studies measured their results at 12 weeks for exactly that reason. That's why this is a 90-day plan — and why the guarantee covers all 90 days, not the first 30.

8–12

weeks for a follicle to rest, restart and regrow a visible strand

Quick answers

Questions

Is this shedding permanent?

Usually not. Telogen effluvium is a phase shift, not follicle death — it typically resolves as your body adjusts. If it's patchy, severe, or drags on, see a dermatologist to rule out other causes.

When will I notice anything?

Most members report less hair in the brush first — typically weeks 8–12 — then baby hairs along the part line. Anyone promising a visible change in days is lying to you; the biology doesn't allow it.

Can I take it with my medication?

Retaine is a dietary supplement — vitamins, minerals, collagen, and a topical serum. Still, talk to your doctor before adding any supplement alongside a prescription such as semaglutide or tirzepatide. Every dose is on the label.

Why 90 days and not one month?

Because a follicle needs 8–12 weeks to rest, restart and grow a strand you can see — and that's where the clinical studies measured results. A one-month supply runs out before a single new strand has finished growing.

How does the guarantee work?

Use the system for up to 90 days. Not glad you did? Email us and the refund goes back to your card — empty bottles and all, no return shipping, no hoops.

Will it interfere with my weight loss?

No. The capsules and serum add zero calories, and the collagen adds about 35–40 — less than a splash of milk. Nothing in Retaine affects your appetite or how your medication works.

I'm already months into the shedding — is it too late?

No. The roots that shed are resting, not gone, and they restart on their own schedule over several months. Whenever you begin, every strand built from that day on gets built with full supply.
