45,000+ Women on GLP-1s Reporting Results

Nobody warned you that GLP-1s would do this to your hair. A trichologist explains why it keeps getting worse.

I need to tell you something…

I say it every week. Different women, same story.

A patient came in last month. Michelle, 46, on Wegovy for 14 months, down 41 pounds. Four months into her medication the shedding started.

Her doctor told her it was normal — a temporary response to rapid weight loss — and to keep her protein up, take her biotin, and give it six months.

So she did. Month five the shedding slowed and she thought she was through it. She waited for the fullness to come back.

It never did. Month seven, still flat. Month nine, still thin. Month eleven, her part was still twice as wide as before and she could still see her scalp under certain lights.

"Did I do something wrong?" she asked me.

She had not. Her doctor was not wrong either. The advice just did not cover the full picture of what was happening — and that gap cost her almost a year.

Here is what nobody explains to women on GLP-1s.

Two completely separate things are happening to your hair at the same time. Most doctors are only addressing one.

Tap each card to see what's happening at the follicle.

PROBLEM 1

TAP TO FLIP

Telogen Effluvium

Rapid weight loss stresses the body. A large number of hair follicles go into a resting phase at the same time, and a few months later they all shed together. This is the terrifying drain-clogging phase. The good news: it is temporary and resolves on its own. Your doctor was right about that.

PROBLEM 2

TAP TO FLIP

DHT Follicle Damage

At the same time, a hormone called DHT is slowly shrinking your follicles from the inside. This has no visible symptoms on its own. It just quietly keeps happening in the background — and nobody in the standard wait-it-out protocol is doing anything about it.

While Michelle was patiently waiting for the telogen effluvium to pass, DHT had been shrinking her follicles the entire time. So when those follicles eventually tried to grow new hair, they were smaller than they were before she started Wegovy. That is why the regrowth came back thin and flat. The follicle doing the growing had gotten smaller.

Why GLP-1 medications specifically make this worse.

Here is the part that almost nobody explains.

Think of estrogen as a security guard standing at the door of every hair follicle on your scalp.

Its job is to keep DHT out. When estrogen is high it does that job well, which is why most women do not deal with significant hair loss when they are younger.

When you lose fat quickly on a GLP-1 medication, your estrogen drops with the fat.

Fat cells store estrogen. When the fat goes, so does a chunk of your estrogen. The security guard disappears. DHT walks straight in and starts doing damage it could not do before.

Once DHT gets in it starts shrinking the follicle. The hair that grows from a shrunken follicle comes back thinner and shorter. If nothing stops DHT, the follicle eventually stops producing visible hair at all

DHT does not stop when the telogen effluvium resolves.

DHT does not stop when you hit your protein goals.

DHT does not stop when your bloodwork comes back normal.

DHT stops when something specifically targets and blocks it.

She had tried every method out there.

Biotin, collagen, and protein are not bad. They support hair growth in general. The problem is that none of them have any effect on DHT. Taking them while DHT is shrinking your follicles is like trying to fill a bath with the drain still open. The water goes in, but nothing actually fills up..

WHAT SHE TRIED

Biotin

Protein

Collagen

Nutrafol

Minoxidil

Waiting it out

WHAT IT ACTUALLY DOES

Supports keratin in existing hair. Zero effect on DHT.

Prevents shedding from protein deficiency only. GLP-1 hair loss is hormonal, not a protein problem.

Helps with hair structure generally. Does not interact with DHT at all.

General hair support supplement. Not built for women losing weight rapidly on GLP-1 medication.

Increases blood flow to the scalp. Requires daily use forever; stop using it and the hair falls out worse than before.

Correct for telogen effluvium. Does nothing for DHT, which kept working the entire time she waited.

Two ingredients actually block DHT. You need both.

There are two natural ingredients studied specifically for blocking DHT. They work in completely different ways — which is why you need both.

Pumpkin Seed Oil

STOPS NEW DHT FROM BEING MADE.

Blocks the enzyme that converts testosterone into DHT in the first place. Less of that enzyme means your body makes less new DHT. A peer-reviewed clinical trial found it increased hair count by up to 40% over 24 weeks.

Saw Palmetto

Stops existing DHT from reaching your follicles.

Blocks the DHT already in your body from attaching to your follicle receptors. Where pumpkin seed oil handles new DHT, saw palmetto handles the DHT that is already there.

Together they cover both sides of the problem in a way that neither one alone can.

The cheaper alternatives are not going to give you the results you expect.

Most pumpkin seed oil capsules on Amazon are raw seed powder, not a cold-pressed extract. To get a therapeutic dose from those you would need to eat about two pounds of raw pumpkin seeds every single day.

And most saw palmetto supplements were made for men with prostate issues. Wrong dose, wrong extraction method, never designed for a woman on a GLP-1 medication losing estrogen along with body fat.

So you take both for a few months, nothing happens, and you conclude the approach does not work. It does work. The product just has to be built correctly for the job.

Bloom & Bond is the only formula I have found that gets both right.

2,000mg

Cold-pressed pumpkin seed oil extract

200mg

Saw palmetto, clinical dose for women

4.7/5

From 1,168+ verified reviews

Formulated specifically for women dealing with hormonal hair loss. Not a general wellness product. Not a men's formula in different packaging. No biotin filler. No collagen. Just the two things your follicles actually need, at the right dose.

Michelle came back six weeks later.

She did not show me photos this time. She just pulled her hair back while she was still standing in the doorway, looked at me, and smiled.

"It is different. I can feel it. Not fully back, but moving in the right direction for the first time in almost a year."

That is all I am trying to get at that stage. Not a transformation in six weeks. Just the follicles finally moving forward instead of continuing to shrink.

If your hair has not come back the way you expected, this is why.

The telogen effluvium resolved and the shedding slowed, but DHT did not stop when the shedding did. Your follicles have been trying to grow back this whole time — just through a smaller opening than before because of the damage that accumulated while you waited.

Blocking DHT now stops that from continuing and gives your follicles the conditions they need to actually recover. The sooner it starts, the more follicles are still in a position to respond.

You don't have to choose between your GLP-1 and your hair.
