GLP-1 & your hair
GLP-1 Hair Loss on Reddit: What Women Try Most, Ranked by the Label
On the shot or about to start? Protein, biotin, collagen, minoxidil and one softgel, checked label by label.
- Women on Reddit try 4 things most. Protein, biotin, collagen and minoxidil, a medicine you put on your scalp.
- Most of the hair loss is shedding, hair falling out all over your head. It often starts around month 3. It settles once your weight holds steady.
- Thinning on top is different. It comes from DHT, a hormone that shrinks the roots on top. None of those 4 slows DHT. The softgel ranked first does.
On Reddit, women on a GLP-1 mostly try four things: protein, biotin, collagen and minoxidil. Most of the hair they lose is shedding, and it settles once the weight holds steady.
Thinning on top is different. None of the four slows DHT, the hormone behind it. The softgel ranked first does.
It's late, and you're on your fourth thread about hair in the drain. Someone always says protein. Someone always says minoxidil.
Not on the shot yet? Then you have time. The shedding usually starts around month 3 or later.
We went through 3,800 posts and comments from women losing hair on the shot. Four things came up again and again.
We checked all four on the same five things. Then we added the one that got all five right.
Why it happensWhat's going on
Two things can happen to your hair. The first is shedding, hair falling out all over your head. It settles by itself.
The second is thinning on top. That one doesn't settle by itself.
Your body makes two hormones that matter for the hair on top. Estrogen is one. Every woman makes it, and one of its jobs is guarding the hair roots.
The other is DHT. Your body makes it from testosterone. Women make a little of that too. DHT shrinks the hair roots on top, so each new hair comes in thinner.
The two pull against each other. While estrogen is up, DHT loses. When estrogen drops, DHT wins on top.
On a GLP-1, that happens in three steps.
- 1Estrogen guards the top
It keeps DHT away from the roots on top.
- 2The shot takes fat fast
Part of your estrogen is made in fat, so it drops too.
- 3The top thins, the back doesn't
DHT reaches the roots on top, and each new hair grows in thinner.
In the threadsHow you got here
On the shot, it usually goes like this. The weight comes off, and a few months later the drain fills up.
So you go to Reddit. You post a photo of the part in your hair, or scroll through ten just like it.
The advice comes fast. Eat more protein. Take biotin. Try minoxidil. Put collagen in your coffee.
All I do is eat protein and I’m still losing hair.
A woman on the shot, on Reddit
Plenty of women try three or four at once. Then they post again and ask what else to try.
That's not a mistake you made. Most of that advice is for the shedding.
Very little of it does anything about DHT.
The checksThe 5 things that matter
Most advice on Reddit feeds the hair. Guarding the roots from DHT is a different job.
Scientists have studied two plants for slowing DHT. Pumpkin seed oil is pressed from pumpkin seeds. Saw palmetto is the berry of a small palm tree.
Five things to look for
Here's what to look for on the label.
- Made for women. It says women on the front.
- Slows DHT. It has pumpkin seed oil and saw palmetto, with the amounts.
- Clear, easy dose. Every amount is printed. No “blend” that hides how much. Nothing to rub on your scalp every day.
- Blood tests. Low biotin and no iodine, so your blood tests stay accurate.
- 12 weeks. Hair takes that long to show a change. Twelve weeks should cost about $60 or less.
We checked every product below on these same five things.

"It all grew back once my weight stabilized and I started eating more protein"
A woman on the shot, on RedditVerdict. Protein helps protect your muscle while the weight comes off, so keep it up. But it does nothing about DHT, which thins the top.

Two softgels a day. Here is everything in them, and how much.
| Ingredient | Per day | What it does |
|---|---|---|
| Pumpkin seed oil, cold-pressed | 1,000 mg | Slows the switch at the root that makes DHT |
| Saw palmetto extract | 320 mg | Slows the same switch, a second way |
| Zinc | 10 mg | A mineral hair roots use to grow |

Every dose is printed on the label. No blend.
How it works
Estrogen helps guard the top from DHT. On the shot, estrogen drops along with the fat.
Women make a little testosterone too. At the root, a natural switch called an enzyme turns some of it into DHT.
Both plants slow that switch, right at the root. So less DHT gets made.
Each plant does this in its own way. No prescription needed.
Where it comes from
Pumpkin seed oil is pressed cold from the seeds, like a good olive oil. Saw palmetto is the berry of a small palm tree that grows wild in Florida.
What the research says
There's one small study, in men. They took 400 mg of pumpkin seed oil a day for 24 weeks.
At the end, their hair count was up about 40%. There's no study in women.
Number one has 1,000 mg of the oil in every daily dose.
What makes it different
No other product here has 1,000 mg of cold-pressed pumpkin seed oil. It adds 320 mg of saw palmetto and keeps biotin low.
It's made for women losing hair on top, on the shot or about to start. No iodine, so your blood tests stay accurate.

What women on Reddit ask most
Is Reddit right that it's just shedding?
Mostly, the threads are right. The shedding usually settles a few months after your weight steadies. If the part in your hair keeps getting wider, that's thinning on top.
Does biotin help, like the threads say?
Women on Reddit are split. Biotin feeds the hair, but it doesn't touch DHT. Big doses can mess up blood tests, like a thyroid test. Tell whoever draws your blood that you take it.
Is minoxidil forever?
Pretty much. The label says to keep using it. If you stop, the label says the hair loss comes back. It helps a lot of women, as long as they keep using it.
What about Nutrafol?
It comes up a lot, and so does the price: about $79 to $88 a month, for 4 capsules a day. Its saw palmetto is mixed into a blend, so you can't see how much.
Can I take number one with my shot?
It's two plant extracts, three minerals, vitamin E and a little biotin. Nothing in it is a drug. Still, show the label to your pharmacist first, especially if you take hormones, the pill or a blood thinner.
Still shedding 6 to 9 months after your weight is steady? See your doctor, and ask about iron, thyroid and vitamin D.
Or you close this page. That's allowed.
Nothing happens. The shedding settles, and you keep an eye on the part in your hair.
Next time Reddit says protein, you'll know it's only half the answer.
