GLP-1 & your hair
Best Supplement for GLP-1 Hair Loss? 5 Bottles, Ranked by the Label
On the shot or about to start? We read the back of 5 popular hair supplements. Only one gets all 5 checks right.
- Most GLP-1 hair loss is shedding all over, from fast weight loss. It usually stops by itself.
- Some women also thin on top while the back stays thick. A hormone called DHT causes that part.
- Most hair vitamins only feed the hair. Only one of the 5 below gets all 5 checks right.
For thinning on top, pick one that works on DHT, the hormone behind it.
Look for two plants on the label: pumpkin seed oil and saw palmetto. Both amounts should be printed, and the biotin should be low.
Only number one below gets all 5 right. You can take it on the shot or before you start.
The shot is doing its job. The weight is coming off, and more hair than usual is coming out with it.
Or you haven't started yet, and you've read enough to worry about your hair.
Either way, you want one good bottle to take with the shot.
They all look the same from the front. The back label is where they differ.
Why the top thinsWhat's going on
Losing weight fast can set off shedding all over your head. That usually stops by itself. Thinning on top is a different problem.
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, which women make a little of 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.
- 1The shot takes fat fast
That's how the weight comes off so quickly.
- 2Estrogen drops with the fat
Part of your estrogen is made in fat, so less fat means less estrogen.
- 3DHT wins on top
The roots on top shrink, and the back stays thick.
How it startsHow you got here
For most women, the shedding shows up around month 3. The brush fills up, and the ponytail feels thinner in your hand.
Then everyone has advice: protein, biotin, collagen, a hair gummy, or wait it out.
I TRIED to prevent it … by eating more than enough protein, taking a multi vit, a hair skin and nails vit and collagen...no dice.
From a Mounjaro thread
Protein matters. It protects your muscle while the weight comes off, so keep it up.
But protein and most hair vitamins only feed the hair. They do nothing about DHT.
If you haven't started yet, you have about 3 months before shedding usually starts.
The checksThe 5 things that matter
The 5 things to look for
Here's what to look for on the back of the bottle.
- Made for women. It says women on the front.
- The DHT job. It has pumpkin seed oil and saw palmetto, with the amounts.
- Every amount printed. A number next to each ingredient. No “blend.”
- Easy on blood tests. Low biotin and no iodine, so your blood tests stay accurate.
- Two a day or less. Easy to keep taking past month 3.
We checked every bottle below on these same five things.
The ranking5 hair supplements, worst to best

- Every amount One total for its hair blend
- Blood tests 6,000 mcg biotin, plus iodine

Verdict. The best-known name, and the bottle Nutrafol shows women on its GLP-1 page. You can't see how much saw palmetto is in it. A month costs more than 12 weeks of number one.

Number oneWhat's inside number one, and how it works
Two softgels a day. Here is every amount, straight from the label.
| Ingredient | Per day | What it does |
|---|---|---|
| Pumpkin seed oil, cold-pressed | 1,000 mg | Helps your body make less DHT at the root |
| Saw palmetto extract | 320 mg | Also helps your body make less DHT |
| Zinc | 10 mg | Helps hair grow normally |
| Selenium | 55 mcg | Helps keep hair and nails healthy |
| Copper | 1 mg | Helps hair keep its color |
| Vitamin E | 50 mg | Helps protect cells from everyday wear |
| Biotin | 100 mcg | Low on purpose, so your blood tests stay accurate |
| Iodine | None | Left out on purpose |
Estrogen helps guard the roots on top. On the shot, part of it goes with the fat.
At the root, your body has a tiny helper called an enzyme. It turns some of your testosterone into DHT.
DHT is the hormone that makes each new hair on top grow in finer.
Both plants slow that enzyme, right at the root. So less DHT is made there.
Each plant does it in its own way. You don't need a prescription.
Pumpkin seed oil is pressed cold from the seeds, like a good olive oil. Saw palmetto is the berry of a small palm that grows wild in Florida.
There's one trial, and it was in men. They took 400 mg of pumpkin seed oil a day for 24 weeks.
Their hair counts went up about 40%. There's no trial in women yet.
Number one has 1,000 mg a day.
It's the only one here with 1,000 mg cold-pressed pumpkin seed oil and 320 mg saw palmetto.
The biotin is kept low, at 100 mcg, and there's no iodine. It's made for women losing hair on top, on the shot or about to start.
There's no blend. Every amount is printed.

QuestionsWhat women ask about hair supplements on a GLP-1
Which supplement is best for GLP-1 hair loss?
For thinning on top, pick one that works on DHT, with both plant amounts printed and low biotin. Only number one here gets all five right.
Should I start before my shot, or with it?
Either works. Shedding usually starts around month 3. Hair needs about 12 weeks to show a change. Start both at the same time, and you're 12 weeks in by month 3.
Do biotin or collagen help?
They feed the hair. Neither does anything about DHT. Big biotin doses can throw off blood tests, so tell whoever draws your blood.
Can I take number one with my shot?
Nothing in number one is a hormone or a drug. Show the label to your pharmacist first. That matters most if you take hormone therapy, birth control or a blood thinner.
How long before I see a difference?
Give it 12 weeks. For the first 4 weeks, you won't see much. Check your part at week 8, and decide at week 12.
Or you close this page. That's allowed.
Nothing happens. The shot keeps working, and you keep an eye on the part in your hair.
You know the five things now. Next time, check the back before you buy.
