The shot didn't take your hair. The drop in food did.

Your GLP-1 does exactly what it promised: you eat about half of what you used to, and the weight comes off. But your body runs on survival wiring that has never heard of Mounjaro®. All it sees is the data: food intake just dropped by half, and it's staying down. In every century before this one, that meant famine.

So it triages. Heart, brain, lungs, liver: fully funded. Hair — the one part of you that is biologically optional — gets the order: stop spending here. Follicles get switched out of growth on a two-to-three-month delay, which is why it shows up right when the weight loss is finally working, and why it feels sudden. It isn't.*

You were already fighting DHT. The shot opened a second front.

Most men over 45 have some DHT pressure on the follicle already — that is the slow recession you have been watching for years. What is different now is that fast weight loss shifts hormone balance and leaves the follicle more exposed to it, at the same moment the famine order is cutting its supply. Two hits, same follicle. That is why “a little thin on top” turned into a crown you noticed in a photo.*

Hair Shield holds that line with the two botanicals most studied for it, at the doses used in the research: saw palmetto extract 320 mg (45% fatty acids) and pumpkin seed extract 4:1. In a 24-week randomized controlled trial, pumpkin seed supplementation increased hair count 40% versus 10% for placebo. Hormone-free. Not a prescription. No rebound shed when you stop.*

Half the food means half the iron and zinc reaching the follicle — even if your labs are “fine.”

On a half-sized diet the iron, zinc, vitamin D, B12 and folate you do eat get routed to the organs first. Follicles are last in line, and a slowed gut absorbs less on top of that. Your bloodwork protects the bloodstream; it does not see what the follicle is getting.*

So the refill comes first: iron 18 mg (100% DV, gentle bisglycinate), zinc 15 mg, vitamin D3, methylated B12, folate and biotin 5,000 mcg — the five reserves a GLP-1 eating pattern drains first, in forms a slowed gut can actually use.*

Stress shed is real for men too. It has its own switch.

Dropping weight fast is a physical stressor even when it feels like winning. The cortisol pressure it keeps on the follicle locks hair in the resting phase. Ashwagandha root extract standardized to 5% withanolides — the potency used in research where ashwagandha lowered cortisol by roughly 27% — releases that lock so refilled follicles can go back to work.*

The biotin gummies and the barbershop shampoo answer a different question.

Biotin helps if you are deficient. Most men aren't. Thickening shampoo coats the shaft for a day. Minoxidil forces blood to the scalp, sheds you harder for the first weeks and stops working the day you stop. None of them answers a famine order or a DHT hit. They were all the right answer to a different question.*

Two capsules with dinner. No routine to remember, nothing to rub in.

Here is the whole protocol: two capsules with dinner and a glass of water. That's it. $39.99 a month with Subscribe & Save — $1.33/day, less than the shelf of things that never worked, and a rounding error next to what the shot itself costs each month. Cancel anytime.*

84% report less shedding within 6 weeks. Here is what the 90 days look like.

Hair works in 90-day seasons. Anyone promising overnight regrowth is lying to you. This is what most customers report:*
