64 to 76% of GLP-1 patients lose hair. Your doctor said it would stop.
It has a name. It has a cause. And it is fully reversible once you fix what the medication is taking from you. We will show you why and how.

What is actually happening
It has a name: telogen effluvium.
GLP-1 cuts your appetite hard. Most patients eat 40 to 60% less than before. Your body cannot keep up with nutrient demands through food alone. Ferritin, zinc, and B vitamins all drain faster than you can replace them. When ferritin falls below 30 ng/mL, your follicles read nutritional stress and enter a resting phase. Hair stops growing. Then 60 to 90 days later it falls.
That lag is why you and your doctor both miss the connection. The shedding you notice today was triggered months ago. Telogen effluvium is not permanent hair loss. It's a reversible pause. Once the depletions underneath are fixed at a real therapeutic dose, follicles reactivate and growth resumes. The key word is dose. Standard hair vitamins carry 4 to 5 times less than what the research shows is needed.
The protocol
Three nutrients. All depleted by GLP-1.
Iron (ferritin)
Ferritin below 30 ng/mL puts follicles into dormancy. Most GLP-1 patients hit that threshold within 3 months of starting. Therapeutic doses restore ferritin and reactivate the follicle cycle.
Zinc
Zinc runs the enzymes that keep follicles dividing. Fast weight loss speeds up zinc loss. Without it, GLP-1 shedding looks identical to pattern hair loss under a microscope.
B complex (B6, B12, Folate, Biotin)
GLP-1 slows digestion and drops B12 absorption. Biotin alone does not cover it. The full B complex at real doses is what follicle cell division actually needs.
The mistake most people make
Why biotin alone doesn't work.
Actual biotin deficiency is rare. The shedding you're experiencing is not a biotin problem. It is an iron, zinc, and B complex problem caused by eating much less for months. Fixing it requires doses 4 to 5 times higher than anything in a standard hair vitamin.
That's why so many people try supplements, see nothing, and give up. They tried the wrong thing at the wrong dose. The category is not broken. The products are.
What to expect
The recovery timeline.
Weeks 4 to 6
Shedding slows
Ferritin and zinc begin to normalise. Fewer hairs in the drain. Most patients notice this before anything visible in the mirror.
Weeks 8 to 12
Follicles reactivate
New growth cycles begin. Fine regrowth at the hairline and parting. The first visible sign things are turning.
Months 4 to 6
Density returns
Visible thickening. Starting earlier means the gap you close is smaller. Every week you wait is density you don't get back.
