Biotin (vitamin B7) supports healthy hair. About 300 micrograms a day, taken with food, is a sensible amount. More isn’t better: too much biotin can upset your stomach, cause breakouts and throw off medical lab tests.
How much biotin should you take for hair?
About 300 micrograms a day, with food. Megadose biotin products often contain far more than you need, and the extra doesn’t grow more hair.
Biotin side effects
- Upset stomach: take it with food.
- Breakouts: high doses can cause acne in some people.
- Lab test interference: biotin can make some blood tests read incorrectly. If you’re having blood work done, tell your doctor you take biotin.
Is biotin enough on its own?
Usually not. Hair loss after 45 often has several causes at once: DHT, nutrition, scalp health, sleep and stress. Biotin addresses one small piece. If you’re thinning, a complete multivitamin plus a plan for the other causes will do more than biotin alone.

Frequently asked questions
Does biotin regrow hair?
Biotin supports healthy hair, but it won’t fix thinning caused by DHT or scalp problems. For that, look at a prescription hair serum.
Can I take biotin with a hair serum?
Yes. Supplements and topical serums work on different parts of the problem.
Should I stop biotin before blood work?
Ask your doctor, and always tell them you take it.
