“In addition to biotin, this hair oil contains castor oil and rosemary oil to hydrate and fortify hair,” says Dr. Camp. Not to mention, it also contains caffeine, which encourages growth by stimulating blood flow to your scalp and hair follicles. Reviewers especially love that the formula is lightweight, is highly absorbent, and doesn’t leave hair feeling greasy.

“I have only been using this for about two and a half weeks now, but I am seeing new growth: tiny baby hairs!” writes one shopper. “It soaks in pretty quickly, doesn’t feel greasy, barely smells at all (and what you can smell is pleasant).”
