Does biotin prevent hair loss in women?

Some evidence suggests that biotin can reduce hair loss when it is taken orally, combined with zinc and used in conjunction with a topical cream containing clobetasol propionate, according to MedlinePlus. However, there is not enough evidence available to rate its effectiveness as a hair growth supplement.

Individuals who have biotin deficiencies often experience hair loss, so it is not uncommon for doctors to suggest that patients increase their biotin intake in such instances, according to Healthline. Biotin deficiencies are rare, as the nutrient is present in many common foods, including egg yolks, organ meats, nuts, legumes and whole grains.
