Does biotin make your hair grow longer and faster?

Biotin can stimulate hair growth in individuals who have a biotin deficiency. However, biotin deficiency is rare, and it is important to consult a physician before taking biotin supplements to determine if they will actually be beneficial.

When an individual experiences biotin deficiency, she may experience brittle nails and hair loss. Biotin supplements repair this problem by improving the infrastructure of keratin, which is a basic protein that makes up hair, skin, and nails.

Some individuals take biotin to stimulate new and rapid hair growth. Biotin is a B-complex vitamin that works to stimulate growth by helping the body to process energy.
