Biotin for Hair: What It Is & Why It’s Used in Haircare

What is biotin?

Biotin, also known as vitamin B7, is a vitamin frequently featured in haircare and beauty products. In topical hair products it is generally used as part of a broader conditioning or scalp-care formula.

Why is biotin used in haircare?

Biotin is commonly included in shampoos, conditioners and leave-on hair products marketed toward fuller-looking, well-conditioned hair. The performance of a topical product depends on the complete formula rather than one ingredient alone.

What should you expect from topical biotin?

Cosmetic haircare can help hair feel conditioned, manageable and healthy-looking, but topical products should not be presented as treating an underlying medical cause of hair loss.

Building a haircare routine

Choose products based on your scalp, hair type and styling needs. Gentle cleansing, appropriate conditioning and avoiding unnecessary mechanical or heat damage can all contribute to healthier-looking hair.
