How important is biotin for hair growth?

Biotin, also known as Vitamin H is part of the B-complex vitamin family, and can be found naturally in a variety of foods we eat.

Biotin is a water soluble that produces keratin(a form of protein), increases hair elasticity, and protects hair from dryness. It also helps thicken hair to give it a more fuller appearance.

Biotin aids in the metabolization of fatty acids, amino acids, and plays a role in the stabilization of blood sugar levels. The amino acids produced when biotin is ingested plays a major role in hair growth. Amino acids are the building blocks of protein, and since hair itself consists of protein, biotin can be labeled as "catalyst" for strong, healthy hair growth.

Biotin deficiencies are associated with hair loss, unexplained hair breakage, and cracked, brittle nails. Though biotin deficiency isn't commonly encountered, it can develop in individuals who consume an excessive amount of alcohol, and in individual who maintain a poor diet.
 
So to answer your question: How does biotin aid hair growth?
Biotin not only promotes healthy hair growth, it also prevents hair dryness. When used for a period of 6 months or more, biotin aids in the production of healthier hair follicles which translates to stronger, longer, fuller and healthier hair.

Biotin also aids in the reduction of hair breakage by increasing hair elasticity, which means, hair grows longer and stays stronger over the course of a short time. If a person is suffering from hair loss, taking extra biotin may aid with healthy, fuller hair growth, due to the internal activities biotin enhances and activates.
