Biotin, also known as vitamin B7 or vitamin H, is a water-soluble B vitamin that plays an essential role in the metabolism of fats, carbohydrates and proteins. It acts as a coenzyme in various metabolic reactions that are necessary for energy production and the synthesis of certain building blocks.
In the context of hair, biotin plays an important role in maintaining its health. Biotin is believed to contribute to the production of keratin, a protein that is a major component of hair, nails and skin. A lack of biotin can lead to hair loss, brittle nails and skin problems, although a true biotin deficiency is relatively rare.
Biotin supplementation is often recommended for people who want to improve their hair strength and counteract hair loss. Many hair care products and supplements contain biotin with the promise of promoting hair growth and improving hair quality. While scientific studies show mixed results on the effectiveness of biotin supplements for people without an existing deficiency, some people report positive effects on their hair growth and hair health with regular use.
A balanced diet rich in biotin-rich foods such as eggs, nuts, seeds, fish and certain vegetables can help to meet daily biotin requirements and support overall hair health.
