What is it?
Biotin is a B-vitamin that is important for healthy hair, skin, and nails. It is also known as vitamin H or vitamin B7. Biotin plays a role in the production of keratin, a protein that is a major component of hair, skin, and nails. It is also involved in the metabolism of fats and amino acids, which are the building blocks of protein.
Some studies have suggested that biotin supplements may be effective in improving hair growth and thickness. For example, a study published in the Journal of Clinical and Aesthetic Dermatology found that biotin supplements were effective in improving hair growth and thickness in women with thinning hair. Another study published in the Journal of Cosmetic Dermatology found that biotin supplements improved hair growth and reduced hair shedding in women with hair loss.
