Brewer’s yeast is a rich source of biotin, which is essential for hair growth. Biotin is a coenzyme that helps the body break down and build up protein. This affects hair growth because hair is made of a protein called keratin.
Brewer’s yeast contains many nutrients important for healthful hair. It contains the B vitamins biotin, riboflavin, thiamine, niacin, pantothenic acid, pyridoxine and folic acid. It’s also a big source of selenium. All of these nutrients contribute to the health of your hair.
Niacin boosts scalp circulation, and helps in the digestion of fats, proteins and carbohydrates,which are the building blocks of healthy hair and skin.
Brewer’s yeast contains selenium. Selenium works hand in hand with vitamin E to destroy free radicals that damage cell membranes. Lack of vitamin E or improper ability of the body to use vitamin E can lead to dry or dull hair and hair loss. Selenium also improves the elasticity in skin and hair.
