Biotin is one of the B vitamins. Otherwise known as B7, a deficiency can cause hair loss, nerve damage and skin health. You’ll find high amounts in food like eggs, sweet potatoes and our old friend, spinach.
Biotin affects how some medications work so talk to your doctor before starting supplements. Eating food with biotin levels should not be an issue.
So far, spinach is a clear leader in healthy hair foods. What else is good for you?
