Niacin, a form of vitamin B3, improves blood circulation and brings oxygen and other nutrients to the hair follicle allowing hair to grow fuller and thicker. Additionally, like many vitamins, Niacin plays an important role in providing energy for cell growth and metabolism pathways in the body. Studies have shown that it can help with female pattern alopecia.
