What Vitamin Helps Hair Grow?
Safeguard your hair's health and ability to grow by taking daily vitamin supplements, and/or by eating an extremely well-balanced diet that provides your hair with the nourishment it needs. Hair can't grow if it isn't nourished properly.
Effects of Vitamin B
Biotin is one of the B vitamins. It's considered "food" for the hair. It produces keratin, which is an integral component of hair, skin and nails.
Other Considerations
The other B Vitamins, including B5 and B12, help hair remain healthy and growing. Vitamin B5 actually helps your hair maintain its pigmentation (color) and may thwart the onset of graying.
