Drink Lots of Water
Dehydration directly impacts hair growth. No matter what you do like taking vitamins or hair supplements if you are not getting enough water your hair will not grow. Roots of hair are the only means by which water is supplied from body to hair. Roots soak up the water and provide hydration to the hair, which automatically and internally boosts up hair growth. If your roots are water deficient the hair becomes brittle and dry causing the hair to stop growing at its genetic rate. 8 cups of water a day are recommended.
