Your hair and nails are simply modified skin cells. Because they are modified skin cells, they require many nutrients to maintain their rapid growth. If these nutrients are not present, their growth can slow and their appearance as well as strength can be negatively affected.
Hair and nails are also comprised largely of protein, and due to the rapid growth, benefit from the following vitamins: vitamin E, vitamin C, vitamin B6, Biotin, vitamin b12, and vitamin A. When using a hair and nail supplement you should start seeing results after a few weeks. This will give your hair and nails a chance to grow out with all the beneficial nutrients.
