To understand the link between zinc and hair growth, you should first know the connection between deficiency in zinc and hair loss. Some experts believe that zinc deficiency actually can lead to deterioration of the protein structure that makes up the hair follicle.This weakening of follicles can, in turn, cause hair shedding and hair loss.
Zinc is also believed to play a crucial role in DNA and RNA production. This is required for the normal division of hair follicle cells, leading to healthier hair growth.
Zinc also may help keep hormone levels balanced, which could be one of the reasons why it is so effective in preventing hair loss. There are even a few outlying studies in which people’s grayed, aged hair returned to its original color when nourished with zinc-rich diets or hair growth supplements. As a bonus, zinc for hair growth may help eliminate dandruff on the scalp as well.
