Copper, a mineral found in avocado, is one of the best nutrients that fortify both hair and skin.

"Copper builds up the collagen and elastin of the skin that holds the hair follicle," said Dr. Ellen Marmur, a board-certified dermatologist and associate clinical professor in the department of dermatology and the department of genetics and genomic research at the Icahn School of Medicine at Mount Sinai in New York City.
Copper also helps to balance the hormones so hair grows strong and aids other reactions in the scalp that strengthen lipids in the hair. Other copper-rich foods include shellfish, veal, beef, whole grains, dark leafy green vegetables, beans and legumes, nuts and chocolate. #FoxNews
