Hair coloring

Hair coloring or hair dyeing is changing the color of hair. Common reasons are to cover gray hair, to change to a color that a person likes better, and to return the hair to its normal color after it has been badly changed by hairdressing or sun bleaching. The 1661 book Eighteen Books of the Secrets of Art & Nature explained ways of coloring hair black, gold, green, red, yellow, and white .^[1]
