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 &amp; Nature" explained ways of coloring hair black, gold, green, red, yellow, and white .
Types of hair coloring.
The four common types of hair coloring are "permanent", "demi-permanent" (sometimes called "deposit only"), "semi-permanent", and "temporary".
