What is the process of partial or total removal of natural or artificial pigment from hair called?

The process of partial or total removal of natural or artificial pigment from hair is known as hair lightening. This method involves using specific products and techniques to reduce the darkness of the hair color by eliminating or diluting pigment. Hair lightening allows for a range of shades, often creating a lighter appearance without necessarily reaching a complete white or blonde color.

In the context of hair services, lightening is distinct from other processes like coloring, which usually involves adding pigment to the hair, and toning, which is typically a secondary treatment meant to adjust the tone of already treated hair. Bleaching, while commonly used interchangeably with lightening, specifically refers to more aggressive techniques often aimed at reaching very light shades or removing color more quickly.

Thus, understanding hair lightening as a method of pigment removal is crucial for correctly approaching hair color services and achieving the desired outcomes for clients.
