What is the term for the partial or total removal of natural pigment or artificial color from hair?

The correct term for the partial or total removal of natural pigment or artificial color from hair is hair bleaching. Bleaching works by using chemical agents to lift the color from the hair, making it lighter. This process can be used to remove both natural hair color and artificial dyes, making it a common technique for achieving lighter shades.

Hair lightening is often used to describe a broader process that may include subtle changes to hair tones but doesn't specifically refer to the chemical removal aspect found in bleaching. Color stripping refers to products designed specifically to remove artificial color from hair but doesn't encompass the full scope of hair bleaching. Color correction typically involves adjusting or fixing unwanted tones or colors rather than the removal of pigment. Thus, bleaching is the most accurate term in this context.
