What are chemical compounds that lighten the hair by dispersing, dissolving, and decolorizing artificial pigment?

Permanent dyes
Shampoos
Conditioners
Lighteners

The correct answer is: Lighteners

Lighteners are chemical compounds that can lighten hair by removing artificial pigment. Permanent dyes, shampoos, and conditioners do not have this ability as they are not made to effectively remove existing color. Permanent dyes, as the name suggests, are meant to dye the hair and change its color. Shampoos and conditioners are used for cleaning and conditioning the hair and do not contain strong enough chemicals to lighten hair.
