What is a developer in hair coloring?

A type of conditioner
An oxidizing agent that enables lightening
A non-oxidative color
A tool for decolorizing only

The correct answer is: An oxidizing agent that enables lightening

A A type of conditioner is incorrect because a developer is not a type of conditioner. A developer is a chemical product that is used in conjunction with hair dye to facilitate the color process by breaking down the molecules in the dye and helping it penetrate the hair cuticle. C: A non-oxidative color is incorrect because a developer is specifically an oxidizing agent. Non-oxidative colors do not require a developer and instead rely on direct dyes to deposit color onto the hair. D: A tool for decolorizing only is incorrect because a developer can also be used for coloring the hair. While it is commonly associated with lightening or decolorizing, developers are also used in semi-permanent and demi-permanent hair dyes to help the color penetrate the hair shaft.
