Permanent haircolor is capable of which of the following?

Permanent haircolor is capable of lightening and depositing color because it contains ammonia or a similar alkaline agent that opens the hair cuticle, allowing the color molecules to penetrate the hair shaft. This process enables it to lift the natural pigment of the hair (lightening) and simultaneously deposit the new color.

When using permanent haircolor, the developer (usually hydrogen peroxide) works in conjunction with the color to oxidize the natural pigments in the hair, effectively lightening them. At the same time, it adds new pigments that provide the desired shade, making this type of haircolor versatile for various hair coloring techniques.

This dual action of lightening and depositing makes permanent haircolor suitable for covering gray hair, creating dramatic changes, and achieving a wide range of colors. The ability to do both is a significant advantage when clients want to alter their hair color significantly while ensuring lasting results.
