Which type of hair color is obtained by using oxidative agents?

The type of hair color that is obtained by using oxidative agents is permanent hair color. Permanent hair color products contain a developer, usually containing hydrogen peroxide, that provides an oxidative reaction. This reaction allows the color to penetrate deeply into the hair shaft, resulting in a long-lasting change in the hair color.

When permanent color is applied, it not only deposits color but also lifts the natural pigment of the hair, allowing for a more significant transformation and a wider range of color options. This type of coloring is designed to last until the hair grows out or the color is cut off, making it ideal for individuals seeking a durable and consistent hair color.

In contrast, semi-permanent and demi-permanent colors do not typically contain strong oxidative agents. Semi-permanent color generally adheres to the surface of the hair and gradually washes out over time without any lifting of the natural pigment. Demi-permanent color, while it does use low levels of peroxide to slightly lift the hair, does not have the same lasting power as permanent color. Temporary color is often the least durable, designed to wash out after a few shampoos and is used mainly for short-term changes.
