What type of hair color is pre-oxidized and lasts through several shampoos?

Semi-permanent hair coloring is designed to penetrate the hair shaft and provide color that can last through several shampoos. The pigments in semi-permanent color are pre-oxidized, meaning they have been processed in a way that allows them to bond with the hair without requiring a developer or the use of ammonia. This results in a color that is less intense than permanent hair color but offers greater longevity than temporary hair color.

Semi-permanent coloring typically lasts anywhere from a few washes to several weeks, depending on factors like hair condition, the porosity of the hair, and the frequency of washing. This makes it a popular choice for individuals seeking a color change that is less committal than permanent dye options. It is ideal for enhancing natural color, blending grays, or experimenting with fashion shades without the long-term commitment associated with permanent hair dyes.
