Which type of hair color lightens and deposits color at the same time?

Permanent hair color is capable of both lightening and depositing color simultaneously due to its unique chemical formulation. It contains a higher level of alkaline agents, which opens the hair cuticle and enables the color to penetrate deeply into the hair shaft. The oxidation process that occurs with permanent dyes allows them to lift the natural pigment in the hair while simultaneously adding new color. This dual action makes permanent hair color versatile for achieving a wide range of shades, whether one is looking to go lighter, darker, or change the tone entirely.

The other types of hair color each serve different purposes. Demi-permanent color primarily deposits color without significantly altering the hair's natural level, making it excellent for enhancing tone or covering grays but not for lightening. Temporary hair color coats the exterior of the hair shaft and does not penetrate deeply, providing a non-permanent change without lifting the natural color. Pastel colors generally utilize techniques that lightly tone already-processed hair rather than providing significant lift. Thus, permanent hair color is the most effective option for achieving both the lightening and depositing of color in a single application.
