Which type of hair color is designed to lighten and deposit color at the same time?

The type of hair color that is designed to lighten and deposit color simultaneously is permanent color. This formulation contains a mixture of ammonia and a developer, usually hydrogen peroxide, which allows the color to penetrate the hair shaft. The lightening process happens because the developer opens the cuticle layer, allowing the color molecules to enter and alter the natural pigment of the hair. This enables the hair to become lighter while also infusing it with the desired color.

Permanent hair color has the unique ability to lighten existing hair color and introduce new shades, making it highly effective for those looking to significantly change their hair color or cover gray hair. Unlike the other options, which focus either solely on depositing color without a lightening effect or offer only temporary changes, permanent color ensures a more lasting transformation that requires a reapplication for maintenance as the hair grows and the color fades.
