How Long Does It Take For Permanent Hair Dye To Fade Completely?
Permanent hair dye takes a long time to fade completely, as it is designed to last for weeks or even months. The fading process can vary depending on the brand of dye used, the condition of the hair, and how often it is washed. Typically, permanent hair dye will gradually fade over several weeks to months, but it may take up to six months or more for it to completely disappear.
