How Long Does Black Dye Last In Hair?
The duration of black hair dye lasts depends on several factors such as the quality of the dye, hair texture, and level of care. On average, permanent black hair dye lasts for six to eight weeks. However, with proper maintenance and protection from sun and heat, the hair color can last up to six months. Semi-permanent black hair dyes tend to fade within 4-6 weeks, and temporary black hair dye fades after a single wash.
