What is a direct dye hair color?

Direct dye hair color is a type of hair dye that contains pigments that do not require a developer or chemical reaction to deposit color onto the hair. These dyes typically coat the hair shaft and are known for their vibrant and intense shades. They are generally semi-permanent, lasting through several washes, and are often used for creative or fashion colors. However, direct dyes may fade more quickly than permanent hair colors and can be more challenging to remove.
