Hair dye for dark hair without bleach, a type of hair dye, is formulated to work on hair with a natural dark color, without the use of a separate bleaching agent. An example of its application is using this hair dye to achieve a burgundy shade on dyed or uncolored black hair.
This innovation has become increasingly important in the hair dyeing process. Its benefits include reduced hair damage, as bleaching can excessively dry out hair strands. Moreover, it offers a wider range of color options, allows for more precise color application, and has evolved from early hair dyes with limited color selections.
