Abstract
By intermixing a gelling agent, water, a mercaptan-based reducing agent, and a certified dye designated as an F,D&C dye and/or a D&C dye, a highly effective, easily employed permanent dye/gel composition is obtained which imparts a desired color into both natural and synthetic fibers. In the preferred embodiment, the mercaptan-based reducing agent is added to the composition immediately prior to applying the permanent dye/gel composition to the fibers. By merely rubbing, or embrocating the permanent dye/gel composition into the natural or synthetic fibers, the desired color is permanently embedded into the fibers in a long-lasting durable manner. In view of the constituents employed in this permanent dye/gel composition, use as a permanent hair dye is highly effective.
