COSMTEK Black Dye Shampoo is a 3-in-1 dye shampoo that colors hair while it cleanses, aimed at covering gray and white hair on the head and beard. It is formulated without ammonia and is marketed as lasting up to 30 days. It suits people who want a quick at-home touch-up rather than a salon appointment or a full dye kit. Against box dyes it is simpler to apply but gives less control over shade and coverage, and lasting power depends on how often you wash.
