Black repigmenting shampoo, made with 92% natural ingredients, is specially formulated to provide a black tone to the hair in a comfortable way, as if it were a normal shampoo. Because it is not a dye, but a colouring shampoo, it does not damage the hair structure or damage the scalp, as it does not contain ammonia, hydrogen peroxide, resorcinol, silicones or parabens.
