Unlike chemical dyes, plant-based dyes do not penetrate the hair cortex or alter its natural melanin. Instead, they deposit a layer of pigment on the cuticle, which is the outermost layer of the hair. Since they don’t disrupt the hair’s internal structure, this coloring method is much gentler and more respectful of the hair, acting without changing it.
Plant-based dyes fade gradually and naturally with each wash, avoiding the dreaded root effect caused by chemical dyes. The color fades evenly, and its effect can last for weeks or even months.
