NATURCOLOR is an herbal-based high-quality permanent hair color gel designed to change or enhance one?s existing hair color. It was formulated for those who are ecologically minded and may be coloring their hair for the first time. Naturcolor is not for women only. Men can discreetly color their hair with it at home, and it?s great for beards and mustaches. Naturcolor pigments color with a subtle transparent effect. Your gray hair will take the color differently than the darker portions of hair allowing for subtle color on color tones that look natural and never appear ?dyed?. It can be used to add subtle, but radiant highlights, or to dramatically change your existing hair color. It will not fade as other hair color products do. NATURCOLOR was designed for chemically sensitive people and every effort has been made to substitute safe, natural ingredients for the harsh often dangerous chemicals that pervade the hair-care industry. Naturcolor comes in 31 colors classified as: Natural (N), Ash (C), Mahogany (M), Copper (R) and Golden (D). * and a complete application takes less than an hour *Naturcolor recommends a skin sensitivity test.
