You can use this hair color without being worry for damaging your hair. I have been using this hair color for four months now and my hair is changing to be alive again. My daughter is vegan and she recommended me this vegan friendly product. I bought color 6N and 5N and I loved both. At first and second wash it seems darker than actual color. After a couple of washes you achieve the natural color you were looking for. This product has very natural scent it doesn't bother you at all during coloring and washing.
