Todays generation has veri big problem off white hairs. So most of people using colors to make black from white hairs. I am not using this but my mom use it.
Before streax she was using another hair color but then she had to face eyes problem. Then I suggest to mom use this color. The best thing about this it has not any side effect on eyes or skin.
This is long lasting color. Easily it takes one and half month. It is too natural also. We can not judge hairs are natural or colored. Genuine is price according to its quality and quantity. It iss easy to use also.
Go for this color it is best. You will definately like it.
