From my experience, this product is really good. It gives natural black color to our hair and the hair will be shiny. In addition to this, the black color lasts for long when we compared this product with other hair dyes. So overall it is good. I will recommend this product to all people who suffer by white hair but first you guys should do a preliminary test to know whether it has any allergic problem in your body.
This product should not be used for dyeing eyelashes or eyebrows as its use may cause blindness.
