My hair has started becoming white, that’s why I started using it. Unlike to other products available in the market this product is quite handy and easy to use. Its black colour and pleasant smell compels me to use it only. One offensive thing is when you apply it on your hair hands or fingers get black coloured. So while using it extra care should be taken. Also after applying this on hair one must not lie on a bedsheet, pillow or any such materials because those things too get coloured that is very hard to get rid of. It has great effect on lice. Lice gets completely killed by this product. I have personally experienced that. One there was times when I used to have a lot of lices in my head. But the time since I started using it all the lices just vanished from my hair. This product is very user friendly. One time application prevents re greying for almost 6 months. I really loved this product.
