I color my hair every month and I've tried everything the European market has to offer without ever being truly satisfied.
This was a game changer for me. First of all it doesn't smell like chemicals and is actually pleasant!
It applies very well and covers white hairs incredibly. The color is a brownish black that is incredibly natural, in terms of hue the best I've ever tried.
The only downside is that if you have long hair you will need 2 if not 3 tubes as 1 tube was enough to completely cover my hair upto my ears.
in conclusion LOVE it!!!
