I have been using eSalon for many years and have never had a problem. It is the color you yourself order and if need be can contact a professional and speak with a colorist.
The only ones that seem to have a problem with the product are those that like to soak you for a great do yourself at home. Beauticians are not making money off of you this way. I have colored my hair and have at times gone in to my beautician for highlights. And she has also done my hair for years and says my hair is healthy and I know it is as well as soft and has great color that shines.
It's easy and works fantastic. Unless maybe if you don't read the directions.
