Hello, I am a salon owner in the Upper Peninsula of Michigan and I have been using this product for about 2 years. I love the idea of it being non-toxic and have found all of my allergy symptoms I have exprienced from other colors are gone! I had absolutely no problems converting formulations from Framesi color. It was just exactly asthe conversion chart stated. rest assured you can't make a mistake!!! And the feel of the hair has been a bonus too. I had previously used Redken Color Gels and there is no comparison in the texture and feel. Eco-Color is a very superior product!
