I have never heard of it before. This is all I found --
Organic Color Systems Packages

It looks like their lowest level of peroxide they use is 10%. That isn't really bad but it's going to be more harsh than RC Color.

Most salons will not apply color for you if they do not carry the brand. I think it's a liability thing.

If your hair is healthy, you should be ok with this, but make sure they use a light enough color so you don't get darker hair.

If not, try the RC route. It will be much cheaper!
