I stopped going to my stylist who used it on me. She kept telling me that I couldn't get it unless I had a license which in her way meant, "I won't buy it for you".

I got a 4 lb tub for $46 - that's including s&H and my touch ups at the salon were $70. When I run out of my other 'poo and 'con products I'll convert over to DE completely. The seller I purchased from was

It was quick, professional and they were very good at responding to my questions.
