I used to use Precise No Lye for years throughout the 90s. IMO, it was a very good relaxer. You have to mix it, so I would always wind up wasting some, but its not expensive. Hmmm, now you've got me wondering why I stopped using it....I was natural for about 6 years, and when I went back to relaxing, I had forgot all about good old Precise. I never got scalp burns with this relaxer, as I often get with Mizani Lye mild. ***thinks maybe I should switch back***
