I have used nothing but Vitale since I was about 11 or 12. My beautician at the time used it, and so that's what I kept up with. There was some other relaxer I was using before that, but it gave me the kind of perm burn that left my eyes rolling. (Part of that was me scratching. The other part makes me believe that relaxer was suspiciously strong.) I was pissed that the beautician used the relaxer on my head knowing I had an open scratch like that, and I chose never to go with her again. But she is the person who introduced me to Vitale, so I have to give her credit where credit is due. Twenty-five years later, and this is still the only relaxer I'll use. I buy the moisturizers, actual olive oil, shampoos, conditioners, etc. Vitale is pretty much my go-to. This relaxer also worked well. I kinda prefer the ones with the liquid activator over ready-made versions, but this was cool.
