Well, they say Salerm products are not really dominican, but I am currently using there relaxer. Mind you I am very textulaxed not bone straight by a long shot. Just relaxed 4a coils, but still very textured. I use the lye and have had no problems with it. The one thing I noticed when attempting to do my mom's hair is that it takes longer to get it really straight. It doesn't seem as strong as other relaxers I used back in the day cause it deosn't straighten as much.
Overall It's cool, but you might have better feedback from someone that goes entirely straight.
Hope this helps
