It has been a long time since I use the Isoplus Relaxer System, No-Lye Conditioning, Regular. The reason I used it at the time was because it was new. I always tried different relaxers. And every time when they had a new one, I would try it. I did not see anything differently it had done to my hair. It seems like at the time, most relaxers were made the same. But now they are made different by adding milk, or olive oil or other different type of oils. They all seems to be the same at the time. I haven't used it in a while to notice if it improved, but I have no intention on trying it again.
