I have used both ORS no-lye and mizani no-lye and mizani lye relaxers. I love both ORS relaxers and mizani lye relaxers. I found that the no-lye relaxers no matter which brand left my fine strands looking and feeling lifeless and dull.
I like Mizani lye relaxer much better which I add some evoo or almond oil to, and I believe the reason for that is that I follow Sistaslick's well guided steps to the relaxer, like low manipulation leading up to the relaxer day, protecting my hair strands with some type of oil or moisturizer (I use profectiv break free of Cantu break cure for this) basing properly with vaseline or some heavy petroleum type grease, the 5 minute protein pre-treatment, leaving the neutralizing shampoo's final wash on for 5 minutes, and increased protein moisturizing and treatments before, during and after the relaxer process.
Now I don't have anymore scalp burns, no more hair breakage, and my hair is softer and so much more manageable. I thank God that I found these important steps to the relaxer. I was ruining my hair by my lack of knowledge in dealing with my hair.
