I use silk elements no lye relaxer,but have been using Mizani butter blends PH moisture bath (something like that) for over a year because it is a chelater and neutralizing shampoo. I love it ! I hated the butter blends relaxed though...
I use (and love) Linange Shea Butter Lye, but I use Elucence Acidifying shampoo.
Linange has a neutralizing conditioner (not shampoo) and while I hear it works very well, I haven't wrapped my head around a condioner to neutralize after relaxing.
Elucence Acidifying works very well and my hair is not stripped feeling at all. Another bonus is that the tiniest amount gives a very heavy lather...the bottle will last me years.
I use ORS relaxer and Isoplus neutralizing shampoo
