In the past, everytime I've relaxed my new growth, my hair would come out super lifeless and flat. I would have to tease my hair to get more body, which obviously harms the hair cuticle.
Doing a rinse with Porosity Control conditioner after neutralizing followed by the Porosity Control Shampoo works for me. You can skip the shampoo part, but I find that the two work well together. But even with the conditioner rinse alone I can tell.
