Along with Corrina's suggestion for checking dew points, I can try all this - good idea.
Right now I don't have a system. I have to say my hair does not get slip from many things except KCKT and a few others so I rarely cowash. Plus I always feel like I have build-up and I often use Skinny Suds by Botticelli Botanicals or Castille Oil (baby) - every so often I do a prell wash just to clarify.
But I can try this. I just don't know what condish or LI I'd use since NOTHING IS WORKING and I'm afraid my hair is reacting to everything -
At least I'm positive I can't use protein but I'm still not sure about coconut, panthenol, glycerin and aloe, so I basically am afraid to even try!
