I had a sample of some aubrey shamp (cant remember the name, but i told the lady send me the shamp for dry hair) and It actually dried my hair out!!!
Non SLS shamps are Creme of nature, white bottle green writing (my personal fav)
Breakthru shamp.. leaves my hair feeling likee i already conditioned it..
others like the old L'anza Proetin Plus shamp (i haven't tried it yet).
