All texturizers and releaxers are made from sodium hydroxide, right? So would it be problematic to switch from brand to brand? I wonder, because I did my first texturizer about two weeks ago and didn't get the results I totally wanted; I am not sure if the relaxer was too weak or if I just didn't let it process long enough. Therefore, I am wondering if and when I try it again, if I should try the same brand for a longer processing time or if I should try a different, stronger formulation altogether?
