Subjecting a child that young, who hasn't even hit puberty yet, to a chemical relaxer, where the relaxer chemicals can burn the fucking skin, should be viewed as child abuse. Letting that child scream and cry because it burns, because they wouldn't sit still so the base cream could be fully applied is just deplorable and cruel. My god, if you honestly can't maintain your own kid's hair, keep it short or keep it in braids. Also - not washing your kid's hair for three to four weeks at a stretch is really disgusting.
