Relaxers or Hair killers?

So today, I am going to touch on a touchy little subject that is dear to many women's hearts-a relaxer.I wonder how many women who actually relax their hair actually know what is inside their little home kit or professional tub of relaxer? Across the board, there is one primary ingredient in all relaxers, and that is lye. Lye is sodium hydroxide(chemical formula NaOH) and this product is substituted in no-lye relaxers by Potassium or Calcium Hydroxide(KOH and CaOH respectively). Lye is known to be caustic and is used in many cleaning products.
