Lye relaxers’ active ingredient is sodium hydroxide, Whilst no-lye straighteners depend on sodium hydroxide’s byproducts to accomplish the work. both equally of these aggressive chemical agents can create a extremely alkaline (high-pH) environment monocalcium phosphate feed grade which might be destructive towards the human overall body.

But the reactions at do the job also can melt away the scalp, as well as damaged pores and skin is then vulnerable to other possibly destructive ingredients that these products may possibly have, like parabens and phthalates.
TGA is used like a chemical depilatory and is still used as a result, specifically in salt sorts, like calcium thioglycolate and sodium thioglycolate. TGA would be the precursor to ammonium thioglycolate, that is used for permanents. TGA and its derivatives split the disulfide bonds from the cortex of hair.
