how does a perm work chemically

Best answer


In a standard 鈥昪old鈥?perm,hair is put into curlers and the reducing agent ammonium thioglycolate is added. The disulfide bonds break and keratin molecules are now free to move around and adjust to the shape of the curl. Then a 鈥昻eutralizer,鈥?such as hydrogen peroxide, is added to reverse the effect of the reducing agent. New disulfide bonds form so the keratin molecules are locked into the shape of the curls.
