3. Hair can be reshaped into curls or straightened in a process called "perming". One way this is done is by treating hair with a chemical called ammonium thioglycolate, which is a reducing agent, followed by wrapping the the hair around a curler or ironed out straight by flatirons. After the hair has been reshaped it is treated with an oxidizing agent to stabilize the new shape. What amino acids are these chemical treatments affecting and how do they allow hair to be reshaped?
