From the standpoint of chemistry what is the main difference between a permanent wave and a depilatory?
Permanent Wave:
Permanent Waving is a 2-step process, the hair undergoes a physical changes caused by wrapping the hair on perm rods and then the hair under goes a chemical change caused by the application of permanent waving solution and neutralizer.Permanent Wave alters the side bonds only when done correctly.
Permanent Waving is the Adding wave or curl to hair.
The Disulfide Bonds are Strong chemical side bonds formed when the sulfur atoms in two adjacent protein chains are joined together (the strongerst of the 3 side bonds, accounting for about 1/3 of the hairs overall strength) (The chemical physical changes in disulfide bonds make permanent waving, curl-reforming and relaxing possible).
Chemical depilatory:
A painless method of hair removal that dissolved the hair at skin level.
Temporary Hair Removal mainly procedures include shaving, chemical depilatories, tweezing and waxing.Chemical depilatory removes unwanted hair by breaking down the protein and dissolving it at skin level.
