The thioglycolic acid in the perm solution reduces the disulfide cystine bonds in the cortex of the hair. [2] In a sense, the thioglycolate removes crosslinks. After washing, the hair is treated with a mild solution of hydrogen peroxide, which oxidizes the cysteines back to cystine. These new chemical bonds impart the structural rigidity ...

A permanent wave, commonly called a perm or permanent (sometimes called a "curly perm" to distinguish it from a "straight perm"), [1] is a hairstyle consisting of waves or curls set into the hair. The curls may last a number of months, hence the name.
The relaxer cream breaks down the chemical bonds of the hair shaft, disrupting the elliptical shape and reconstructing the bonds in a different way. Though hair follicles themselves are not damaged, the hair can become very brittle and break off. There is also risk of scalp burns if the relaxer comes into contact with the skin.
The looser curls are then set on perm rods and a chemical solution is then added to the hair to permanently curl it. "Perming" is time and labor-intensive, and expensive to maintain. The chemicals required for the process often cause the wearer's natural hair to become brittle and dry.
The hair tends to look moist and as locks. A digital perm makes the wave most prominent when the hair is dry, and loose when it is wet. Therefore, the dry and curly look of the curl iron or the hot curler can be created. Digital perms thermally recondition the hair, [citation needed] though the chemicals and processing are similar to a straight ...
