The high pH of these chemicals allows to open the cuticle scales and to enter the hair fibers. They respond with keratin as these chemicals interacted with the cortex to split and rearrange the disulfide bridges to stretch them out, thereby giving you straight hair.
Although this procedure does more harm than hair smoothing, even the curliest of hair can be straightened and is permanent. Therefore, the hair implemented remains straight until the natural hair grows out. Permanent hair straightening is also referred to as ‘Japanese straightening.’
