Chemical Texture Services Practice Test

Neutralization’s job is to lock in the new shape by reforming the hair’s disulfide bonds after they’ve been broken during the waving process. The reducing step first breaks those bonds so the hair can take on a new curl or straightened form. The neutralizer then oxidizes the newly formed sulfhydryl groups back into disulfide bonds, stabilizing the curl and stopping further chemical action. This re-bridging of bonds is what keeps the hair in its new shape. The other options don’t describe this bonding reformation or the stopping of processing.
