Morphological Changes of Hair by Repeated Treatments of Permanent Wave

Abstract
|
|
|
|
In this study, we observed the effects of repeated perms on the morphology of virgin hair of a healthy thirteen year-old girl with scanning electron microscopy. After the first treatment, the outer parts of cuticle cell were broken unevenly and roughly. Cuticle cells were lifted upward making a space. After the third treatment, cuticle cells were lifted off one another and the folded scales showed irregular surface areas. Broken pieces of cells were stuck on the surface and an empty hole was present in the endocuticle of the cytoplasm. We observed that cortex separated from cuticle layer more easily with repeated treatments.
