Morphological Analysis of Hair Before and After Rebonding Using Scanning Electron Microscopy (SEM)

This study investigates the morphological changes in hair before and after undergoing a rebonding treatment using Scanning Electron Microscopy (SEM). The research involved a comparative analysis of one strand of healthy, untreated hair and one strand of post-rebonding hair from a female subject. The SEM images revealed that the untreated hair had tightly arranged and smooth cuticle scales, whereas the rebonded hair exhibited surface erosion and cracks in the cuticle. These findings demonstrate that rebonding causes significant damage to the hair cuticle, highlighting the need for developing protective post-rebonding hair care products.
