TLDR Bleaching and combing damage hair's surface and mechanical properties.
The study demonstrated that chemical (bleaching) and mechanical (combing) treatments significantly altered the nanoscale surface properties of human hair, including surface roughness, mechanical stiffness, adhesion properties, and surface potential. These changes were consistent with previously observed effects at the macroscopic fiber-level scale, as shown through advanced imaging modes of atomic force microscopy.
