TLDR The research improved understanding of hair and skin properties across different ethnicities and conditions.
The study used atomic force microscopy (AFM) to perform a comprehensive nanotribological characterization of human hair and skin, focusing on surface roughness, friction, and adhesion. It examined hair samples from different ethnicities (Caucasian, Asian, and African) and assessed the effects of damage and conditioning treatments. The findings indicated that virgin hair cuticles were relatively intact but showed mechanical damage, while damaged hair exhibited varying degrees of chemical damage and severe wear. The study highlighted the importance of understanding these properties to develop better hair care products.
