[Analysis Case] Observation of Hair Surface Microstructure by AFM

Quantitative evaluation with reduced alteration is possible through analysis in the atmosphere.

This case study introduces an analysis of the condition of the cuticle on the hair surface using AFM. AFM is a method for three-dimensional measurement of nanoscale surface roughness. Since the analysis is conducted in the atmosphere, it does not cause degradation or gas release of organic materials, allowing for an evaluation of the sample's original shape. In this case study, we assessed the degree of cuticle opening, the distribution of adhered substances, and the roughness evaluation of different areas through images, as well as quantitatively evaluated the surface roughness through numerical processing. This method is effective for evaluating the condition of hair after shampooing and the application state after applying styling products.
