Evaluation of Surface Structure and Morphological Phenomena of Caucasian Virgin Hair with Atomic Force Microscopy

This study used Atomic Force Microscopy (AFM) to examine the surface structure and morphological changes of Caucasian virgin hair from 10 healthy volunteers. The research identified four key surface types—striated, endocuticle, smooth, and cortex—highlighting the natural delamination process of hair scales. AFM revealed variations in scale dimensions and significant changes in scale edges due to wear and tear, with more damage observed towards the hair ends. The study emphasized AFM's potential for diagnosing hair disorders by providing detailed insights into hair surface morphology and structural integrity. Limitations included the small sample size and challenges in scanning damaged hair areas.
