    TLDR Hair damage increases significantly with higher temperatures and longer heating times.
    The study used atomic force microscopy (AFM) and friction force microscopy (FFM) to analyze the topography and frictional force of Asian black male and female hair cuticles. It found that hair surfaces were damaged and modified at different temperatures and heating times. Specifically, female hair exposed to a blowing temperature of 60°C for 2 minutes showed a height between the cuticle edge and surface of approximately 440–556 nm. The study also observed that while the cuticle structures did not vary post-heating, the extent of hair damage increased significantly with more severe deterioration.
