September 2024 in “Skin Research and Technology” This study used atomic force microscopy to identify significant morphological differences in hair from patients with lichen planopilaris compared to healthy controls, noting more scratches, uneven edges, and pitted scales in affected hair, which may aid future research on the condition.
February 2024 in “Medicina” In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.
In this study, a polyphenol and biotin supplement improved skin roughness and significantly reduced hair shedding, but did not demonstrate clear superiority over placebo in overall skin outcomes.
April 2023 in “Han'gug miyong haghoeji/Journal of the Korean society of cosmetology” This study compared the effects of direct heat perms and softening heat perms on hair, analyzing damage and morphological changes to understand their impact on hair fibers and provide foundational data for future research.
January 2005 in “Chinese Journal of Veterinary” This study observed that hairless mice of different strains initially grow hair but soon develop alopecia and other skin and pigmentation changes with age.
