research Sudden whitening of the hair in an 82-year-old woman: the ‘overnight greying’ phenomenon
An 82-year-old woman's hair turned white suddenly, likely due to a rare form of alopecia that targets pigmented hair.
research A Prospective Study of Dermoscopic and Ultrastructural Features of Vitiligo-Associated Leukotrichia
The study found that white hair in vitiligo has specific patterns and structures, which vary with the stage of the disease and may be similar to another hair condition.
research Molecular and Cellular Characterization of Avian Reticulate Scales Implies the Evo–Devo Novelty of Skin Appendages in Foot Sole
Bird foot scales develop differently and can repair but not fully regenerate due to the lack of specialized stem cell areas.
research White Hair–Induced Increased Scalp Visibility: Clinical Implications for Hair Loss Evaluation and Hair Transplantation
White hair can make the scalp look more visible, which may be mistaken for hair loss.
