TLDR White hair regrowth in alopecia areata may be more common than thought.
A 57-year-old man with a history of alopecia areata and ulcerative colitis experienced white hair regrowth in areas of previous hair loss. This case highlighted the association between alopecia areata and poliosis, a condition characterized by localized depigmentation of hair. The study reviewed literature on alopecia areata and poliosis, suggesting that poliosis may be more common in areas of previous alopecia areata-related hair loss than currently documented. The findings indicated that poliosis could be linked to various conditions, including autoimmune diseases, genetic syndromes, infections, medication use, and trauma.
