TLDR Greying hairs may be protected from alopecia areata.
The document described a case of patchy alopecia areata that notably spared greying hairs within the lesional areas. This phenomenon suggested a potential protective effect of the greying process against the autoimmune attack typically seen in alopecia areata. The case was reported by Cheng Tan, Wen-Yuan Zhu, and Zhong Sheng Min from the Department of Dermatology at the First Affiliated Hospital of Nanjing University of TCM and Nanjing Medical University in China. The findings contributed to the understanding of hair pigmentation's role in alopecia areata.
