Ring of Hair
Sometimes, people with hypertrichosis have something referred to as a hair collar. The hair collar is a ring of hair that is darker and coarser than surrounding hair. It is localized, meaning that it appears in a specific area.
This abnormal hair pattern is found around skin that's different from surrounding skin. The hair overgrowth is long, very thick and usually dark, also known as terminal hair.4Chien, Mu-Ming, et al. ‘The Hair-Collar Sign.’ The Journal of Pediatrics, vol. 168, 2016, p. 246, doi.org/10.1016/j.jpeds.2015.09.081
