TLDR Hair loss in twins may be linked to family history of hair loss, high blood pressure, heart disease, and possibly anxiety, but more research is needed.
The study "Comorbid conditions associated with androgenic alopecia: A twin study" conducted from 2016 to 2017, involved identical and fraternal twins, with a focus on those reporting a history of androgenic alopecia. The study found no significant differences in personal comorbidities between twin pairs where one twin indicated hair loss. However, anxiety approached significance in twins who noted hair loss. In twin pairs where both twins indicated a history of alopecia, there was a significant family history of hair loss, hypertension, and heart disease. Interestingly, fraternal twin pairs with a history of hair loss were more likely to have a family history of psoriasis. The study concluded that twin pair comorbidities may be individually based on environmental factors and larger twin-based studies are necessary to further evaluate prevalence of comorbid conditions and significance of family history in patients with androgenic alopecia.
