Sparse Hairs Below Frontal Hairline Are Early Sign of Androgenetic Alopecia in Men

Sparse hairs below the frontal hairline in men may be an early sign of androgenetic alopecia, according to a study by the Department of Dermatology at Samsung Medical Center in South Korea. The study found that some men with sparse hairs below the frontal hairline later developed androgenetic alopecia. The researchers suggest that this finding could be used to diagnose androgenetic alopecia earlier. Androgenetic alopecia is a common hair disorder in men, characterized by recession of the frontal hairline and balding of the scalp vertex.
