Further evaluation of the differential requires exclusion of other causes of hair<unk> , and assessing for the typical progressive hair<unk> <unk>  of androgenic alopecia. Trichoscopy can be used for further evaluation. Biopsy may be needed to exclude other causes of hair<unk> , and histology would demonstrate perifollicular fibrosis. The Hamilton–Norwood scale has been developed to grade androgenic alopecia in males by severity.
