Methods of hair loss evaluation: a comparison of TrichoScan(®) with the modified wash test.

The reliability of the methods currently used for diagnosing hair loss is ill defined. We studied 41 subjects complaining of hair loss, including androgenetic alopecia and telogen effluvium, and compared the results obtained with the modified wash test (MWT) and TrichoScan(®) . Data were analysed statistically with the t-test and the Cohen κ statistic.

Frontal fibrosing alopecia.

Two cases of frontal fibrosing alopecia in post menopausal women, one of them biopsy-proven, are reported. Both women showed a progressive marginal alopecia and none had multifocal areas of involvement typical of lichen planopilaris nor the mucosal or cutaneous lesions of lichen planus. However, scalp biopsy specimens from the frontal hair margin showed perifollicular fibrosis and lymphocytic inflammation.
