Hair presentation test

A woman, aged 20 years, presented with a seven-year history of progressive asymptomatic hair loss that developed initially on her eyebrows and then progressed to also involve her scalp.There was no relevant past medical or family history and no regular medications.Multiple previous dermatologists had diagnosed either alopecia areata or female pattern hair loss, but the pattern of the hair loss was inconsistent with either diagnosis.The areas of hair loss changed slowly over weeks to months, with some areas extending and others improving.Clinical examination showed multiple broken hairs of variable length with no actual baldness.On trichoscopic examination, there was no inflammation, hair miniaturisation or exclamation mark hairs (Figure 1).
