Cathay General Hospital dermatologist Wu Min-chi states that every month he comes across two or three of these sort of cases. In the past they were mostly people who had been dying their gray hair black, but recently he's begun to see young patients.
國泰醫院皮膚科醫師吳敏綺表示，每個月都會碰到二、三個這樣的病例，過去都是頭髮染黑的中老年人比較多，最近也開始出現年輕病人。
