Until a few years ago the diagnosis of hair shaft disorders was based on light microscopy or scanning electron microscopy on plucked or cut samples of hair. Dermatoscopy is a new fast, noninvasive, and cost-efficient technique for easy in-office diagnosis of all hair shaft abnormalities including conditions such as pili trianguli and canaliculi that are not recognizable by examining hair shafts under the light microscope. It can also be used to identify disease limited to the eyebrows or eyelashes. Dermatoscopy allows for fast examination of the entire scalp and is very helpful to identify the affected hair shafts when the disease is focal.
直到几年前，毛发疾病的诊断还依赖于拔取或切取毛发样本进行光学显微镜或扫描电子显微镜检查。皮肤镜检查是一种新的快速、非侵入性、成本效益高的技术，可轻松在办公室诊断所有毛发异常，包括在光镜下无法识别的三角发和发内导管等情况。它还可用于识别仅限于眉毛或睫毛的疾病。皮肤镜检查可快速检查整个头皮，当疾病呈局灶性时，有助于识别受影响的毛发。
