Noninvasive diagnostic tools, such as Trichoscan®, reflectance confocal microscopy (RCM), and optical coherence tomography (OCT), are efficient methods of hair shaft and growth evaluation. The aim of this study was to carry out a comparative assessment of these three medical procedures by measuring the hair shaft and hair growth after hair removal for a defined period of five days. The application of these techniques was demonstrated by measuring hair growth on the lower leg of six female volunteers. After removal of the hair shaft with a shaving system, the hair follicle infundibula and the length of the growing hairs were measured with the Trichoscan®, RCM, and OCT method. All three methods are reliable hair measuring tools after hair removal. Trichoscan® is best suited in the implementation of hair growth measurement and RCM in the analysis of hair follicles, whereas the OCT system can be consulted as an additional measurement for the evaluation of the hair follicle and length.
非侵入性诊断工具，如 Trichoscan®、反射共焦显微镜 (RCM) 和光相干断层扫描 (OCT)，是评估头发和生长的有效方法。本研究的目的是通过测量脱毛后五天内的头发和生长情况，对这三种医疗程序进行比较评估。通过测量六位女性志愿者小腿上的头发生长，展示了这些技术的应用。使用剃须系统去除头发轴后，使用 Trichoscan®、RCM 和 OCT 方法测量毛囊漏斗部和生长中毛发的长度。所有三种方法在脱毛后都是可靠的毛发测量工具。Trichoscan®最适合于测量毛发生长，RCM 最适合于分析毛囊，而 OCT 系统可作为评估毛囊和长度的附加测量方法。
