Evaluating human hair luster is important in developing effective hair care products. Many methods of measuring human hair luster have been proposed, but most have major disadvantages: some require cutting the subject's hair, some utilize bulky equipment, and some take much time. A device that does not impose excessive burden on the subject and hair, but can easily and conveniently measure human hair luster, has not yet been developed. Overcoming the disadvantages of the traditional method, our new device can measure luster accurately without cutting the hair. Neither the subject's hairstyle nor its color influences the measurements. The device is small, and the time required for measurement is only 0.2 sec. The hair of 84 subjects was evaluated using this device, and there was a high correlation between the sensory score and the measurements obtained.
评估人类头发的光泽度对于开发有效的护发产品至关重要。人们已经提出了许多测量人类头发光泽度的方法，但大多数都有主要缺点：有些需要剪掉受试者的头发，有些使用笨重的设备，有些则需要花费大量时间。尚未开发出一种既不会给受试者和头发带来过多负担，又能轻松方便地测量人类头发光泽度的设备。我们的新设备克服了传统方法的缺点，无需剪发就能准确测量光泽度。受试者的发型和发色都不会影响测量结果。该设备体积小，测量所需时间仅为0.2秒。使用该设备对84名受试者的头发进行了评估，感官评分与测量结果之间存在高度相关性。
