照片是一种非侵入性技术，通过该技术，在头皮的相同精确区域上，可以识别每根头发，并确定其当前的生长阶段。这项技术被用来研究头发周期的持续时间在10名男性受试者，秃头和非秃头，在8-14年的时间内，每月的间隔观察。累积的数据用于表征这些受试者中的老化效应：毛发生长的持续时间和毛干的直径减少，最明显的是在最厚的毛发中;毛发，以及分离休止期毛发损失和生长期替代毛发出现的间隔延长。头皮毛发老化的这些不同方面有助于其渐进的整体再生。它们类似于在男性型脱发过程中观察到的那些，尽管它们的发展不那么明显。
The phototrichogram is a non-invasive technique by which, on the same precise area of the scalp, each individual hair may be identified, and its current growth phase established. This technique was used to study the duration of hair cycles in 10 male subjects, balding and non-balding, by observations at monthly intervals over a period of 8-14 years. The accumulated data served to characterize the effects of ageing in these subjects: a reduction in the duration of hair growth and in the diameter of hair shafts, most evident in the thickest; hairs, and a prolongation of the interval separating the loss of a hair in telogen and the emergence of a replacement hair in anagen. These various aspects of ageing of scalp hair contribute to its progressive overall impoverishment. They resemble those observed in the course of male-pattern balding, although their development is less marked.
