A modified photometric technique has shown considerable differences between the refatting kinetics of the scalp and forehead. The refatting on the forehead occurs rapidly, probably due to the large follicular reservoir. The follicular reservoir of the scalp, which bears a large terminal hair, is much smaller and so the refatting time is longer. Thus, sebum excretion and sebum production rates probably correlate better on the scalp than on the forehead, and we suggest that the scalp may be a better site than the forehead for investigating sebaceous gland physiology.
一种改良的光度测定技术显示，头皮和前额的再脂化动力学存在显著差异。前额的再脂化迅速发生，这可能是由于毛囊储存库较大。头皮的毛囊储存库较小，其上生长着粗大的终毛，因此再脂化时间更长。因此，皮脂排泄率和皮脂生成率在头皮上的相关性可能比在前额上更好，我们认为，对于研究皮脂腺生理学而言，头皮可能是比前额更好的部位。
