The post is about mice and I'm not as interested in Cedrol as about the point about anagen causing the skin to darken.
How many have noticed regrowth corresponding to a darkening of skin color?
The more autophagy you have the darker your skin will be.(study about that if I can find it).

Effects of cedrol on hair regeneration
Hair growth is controlled by a unique dynamic cycle comprising growth (anagen), regression (catagen) and rest (telogen) phases.25,26 Hair follicles remodel themselves repeatedly throughout adult life.27 It is generally known that the human hair cycle lasts several years; in contrast, the mouse hair cycle is only three weeks. The hair cycle in mice is similar to that of humans. Therefore, to evaluate the hair-growth conditions, C57BL/6 mice were selected and the production of pigmentation was taken as evidence during only the anagen phase.28,29
Hair growth was observed from the denuded area of C57BL/6 mice. The skin color of C57BL/6 mice in the telogen phase was pink, which darkens along with anagen initiation and then becomes grey.
In comparison with the application of the control, blackened skin areas, especially in the cedrol cream group, were observed 7 d after shaving (Fig. 2a). At 11 d, the cedrol cream-treated group was covered with hair in the shaved skin, whereas other groups showed relatively less hair growth. Macroscopic assessment and alopecia score (Table 2) showed that cedrol cream significantly stimulated hair growth. The scores at 6 d and 8 d were estimated to be 1.9 and 2.8, respectively. The results for cedrol ethanol were almost the same as those for minoxidil.
