Aqueous Extract of Red Deer Antler Promotes Hair Growth by Regulating the Hair Cycle and Cell Proliferation in Hair Follicles

In the 2014 study, researchers explored the impact of red deer antler aqueous extract on hair growth in male mice. The study involved two experimental groups of nine mice each, which received subcutaneous injections of the extract prepared at different temperatures (4°C and 100°C), and a control group that received water. After a 10-day treatment period, the researchers observed that mice treated with the extract had an extended anagen phase, which is the active growth phase of hair, and a significant increase in cell proliferation within the hair follicles, as indicated by the number of BrdU-incorporated cells. These findings suggest that the red deer antler extract can promote hair growth by prolonging the growth phase and enhancing cell proliferation in the hair follicles.
