Inhibitory activities of some traditional Chinese herbs against testosterone 5α-reductase and effects of Cacumen platycladi on hair re-growth in testosterone-treated mice

TLDR Certain Chinese herbs, especially Cacumen platycladi, can promote hair regrowth and reduce hair loss-related hormone levels in mice.
In the 2016 study, traditional Chinese herbs, particularly Cacumen platycladi (CP-ext), were found to inhibit 5α-reductase (5αR), an enzyme that converts testosterone to dihydrotestosterone (DHT), a key factor in androgenic alopecia (AGA). CP-ext significantly promoted hair regrowth in testosterone-treated mice by shortening the time for skin darkening, increasing hair length, and altering the hair follicle cycle. It also reduced DHT levels in the skin and down-regulated 5αR expression without affecting serum androgen levels. The study, which included a sample size of 5 for histological data and 8 for androgen level measurements, suggests CP-ext has potential as a natural treatment for AGA, warranting further research to understand the active substances and mechanisms involved.
