    TLDR DHT stops hair regrowth in mice, similar to human hair loss.
    This study found that dihydrotestosterone (DHT) inhibits hair regrowth in mice by activating the androgen receptor, which is similar to androgenetic alopecia (AGA) in humans. The study suggests that targeting the androgen receptor could be a potential treatment for AGA. The study also developed a mouse model that mimics human AGA. The drug bicalutamide partially reverses the effect of DHT. The study found that DHT can cause hair loss in mice by activating androgen receptors in hair follicles, inhibiting hair regrowth.
