  • RU58841, also known as PSK-3841, is a nonsteroidal antiandrogen (NSAA) compound that is primarily used in experimental research related to hair loss. It was developed as a topical treatment for androgenetic alopecia, a common form of hair loss in both men and women.RU58841 works by binding to the androgen receptors in the hair follicles and blocking the effects of dihydrotestosterone (DHT), a hormone associated with hair loss. By inhibiting the binding of DHT to the receptors, RU58841 aims to prevent the miniaturization of hair follicles and promote hair growth.
