RU58841 topical solution

RU58841 topical solution used for androgenetic alopecia (male/female pattern hair loss).

Hair follicles in genetically susceptible people are sensitive to DHT (dihydrotestosterone) and other androgens. DHT binds androgen receptors in scalp follicles and gradually causes:

• follicle miniaturization
• shorter growth cycles
• thinner hairs
• progressive hair loss

RU58841 works by blocking androgen receptors locally in the scalp. It competes with DHT at the receptor level, reducing the signal that drives miniaturization. Unlike finasteride/dutasteride, it does not primarily reduce DHT production—it blocks DHT action where applied
