RU-58841 (also known as PSK-3841 or HMR-3841) is a nonsteroidal antiandrogen (NSAA) which was previously investigated for use as a topical treatment for acne, androgenetic alopecia, and hirsutism. The compound is similar in structure to RU-58642 but contains a different side-chain.
RU58841 is used for the treatment of hair loss dwindled, perhaps due more to commercial potential and chemical stability reasons than efficacy as the later studies of RU58841 powder have focused on different chemical forms of the drug and combining it with various nanoparticles to enhance delivery.

Function:
RU58841 powder is the drug for the treatment of hair loss dwindled, If it is used on the scalp, by effectively inactivating DHT receptors, RU58841 should be able to stop the miniaturization of the hair follicles seen with ongoing exposure to DHT, and therefore reduce or stop androgenetic alopecia.
It is specifically designed as a topical treatment.

Application Area:
1. Increase cellular proliferation of outer root sheeth cells.
2. Increase hair diameter and hair density.
3. Increase the percentage of hair in the anagen phase.
4. Exert no negative effect on body hormone levels.
5. Provide equivalent or better net growth than Finasteride.
