5 / 5 resultscommunity Finally, some real breakthroughs. A comparison of the two leading baldness treatments: PP405 versus ABS-201
PP405 and ABS-201 are promising treatments for male pattern baldness. PP405 shows rapid hair growth in human trials, while ABS-201 shows significant regrowth in animal studies but is still in early human trials.
community Everything you ever wanted to know about Pelage Pharma's PP405: how it works and what to expect
PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.
community What's going on with hmi115? The Phase 2 was concluded Nov2024 but no news
Hmi115, a prolactin receptor blocker, showed promise for hair growth, but results from Phase 2 trials have not been published. ABS-201, an AI-based analog, is expected to begin trials in December 2025, while commercialization of treatments like PP-405 is anticipated around 2027.
community Prolactin the Cause of Hair Loss? ABS-201 the Cure?
Prolactin may contribute to hair loss, but targeting its receptor won't cure androgenetic alopecia. ABS-201 could be a useful alternative or adjuvant therapy, similar to JAK inhibitors, but not more effective than HMI-115.
