Can one of you smarty pants explain the PP405 results? Why did they choose to highlight that 31% had 20% increase in density? What about the other 69%? What about other ±% in density? Why is this considered a great result? Thanks. 11/16/2025
PP405 shows promise in reactivating dormant hair follicles, with 31% of users experiencing a 20% increase in hair density in a short period. It may work faster than minoxidil and without side effects, but its long-term effectiveness is still uncertain.

Hair follicles are mostly dormant but can be reactivated with treatments like minoxidil, finasteride, and microneedling. A new drug, PP405, shows promise for hair regrowth but may not be available until 2027-2028.
community Pelage PP405: New Hair Growth from Inactive Follicular Units - Phase 2a results at AAD 2026
PP405, a topical treatment, shows promise for hair growth by activating inactive follicles, with 66% of participants experiencing positive results. The treatment is well-tolerated and may proceed directly to Phase 3 trials, offering a potential alternative to minoxidil and finasteride.
community Story time! The Great Unbalding (PP405)
PP405 is a promising new hair loss treatment that may reactivate dormant hair follicles without side effects. It could surpass traditional treatments like minoxidil and finasteride if successful in further trials.
community Why PP405 may not be dead just yet
PP405 shows promise in reactivating dormant hair follicles, with early trials indicating some success, but it is not yet a proven treatment for hair loss. Users are advised to be cautious with unverified versions, and further research is needed to confirm its effectiveness compared to treatments like minoxidil and finasteride.
community We already know how to permanently fix hair loss. The science is done. The only thing missing is the funding to run one experiment.
A permanent hair loss solution could involve reprogramming hair follicles to resist DHT using mRNA and siRNA. However, high costs, safety concerns, and the pharmaceutical industry's preference for ongoing treatments over one-time cures are major obstacles, with finasteride and minoxidil remaining standard treatments.
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.
