research Morphological analysis of patchy thickening and reddish discoloration of active hair growth areas in the skin of New Zealand White rabbits
This study suggests that the patchy thickening and reddish discoloration in rabbit skin during the hair cycle may be due to large anagen-phase hair follicles compressing the dermis and increased blood vessels causing redness.
research Mechanistic synergy of hair growth promotion by the Avicennia marina extract and its active constituent (avicequinone C) in dermal papilla cells isolated from androgenic alopecia patients
In this study, researchers found that crude extracts from Avicennia marina and its component avicequinone C inhibit mechanisms contributing to androgenic alopecia in vitro, including 5α-reductase activity and DHT-AR interactions, potentially promoting hair growth and delaying the catagen phase in human dermal papilla cells.
research In vivo and in vitro evaluation of hair growth potential of Cacumen Platycladi, and GC-MS analysis of the active constituents of volatile oil
This study found that Cacumen Platycladi volatile oil promotes dermal papilla cell proliferation and enhances hair growth in mice, outperforming minoxidil and showing no obvious cytotoxic effects.
research Exosomes derived from human dermal papilla cells promote hair growth in cultured human hair follicles and augment the hair‐inductive capacity of cultured dermal papilla spheres
This study suggests that exosomes derived from dermal papilla cells, especially those cultured in three dimensions, promote hair growth and regeneration by enhancing follicular cell activity.

5 / 973 resultscommunity 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 Han Bio Aims for Phase 1 Clinical Trials in 2027 after successful hair growth in mice
Han Bio plans to start Phase 1 clinical trials for a hair growth treatment in 2027 after successful results in mice. Many users express skepticism about the effectiveness of treatments that work on mice but not on humans, and discuss existing treatments like finasteride and minoxidil.
community Can someone explain the science behind why Finasteride doesn't stop you from losing regrown hairs from minoxidil?
Finasteride prevents further hair loss by blocking DHT, while minoxidil stimulates hair growth by prolonging the active phase of hair follicles. Stopping minoxidil can lead to loss of regrown hair because finasteride does not address the same growth mechanism.
community Before and after PP405 from phase 2a after applying it for just 4 weeks
PP405 shows some hair growth after 4 weeks, but results are debated and expectations should be tempered. Some users compare it to minoxidil or finasteride, questioning its effectiveness and commercialization timeline.
community PP405: The Ultimate Hair Loss Drug for Complete Hair Growth
PP405 is a new hair loss treatment in phase 2 trials that may promote hair growth by increasing lactate production and activating hair follicle stem cells. It could potentially replace hormone-disrupting treatments like Minoxidil and finasteride.
