PP405 may revive dormant hair follicles but is unlikely to help with long-term baldness where follicles are replaced by scar tissue. It is seen as a potential adjunct to treatments like minoxidil and finasteride, but its effectiveness on deeply fibrotic or scarred areas is doubtful.
Hair growth relies on mechanical forces, not just chemicals, with tissue acting like a motor. Minoxidil and finasteride help, but maintaining tissue elasticity and addressing mechanical issues are essential.
Exploring the idea of transplanting miniaturized hair follicles to healthier areas to potentially reverse hair loss, with concerns about DHT sensitivity and scar tissue formation. The conversation also humorously considers using mice for hair growth experiments.
GT20029 is a new hair loss treatment in Phase 3 trials in China, using PROTAC technology to target androgen receptors, potentially with fewer side effects than finasteride and minoxidil. VDPHL01, a second-generation minoxidil, is also mentioned as potentially more effective.
