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.
Finasteride and minoxidil can revive hair dormant for up to 7 years, with microneedling enhancing regrowth. Users report significant hair regrowth even after long periods of baldness.
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.
Minoxidil alone is often insufficient for treating hair loss because it doesn't address the DHT-related cause. Combining it with finasteride, a DHT blocker, is generally more effective.
