Scientists successfully created and transplanted bioengineered hair follicles that function like natural ones, suggesting a new treatment for hair loss.
Hair follicles usually go dormant rather than die, and treatments like finasteride, minoxidil, and hormone therapy can sometimes reactivate them, though results vary. Complete regrowth is rare, especially in long-term bald areas, but some individuals see significant improvement with these treatments.
PP405 shows promise in hair regrowth, with 31% of participants experiencing over 20% increase in hair density after 8 weeks. Phase 3 trials are expected in 2026, with potential market availability by 2029-2031.
PP405 may reactivate dormant hair follicles but won't replace hair transplants or resurrect dead follicles. Its effectiveness, cost, and impact compared to treatments like minoxidil and finasteride are uncertain.
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.
