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.
Ultrasound imaging can non-invasively detect active and inactive hair follicles, inflammation, and fibrosis, potentially reducing unnecessary biopsies. It may help assess hair growth potential and diagnose scalp issues, but some users believe in trying treatments regardless of ultrasound results.
HMI-115, a newly discovered hair loss treatment that could potentially be effective for those with diffuse thinning and telogen effluvium. It is based on prolactin receptor antagonist signaling and has already undergone Phase I trials in women, with potential commercialization by 2027.
PP405 shows significantly better early-stage hair regrowth results compared to minoxidil and finasteride, with 31% of users experiencing over 20% density increase in 4–8 weeks. Minoxidil and finasteride show minimal or no visible regrowth in the same timeframe.
PP405 shows promise in stimulating new terminal hair growth by activating dormant follicles, with no systemic adverse effects observed in a short-term trial. However, long-term efficacy remains unproven, and further trials are needed to confirm its potential as a hair loss treatment.
