PP405 Topical Hair Gel is a topical scalp serum designed to support healthier-looking hair density, follicle activity, and scalp vitality. PP405 is an investigational hair-support compound being studied for its potential to reactivate dormant hair follicle stem cells by targeting follicle metabolism. Rather than working through traditional hormone-blocking pathways, PP405 is associated with a metabolic signaling approach that may help encourage resting follicles to re-enter a more active growth phase.
In research settings, PP405 has been explored for its potential role in androgenetic alopecia and other forms of hair thinning by targeting the metabolic state of the hair follicle. Its proposed mechanism involves inhibition of the mitochondrial pyruvate carrier pathway, which may shift follicle stem-cell metabolism toward increased lactate/glycolytic activity — a process associated with hair follicle activation and regeneration.
Potential applications of PP405 hair growth support research include:
