PP405, a topical LDH inhibitor, has shown to stimulate hair follicle stem cell proliferation in humans with moderate hair loss. They are advancing to more detailed trials this year.
PP405 is a potential hair loss treatment that inhibits mitochondrial pyruvate carriers, increasing lactate dehydrogenase activity and stimulating hair follicle stem cells. In a phase 1 trial, 31% of participants showed over 20% hair density increase with PP405 treatment.
PP405 from Everychem is likely fake and potentially harmful, with concerns about its stability and the risk of using the wrong MPC inhibitor, which could damage hair follicles. The real PP405 was studied under strict conditions, and DIY attempts are discouraged due to unknown formulation and quality control.
PP405 is discussed as a potential alternative to finasteride, but its effectiveness and market availability are uncertain. Users share experiences with finasteride, minoxidil, and topical treatments, noting side effects and application techniques.
