Dynamics of Procollagen Type 1 N-Terminal Propeptide in Postmenopausal Osteoporosis During Bisphosphonate Therapy and Transcranial Electrical Stimulation

PTD-DBM is being explored for hair regrowth by targeting CXXC5, with clinical trials expected after pre-clinical studies. Users express anticipation and skepticism about its effectiveness.

The conversation discusses potential hair loss treatments focusing on stimulating IGF-1 at the follicle level using growth-factor cocktails and engineered peptides, such as Acetyl Tetrapeptide-3, Copper Tripeptide-1, Oligopeptide-20, Thymosin-β4, and Palmitoyl Tetrapeptide-7. It suggests that device-assisted delivery methods like microneedling may enhance effectiveness.

PP405 may promote short-term hair growth by pushing follicles into the growth phase, but concerns exist about long-term effects due to lack of rest phases. Users discuss various treatments like finasteride, minoxidil, spironolactone, alfatradiol, and investigational drugs like KX-826 and GT20029 for hair maintenance and regrowth.

Osteopontin, a protein involved in hair growth on moles, may help with hair loss. However, it is also linked to Alzheimer's, cancer, and bone development, so caution is advised.

PP405 trials have completed phase 2a, showing promising results with a 31% stat for hair density increase, and are moving directly to phase 3. Detailed results will be presented at a medical conference in 2026.

Amplifica is testing a compound called AMP-303 for hair loss, but it's not Scube3 or osteopontin. The timing for the results from the clinical trial is unknown.
