community PP405 Won’t Work: Follicle Is Miniaturized, Fibrosed, And Missing Key Support Cells

7 months ago

PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.

community EU Shouldn't Ban Fin & Dut: PFS is NOT REAL.

10 upvotes 1 year ago

Finasteride and Dutasteride do not cause depression or "Post Finasteride Syndrome," with concerns often linked to the nocebo effect and preexisting mental health issues. The EU is unlikely to ban these drugs, but access may become more restricted due to ongoing debates.

community Will PP405 need to be used indefinitely, like minoxidil?

31 upvotes 11 months ago

PP405 may not need daily use like minoxidil, but finasteride might still be needed to maintain hair regrowth. PP405 reawakens dormant hair follicles, potentially offering a long-term solution, though not a permanent cure.

community Everything you ever wanted to know about Pelage Pharma's PP405: how it works and what to expect

126 upvotes 3 months ago

PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.

community Potential ( but not yet confirmed ) pp405 leak through korean media.

233 upvotes 11 months ago

A peptide-based hair loss treatment, PP405, reportedly increased hair density by 62% in 90 days, but these claims are unverified and met with skepticism. Users compared PP405 to Minoxidil and Finasteride, expressing doubts about its effectiveness without more evidence.
