community Before and after PP405 from phase 2a after applying it for just 4 weeks
PP405 shows some hair growth after 4 weeks, but results are debated and expectations should be tempered. Some users compare it to minoxidil or finasteride, questioning its effectiveness and commercialization timeline.

7 / 800 results- What happens after a hair transplant? Expect mild swelling and redness, with new hair growth starting in 3 to 6 months.
- How long does a hair transplant procedure take? A hair transplant procedure typically takes 4 to 8 hours.
- How is stemoxydine proposed to affect hair growth on the scalp? Stemoxydine is a cosmetic ingredient proposed to shorten the empty phase before a new hair grows. Short L’Oréal-linked studies in men reported small density gains; independent proof is lacking.
- What is platelet-derived growth factor beta polypeptide (PDGF-BB), and does it stimulate new hair growth? PDGF-BB is a growth factor that signals to dermal papilla cells and promotes blood-vessel formation; mouse studies report it can push follicles into the growth phase, and human evidence comes only indirectly from PRP trials. No PDGF product is approved for hair restoration and there is no published human trial of PDGF-BB on its own.
- Can a lash-growth serum like bimatoprost actually work for your scalp? Bimatoprost (Latisse) is FDA-approved only for eyelashes, not the scalp. In the larger of two Allergan phase 2 scalp trials, every bimatoprost formulation gave smaller hair-count gains than minoxidil 5%; the results were posted to ClinicalTrials.gov but never published in a journal, and scalp use remains off-label and experimental.
