learn KY19382

Experimental compound that activates hair-growth signals, tested only in animals

learn Hair Fibers

cosmetic product that temporarily makes hair appear thicker

learn Osteopontin

Signalling protein studied in hair-growth research

learn Clascoterone

How long does it take for clascoterone to show results on hair growth? Clascoterone is not approved for hair loss; it is investigational. In the trials reported so far, application was twice daily and increases in terminal hair count were reported at around 6 months, with more sustained change reported between 6 and 12 months.

learn Platelet-Rich Plasma

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.
Are PRP (platelet-rich plasma) results permanent, or does hair loss return once treatment stops? Long-term data are scarce. In one small trial, 4 of 20 men had progressive hair loss again 12 months after PRP, and PRP does not change the underlying cause of pattern hair loss.

learn Botox

How does Botox target the tension that may be blocking your hair growth? Botox for hair loss is experimental and off-label: one small open-label pilot study of 50 men reported an 18% hair-count increase, but there is no placebo-controlled trial and the proposed scalp blood-flow mechanism has never been measured in patients.

learn Caffeine

Does caffeine stimulate hair growth or only slow hair loss? Caffeine stimulates hair follicles in laboratory cultures, and one open-label trial in 210 men found a 0.2% caffeine topical non-inferior to minoxidil 5% on an anagen-ratio endpoint. A 2025 systematic review found only a few small controlled trials, mostly rated low or very low quality, and none in alopecia areata.
