How long does a hair transplant procedure take? A hair transplant procedure typically takes 4 to 8 hours.

learn Stemoxydine

chemical from L'Oreal that encourages hair to enter growth phase

learn Platelet-Rich Plasma

growth factors taken from your blood and injected into your scalp to stimulate hair

What is Platelet-Derived Growth Factor Beta Polypeptide, and how does it help 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.

learn Bimatoprost

Can a lash-growth serum like bimatoprost actually work for your scalp? Bimatoprost (Latisse) is approved for eyelashes, not the scalp; two Allergan phase 2 trials in men with androgenetic alopecia posted results to ClinicalTrials.gov but were never published in a peer-reviewed journal, so scalp use remains off-label and experimental.
