learn Latanoprost
glaucoma medication with hair follicle stimulant effects
- How does latanoprost work to make eyelashes and possibly scalp hair grow? Studies report that latanoprost, a prostaglandin analog, lengthens the anagen (growth) phase of hair follicles, which is the mechanism given for the eyelash thickening seen in glaucoma patients; on the scalp the evidence is one 16-man pilot study and animal work, so the effect there is unproven.
- Can latanoprost be safely applied to the scalp, or is it only for eyelashes? Latanoprost is not approved for use on the scalp and its safety there has not been established: the only human scalp evidence is one 24-week pilot trial in 16 men, and clinicians flag irritation, skin darkening and unknown absorption over a large area as open risks.
- Is latanoprost more effective for hair regrowth than minoxidil? No trial has compared latanoprost and minoxidil head to head. Minoxidil has large randomized trials and FDA approval for hair loss, while latanoprost's scalp evidence is a single 24-week pilot in 16 men, so the published evidence does not support latanoprost being the more effective option.
