How long is the efficacy of it? Thanks
In general, minoxidil needs to remain on the scalp at least 6 hours.
Sweat can reduce absorption and penetration into the skin.
It is unlikely that minoxidil on the scalp would run down to irritate the eyes. But if you experience this or have specific concerns be sure to speak to your dermatologist and pharmacist.
