Yesterday I have started using minoxidil, but I am not sure I understood the prescription thoroughly. It says that you shouldn't wash your hair 2 hours after using it. Does it mean that after this period I can shower or go for a running? or I have to wash my hair before any sport activity whatsoever? I am asking this because I put minox in the morning and before sleep, but in the evening/late morning I go to the gym (sweat), thus I'm afraid the substance will drip with the sweat.
