thetodd's way is easiest :agree:
I do on occasion use Minoxidil without washing the Nanofibres out of my hair, you have to be really careful otherwise it'll make a horrible mess but it is doable, as long as you then wash your hair the next day at some point before applying Minoxidil (otherwise you get a build up of fibres and Minoxidil, which isn't good)
The main problem I have is that I often use DermMatch, but I can't apply Minoxidil with that on, which is a pain, have to shower twice in a day if I want to use it.
