I've been seeing some posts about people who have complained about facial aging. Is this only possible if the minoxidil goes on the face? I was thinking about applying minoxidil solution (not the foam) in the morning and then making sure I stop any bad habits of touching my hair. Then in the evening to apply minoxidil 4 hours before showering so I can go to bed with a clean scalp. As long as I avoid facial contact with minoxidil I should be fine, right?
