Hair is looking good bro! When you've been on minoxidil for a while the hair sheds and cycles all together, so i think that is what you are seeing with regards to the shedding and also why you have not lost ground. Confidence does matter, but so does hair. you are a fairly handsome guy with enough hair at your age to work with you so you dont suffer romantically. I dont think you have anything to worry about hairwise.
