He just let nature take its course and buzzes it every so often. I can respect that. He's always had bad hair though. The reason I got on these forums was that I realized one day how bizarre my hairline looked one day and believed I was going bald. Turned out all I had was some temple recession and my hairline had probably just moved up a bit. No mid scalp or crown thinning, thankfully (for now). A year later, and my hairline still looks the same. If anything, it may have slightly improved (can't completely confirm that; I'm only talking 1/8-1/16 inch maybe).
I'm still on this forum because I like to help guys in their teens and early twenties with NW1.5s(what I have)-NW2s who may or may not have legitimate concern over their hair. Essentially the same kind of stress I have. This community is also generally pretty nice and probably the most helpful; a lot of others are depressing, toxic, or just plain awful. Also, in case my hair decides to take a turn for the worse, plenty of advice from experienced users in treatments here.
From my profile pic (that is what I really look like) I look like I have a lot of hair (still do) and don't even look like I have any hair loss because my hair is long and covering a tiny temple point where I have had some minor recession.
