hahahaha that happens to me too, since the beggining of my hair loss I can't stop at others people hair (hairline, temples, crown...), it is sickening.
i have become the opposite. I will notice, but immediately look away because it's f*cking depressing as f*ck. I see these a**h** douch bags that treat their girlfriends like sh*t just walking around with thick hair that they don't even think about. If someone looks at my hair for more than three seconds I immediately say, "what the f*ck are you looking at?!?"
Pretty common, soon your gonna be calling out norwoods left and right. Saw some old man probably mid 60s long salt and peper hair still dense and nw1 the guy probably still pulls a lot of women.
