Tbh I don't mind bald men at all (actually they're kind of sexy...) but there's nothing I hate more than ****ty combovers and similar tricks. They don't fool anyone and they just look sad.
I'm aware that men often are super self conscious about receding hairlines but I think there's way too much stigma against lack of hair, both in men and (especially) women. Some people just naturally lose their hair after a certain age and there's nothing wrong with that...
But hey, maybe I'm just biased because my dad has always been bald (at least, since before I can remember), so what do I know XD
