In my opinion if a man is good-looking/handsome, then he is good-looking/handsome with or without hair.  If he is plain/ugly with hair, he will be plain/ugly without hair.  Hair isn´t such a feature with men as it is with women.  Actually, I think beautiful women can look great with no hair too - Sinead O´Connor for example - but I don´t know if a man would agree.

And some men are tought to have more appeal with his aging (Example: Sean Connery)

Many critics and fans alike have said that the quality of his acting has only improved with age. Certainly his personal appeal has. In 1989, at almost 60 years of age he was voted People Magazine´s "Sexiest Man Alive." When advised of the award, Sean seemed to be unaffected as he replied, "Well there aren´t many sexy dead men, are there."
