Guys don't get compliments. Id almost bet my pretty hair that your interaction with him is something he still thinks about sometimes.

I love when people call my long hair pretty. Bonus points of you follow it up by complimenting my beard

Honestly... we're not hugely used to compliments on average so I'm sure he appreciated it and maybe even still remembers and recounts it to this day!

I try to keep my longer hair pretty but the curse of many a man's hairline is slowly visiting upon mine crown. T_T

An ex called me beautiful and it was obviously very memorable as evidenced by my still remembering it. Another said I have amazing, seductive-lady-in-a-makeup-commercial eyelashes (but mostly only on one eye). That one was less moving, but still funny/nice-ish/I didn't totally hate it. I just mean you might be surprised. Most guys won't be picky about compliments. We're like parched flowers.

I love it when people say my hair is pretty, makes my whole day better! Recently, it happened twice in the same week and I'm still riding those feels!
