My anecdata is pretty limited. I didn't have a professional haircut until the age of 15 - my mother insisted on cutting my hair. There's a reason why I don't let anyone see childhood photos of me unless they've signed an NDA first.
I didn't have a professional haircut until I was 22, I think. Shrug.
I also haven't had one in at least 10 years so if the coffee thing is relatively recent that'll be why. Or I just went to cheap hairdressers.
