Why go home and immediately take a shower? I go to places that wash my hair after my cut so I don’t have to go home and shower.
In my experience, no matter how careful anyone is, I now have sharp, freshly-cut hair bits under my shirt. Unless I take my shirt off and wipe my body with a towel, no amount of post-cut washing of my head is going to solve the problem.
What kind of barbers do you go to? I have been going to a barber for 23 years and not once in my life did I have this problem
Do you get your hair buzzed? The only place those back of neck small hairs can go is down.
