There’s an old joke about two barbers in the same shop, one with a nice haircut and one with a nasty haircut.
The punchline is barbers cut each other’s hair, so the barber with the bad haircut is the one you want.
my experience is different.
Look at the barber or hair stylist’s hair. If you don’t like their hair style, avoid. They think it looks good and will subtlety do things to make your head of hair look like theirs. Bowl cut, mullet, shaved up the side, bangs, etc.
