Only bald heads can fully express the meaning of these difficult tattoos…

It’s a two-faced person

“Your skull is made of bricks.”

It’s okay to have a full face tattoo like this

Intellectual head

Must have some hair to suit

When I bow my face means I’m thinking

Looking at it from afar, it looks like someone’s hair is actually a tattoo

The brain is a mixed item

Trouble from behind
Devil
