If it's a boy, I suggest you try a perm. Emphasize to the barber that the shape of the back of the head is deliberately removed. This is very simple, as long as it is fluffy. Now many Korean boys are very handsome! There are many styles of perm for men. You can go to the barber's to see their pictures and listen to the barber's advice before making a choice. When you sleep, it will flatten out. Just get up in the morning and grab the shape twice with your hands.
Just don't cut your hair too short in the future. Too short will leak!
If you don't like a lot of curly hair, you can try tin foil perm. In short, there are many ways to barbershop! Don't lose heart, this is not a shortcoming, it will be very handsome if you get rid of it a little!
I'm happy to answer your question. I wish you health and happiness!
