If your son got the curly hair gene, this is a great cut for him. Have the stylist leave hair a little longer than normal all over. This way the curls have a little more length to work with so they're a little more loose and not so tight. Right after washing his hair, while it's still wet, put in a flexible hold mousse or gel to define the curls and give them a little more style. If left to air dry, curls can grow to great heights with lots of frizz. A little styling product keeps them under control all day.
