The 2 block hairstyle is what you get when you cross the Undercut (quiff) with an old-fashioned Asian bowl-cut hairstyle. The sides are cut razor short just as with a undercut, but the crown area is left longer to leave some variation of the bowl.
The bowl can then be styled by being fringed, swept, layered, slicked, or even naturally messed. This cut has roared on to the scene and is a go-to style for good reason as it goes well with the properties of Asian Hair and facial features. It is versatile, clean (due to the clean sides), and is easy to maintain.
You can use different hair products to style the many iterations of the hairstyle. Browse below when going in for a haircut.
