buy a small straightening iron off amazon and thinning(shear) scissors along with got2b glue, thin the front then use the straightening iron to give it a slight curl then lock it in with the glue

alternatively you can use regular scissors and thin out the front bangs such that it creates a V-shape like quattro's and then use your hands to shape the side curls then glue it in

there's a lot of leniency for his hairstyle if you're wearing the sunglasses. I've seen quattro cosplayers before and they don't even bother with cutting anything, so the super super cheap alternative method is just get the glue, partition the hair in two, then glue it in
