The Skullet Haircut preset isolates the style's defining contrast: an extremely short top and sides with unmistakably long hair at the back. Use the preview to judge rear length, transition placement, and how much scalp exposure you want without confusing the result with a layered mullet or fade. What makes a haircut a skullet? A skullet combines a shaved or closely buzzed top and sides with deliberately long hair left at the back. How is a skullet different from a mullet? A mullet usually keeps visible volume and layers on top, while a skullet removes nearly all top length to create a much sharper contrast.
