double-parted hair
A hairstyle with a distinct or implied double-part along the scalp/roots of the hair, of which extends farther than a widow's peak.
A common attribute of certain hairstyles, such as pompadours, undercuts, and upright mohawks - these hairstyles greatly emphasize the parting by using differing hair volumes.
Not to be confused with double-parted bangs, which concerns the bangs rather than the hair across the scalp.
