About this look

The Grealish Slick Undercut is a medium-length world cup style that flatters oval, square face shapes.

Best on straight or wavy hair and medium maintenance — a trim about every 4 weeks keeps the shape. Most associated with the 2020s; it has stayed in rotation since.

Ask for a disconnected undercut with length on top to slick straight back.
