Slick back with undercut: what it is, who it suits and what to tell your barber

Slick back with undercut is a medium-length cut listed under men's cuts in the FitMyFace catalog. The catalog describes it this way: all the hair combed straight back off the forehead with a light shine, sides clipped short and tapered above the ears, top about 10 cm lying flat towards the back; any longer hair is cut short, so no hair falls forward, over the ears or past the jaw.

Who it suits

The catalog lists oval, square, diamond and long (oblong) face shapes as suiting the slick back with undercut. It marks heart-shaped faces as a weaker fit for this cut.

For an oval face: Balanced proportions: most cuts work, so pick for your lifestyle. For a square face: Soften a strong jaw with texture, layers and movement. For a diamond face: Soften the cheekbones; add width at forehead and chin.

The catalog pictures it on straight hair. The catalog says a stylist can usually cut it on straight and wavy hair, and leaves curly and coily hair off that list, so ask a stylist who works with your texture.

FitMyFace hair previews are approximations, not predictions of how your hair will lie after a cut. Ordinary hairstyle try-ons perform face analysis on-device. The optional AI previews (hair and glasses) send a photo to Cloudflare; your consent is the one "I agree" on the scan screen, and a switch on the results turns them off.
