What is an undercut haircut?
Undercut haircut — is a contrasting hairstyle in which the temples and back of the head are shaved or cut short, and long strands remain on the crown and crown.
The main technical feature of this cut is the absence of a smooth transition (fade) between short and long hair. The boundary between the lengths, known in hairdressing as a "disconnection," remains sharp and clearly defined.

Historically, this haircut emerged in the early 20th century. It gained popularity among the military and the working class due to its practicality and ease of maintenance. The undercut has returned to modern fashion as a universal, gender-neutral trend that easily adapts to a variety of appearances.
The main types of undercuts
The classic cut features a medium-length crown, combed straight back or to the side. This style works best on straight or slightly wavy hair that holds its shape well.

The textured undercut (or grunge version) features strands of varying lengths on the crown. The hair is styled in a deliberately casual style, creating a voluminous and relaxed silhouette.
An undercut with a shaved part (hard part) is an extreme version with maximum contrast. The dividing line between the short and long sections is further emphasized by a thin shaved strip.
A women's undercut is often achieved with a hidden shave. The hairstylist trims the length only at one temple or at the nape of the neck. Long hair can completely cover the shaved area when worn loose or accentuate it in updos.
How to wear and style
For a sleek, business-ready look paired with classic suits and shirts, opt for a sleek hairstyle. The strands are combed back with a pomade or gel with a subtle, glossy sheen.

Casual, smart-casual, and streetwear looks, including leather jackets, denim, and basic T-shirts, require a different approach to styling. For these styles, a matte clay or paste is used to create pronounced texture and volume without the appearance of a stuck-on look.

Maintaining the shape requires regular salon visits. The haircut requires touch-ups every two to three weeks to maintain the sharp contrast in lengths and the neatness of the closely shaved areas.
