The square technique

The square cut technique on longer men’s hair is a fundamental method for creating a masculine style that preserves length while removing weight and correcting flat areas of the head. The course demonstrates how to create a light, dynamic hairstyle with distinct structure and natural movement on hair that falls flat and creates unwanted weight, addressing the needs of clients who want to grow their hair out.

Michał Lewiński guides you step by step through the entire layered haircut process: from precisely dividing the head into sections, to building the shape at the back by directing each strand toward the one before it, all the way to seamlessly blending the back with the sides and creating volume on top. The course emphasizes conscious work with body posture—how maintaining a single position and checking the mirror become the key to symmetry on both sides of the head.

In this course, you'll learn:

• Building a square shape step by step, with each section layered over the one below—the foundation of a symmetrical cut on longer hair.
• A precise division of the head into three key sections (back, sides, top) based on the anatomy of the skull and the mastoid process.
• Using body posture as a tool – why standing still and checking your form in the mirror are key to maintaining symmetry.
• A smooth transition of length from the back to the sides and a deliberate shaping of the corner that defines the square shape of the hairstyle.
• Customization and texturizing using a thinning shears to add lightness and remove bulk without cutting the hair shorter.
• Style your hair for a natural, relaxed look using a diffuser and bobby pins to lift the hair at the roots, without the stiff, overly styled look.
• Cross-checking – how to check your work by combing the hair in the opposite direction (vertical cut, horizontal check).

After this course, you’ll be able to work confidently with longer men’s hair, transforming the classic square cut into a tool for sculpting shape and adding volume. You’ll understand how body posture affects cutting precision and learn to create light, naturally falling hairstyles for clients who want to keep their length but get rid of the problem of flat, heavy hair.
