Layer technique

The square-layer technique is a precise layering method designed to remove excess weight and bulk from the hair without shortening its length. The course demonstrates how to create a shape based on square geometry on long, thick hair—forming five deliberate corners at the head’s curves. The result is a hairstyle that retains its length but gains lightness, movement, and dynamism, solving the problem of a “heavy nape.”

Marek Krzyminski guides you through the entire process, starting with the fundamental principle of dividing the head along angle bisectors—precise lines that determine the position of each of the five corners of the hairstyle. Step by step, he demonstrates how to maintain a consistent 90-degree angle and control the shape in two planes: vertically using the cutting line and horizontally through the “two-to-one, three-to-two” rotational separation system. This is a workshop on consciously working with the geometry of the head, not merely replicating movements.

In this course, you'll learn:

• Dividing the head based on angle bisectors – how to find the points where the skull curves and determine the sections where the corners will form
• A "two-to-one, three-to-two" sectioning rotation system for creating a flat shape on the round surface of the head
• How to check the correctness of the rotation by observing the "triangle" under your hand and the sharpness of the cut line in the mirror
• Why a 90-degree projection is crucial for a square—and how to avoid accidentally adding bulk (gradation) or cutting too much weight (circular shape)
• Working on the outer side of the hand and keeping the chest perpendicular to the cutting line are essential for proper technique
• A complete styling routine using a diffuser and hair clips to shape, restyle, and mimic the natural drying process of the hair
• Finish the outer line with a Chinese knife to maintain a balance between the internal movement and a cohesive line at the neck

After this course, you’ll start consciously using the head’s geometry to create predictable shapes and angles. The square-layer technique will allow you to offer clients with long, heavy hair a solution that preserves their favorite length while adding lightness, volume, and movement to the style. Instead of randomly “layering,” you’ll begin to sculpt the form with full control over the hair’s weight and movement.
