Middle Part and Blending Projections by Section
A course on cutting long, wavy hair using the "middle part" technique. Learn to blend different projections across sections to control uneven curl and build a light, cohesive form.
Result and process
About the course
Middle part is a technique for cutting long, wavy hair that solves the problem of uneven curl and uncontrolled weight - especially around the nape and behind the ears. This course shows you how to work with intention when balancing different projections across separate sections, turning "difficult", flat-at-the-root hair into a cohesive, light form that naturally falls back or parts down the middle, without relying on excess product.
Kacper Trzaskowski guides you through the entire process, starting with an analysis of the uneven curl and head shape that dictates the sectioning. You'll see why the nape needs a high projection (around 160 degrees) for lightness, why the mid-back is cut in a circle for a smooth blend into the sides, and why the sides themselves are cut in a square layer (90 degrees) as the sweet spot between weight and lightness. This is a craft in blending different geometries into one cohesive haircut.
In this course you'll see
- A deliberate split of the back of the head into 5 separate sections - when and why a problematic nape needs to be treated on its own.
- Working with a high projection (around 160 degrees) at the nape to add lightness and lift the curl where the hair is heaviest.
- Building a square layer (90 degrees) on the sides as the "sweet spot" - a technique that lets you comb the hair back without building up weight behind the ear.
- Creating a circle shape on the mid-back to smoothly connect it to the square form of the sides without creating unwanted corners.
- Cutting the top into a triangle shape (from the longest fringe to the shortest back) for maximum styling versatility.
- Blending the top with the sides without adding weight - why continuing the square layer works better here than the classic "pull everything up" approach.
- The full diffuser styling process, which draws out and defines the natural curl rather than forcing it.
After this course, you'll start treating every section of the head as its own task, choosing the right projection and shape for each one. You'll stop fighting the natural curl and instead learn to control and enhance it through proper form-building. This course is for barbers and hairdressers who want to create light, wearable, versatile haircuts for their clients on long hair - haircuts that look great long after they leave the salon.

Before you start
This course assumes you already have:
What's inside
Full access with the course
0:5701Identifying the problem - weight at the nape
Looking at the back, I can see a lot of weight building up right at the nape.
6:2002High projection to create lightness
I try to lift this hair to a projection of around one hundred sixty degrees, so quite high.
12:1703Controlling the cut with the comb
It's the comb that has to set the line of your cut, not your fingers, because fingers are crooked.
17:3104Disconnection between layers for structure
I try to create a bit of disconnection between the layers, because it gives me more structure.
22:4805Choosing a technique for the sides
In this case I'll go with something very close to graduation - I'll do the square layer technique.
36:4606Cutting the top into a circle shape
That's why I'll create a circle here, because I don't want to add more weight to the sides.
46:4407Blending the top with the side
I'll blend the top with the side the same way, so I'll keep working in the square layer.
1:00:4608Thinning the sideburns for better styling
I tilt the head and very gently thin out these sideburns.
