Haircutting and Styling
This domain tests geometry: reference points, sectioning, elevation, guide selection, and how tension and tools change the finished shape.
Reference points and sections
Parietal ridge, occipital bone, apex, and the four corners anchor every design. Sections may be horizontal, vertical, diagonal, or pivoting; the section you take determines the line you cut.
Elevation changes the result
- 0° - solid form, one length, no layering.
- 45° - graduated, stacked volume, shorter at the perimeter.
- 90° - uniform layers.
- 180° - long layers, length retained at the perimeter. A stationary guide stays fixed; a traveling guide moves with each section and lets length build gradually.
Tension and texturizing
Even tension matters because wet hair stretches; cutting wet and finishing dry can shorten the result. Thinning shears remove bulk without removing length - use them in the final third of the strand, never at the scalp on top of the head, or the surface looks patchy.
Worked example
A client requests a graduated bob - close at the nape, volume higher up. Cut the nape with a horizontal section at 0°, then elevate each following section to 45° using a traveling guide so every layer is slightly longer than the one beneath it. Cutting those sections at 90° would remove the weight line the client wants.
Heat styling
Match temperature to texture: lower settings for fine or chemically treated hair, moderate for medium, higher for coarse. Always use a heat protectant, keep the tool moving, and never clamp over damp hair.
Traps that cost marks
Cutting past the guideline, over-directing hair into the wrong position, cutting the nape hairline too high, and thinning the crown.
