Cutting, Styling, and Heat Application on Alternative Hair
Cutting, Styling, and Heat Application on Alternative Hair
This domain tests controlled cutting and heat work on units, where mistakes are permanent and cannot be grown out.
Core rules
- Mount the unit on a block or the client's head as it will be worn; secure it so it cannot shift while cutting.
- Synthetic hair is usually cut dry and shaped with point cutting or slide cutting; wet-cutting can stretch or distort fiber. Human hair can be cut wet or dry, but check curl pattern and shrinkage.
- Cut inside the perimeter, not through wefts, lace, or knots. Leave a perimeter margin until the shape is confirmed.
- Heat: know the fiber's rated temperature; use thermal protectant; test a hidden strand; keep the tool moving; let the fiber cool in the desired shape.
- Synthetic fiber has memory: a curl set at high temperature becomes permanent; a bad set may not be reversible.
- Steam, rollers, and low-heat blow-drying are safer for standard synthetic; human hair tolerates higher heat and oxidative color.
- Brush synthetic gently when cool; hot fiber stretches and frizzes.
Worked example
A client wants loose waves on a standard synthetic wig. Reasoning: a 400°F iron risks melting. Use steam rollers or a low-heat (under the label limit) tool, test a hidden area, set the wave, cool fully, then brush into shape. If the fiber is not heat-rated, do not use heat.
Traps
Cutting lace or wefts while blending; using high heat "quickly"; brushing a hot curl; assuming human hair and synthetic need the same cutting tension; forgetting that thinning shears can create holes in a wefted cap.
