Haircutting, Styling, and Chemical Services
Cutting and styling foundations
Haircutting relies on sectioning, elevation, distribution, and a stable guide. A blunt cut uses zero elevation; graduated layers build weight; uniform layers use consistent elevation. Clipper-over-comb and shear-over-comb create blends and fades. Always establish the perimeter and guide first, then cross-check the balance. Styling uses blow-drying, thermal tools, and product to finish the shape; heat protection and tool temperature matter, especially on fine or chemically treated hair.
Chemical services
Chemical services require a patch test and strand test according to product directions. Color formulation depends on the color wheel, developer strength, and the client’s starting level. Relaxers process new growth only; overlapping relaxer onto previously relaxed hair causes breakage. Neutralizing is a chemical step, not a rinse-only step, and must follow the manufacturer’s timing. Never mix products unless the manufacturer allows it.
Worked example
A client wants a relaxer retouch after eight weeks. The barber should apply product only to the new growth, avoid overlapping the previously relaxed mid-shaft and ends, and protect the scalp according to the product label. After processing, the barber rinses thoroughly and neutralizes for the full instructed time, then checks that the relaxer is fully neutralized before conditioning. Applying relaxer scalp-to-end would risk overlap and breakage.
Traps
Skipping a patch test, guessing developer volume, and overlapping relaxer are major mark-losers. Do not color over metallic dyes or incompatible products without manufacturer guidance. Do not promise a result that the hair’s condition cannot support.
