Hair Styling Tools and Techniques

Choosing the right styling tools and product quantities makes the difference between a salon-quality finish and a flat or over-loaded result. Curling iron barrel diameter determines the tightness of the curl: smaller barrels (19mm) create tight curls, while larger barrels (32-38mm) produce loose waves and body.

Blow dry time depends on hair length, density, texture and the desired finish. Fine, short hair may take 10-15 minutes, while thick, long hair can take 30-45 minutes for a smooth blow-dry. Using the correct nozzle, brush size and sectioning technique dramatically improves efficiency and the final result.

Heat protection is essential whenever using heated tools. Apply heat protectant evenly through mid-lengths and ends before blow drying, and again before using straighteners or curling irons. Most heat protectants protect up to 220°C. The amount needed varies by hair length and density — too little leaves hair vulnerable, too much makes it heavy and greasy.
