Hair Styling, Waving, and Thermal Services
Wet styling
Blow-drying builds volume or smoothness depending on tension and airflow: direct air down the shaft for smooth, against the natural fall for lift. Rollers and pin curls use three parts: base, stem, and curl. Base placement controls volume, with on-base for maximum lift, half-base for moderate, and off-base for minimum. Pin curls must be wound in opposite directions on opposite sides of the head to keep symmetry, and hair must be completely dry before brushing out. Finger waves need a consistent ridge direction and comb angle; the C shape comes from the comb, not the fingers.
Thermal tools
Thermal irons, pressing combs, and hot rollers must match temperature to texture: fine or lightened hair takes low heat, coarse resistant hair takes more. Test an iron on tissue paper or a strand first, always use a heat protectant, and never press damp hair or hair that was just relaxed. Barrel size changes curl diameter, not curl length; the direction of the wrap controls the base.
Traps
The classic trap is applying thermal tools to chemically damaged or freshly relaxed hair, causing burns and breakage. Another is believing heat alone sets a curl: the curl must cool on its base before it holds. A third is removing rollers or pin curls before the hair is dry, which destroys the set.
Rule of thumb
Fine, color-treated hair needing body: medium-hot rollers on damp, protected hair, dried fully, cooled in place, then brushed through, with no pressing comb.
