Hairstyling and Finishing
Wet styling versus thermal styling
Wet styling (rollers, pin curls, air forming) sets hair through hydrogen bonds and requires the hair to dry completely before it is disturbed. Thermal styling (blow dryer, curling iron, flat iron) temporarily reshapes hair with heat; the set lasts until moisture or heat resets it.
Roller bases, stems, and curls
Every roller set has three parts: the base (where the roller sits), the stem (hair between scalp and roller), and the curl (hair around the roller). Base placement controls volume:
- No-base - roller sits off its base, smooth, least volume.
- Half-base - moderate volume.
- On-base - roller sits directly on its base, maximum volume and fullness.
- Off-base - roller sits below the base, smooth and flat.
Pin curls follow the same logic: flat curls sit close to the head, standing curls sit on base for volume, barrel curls use the full stem for a strong end curl.
Heat and finishing
Choose temperature by texture and condition: fine, lightened, or damaged hair needs lower heat than coarse, resistant hair. Always use a heat protectant, keep tools moving, and never apply a hot iron to wet hair. Backcombing builds volume at the scalp; backbrushing is gentler. Finish with light, even product - too much weighs the set down.
Traps to expect
On-base versus off-base is the single most tested distinction. Another trap is claiming a thermal set is permanent - it is temporary until moisture or heat returns.
Worked example
A bride wants a smooth chignon with no root lift. Rule of thumb: volume is a function of base placement - choose off-base or no-base sets, not on-base.
