More heat is not always more effective
The goal is to use the lowest temperature that achieves the style on your hair. The right setting depends on the tool, the section size, how wet the hair is and its current condition.
Repeated passes over the same section can matter as much as the number on the tool. Follow your tool’s directions and avoid prolonged contact with one section.
Water and hot tools do not mix casually
Unless a tool is specifically designed for damp hair, use thermal irons on dry hair. For blow-drying, remove excess water gently and keep the dryer moving rather than holding concentrated heat in one place.
Make heat protection part of the system
A heat protectant is one part of a better routine, not permission to use unlimited heat. Pair product choice with lower settings, fewer passes and occasional heat-free styling days.
