heatstyling

Heatstyling refers to styling hair by applying controlled heat from appliances such as flat irons, curling irons, hot rollers, and blow dryers to alter hair's shape or texture. It is widely used to smooth, curl, or volumize hair and can be combined with products like heat protectants and styling lotions.

Mechanism and effects: The heat temporarily softens the keratin in hair and can break and reform disulfide bonds to set a new form. Repeated or high-temperature exposure can remove moisture from the cuticle and cause damage, leading to frizz, breakage, and color fading. Outcomes depend on hair type, condition, and technique.

Usage guidelines: Use the lowest effective temperature for your hair type, typically lower temps for fine or damaged hair and higher for thick or coarse hair. Always apply a heat protectant, avoid using on wet hair, dry hair thoroughly, limit passes over a section, and use a shield or ceramic heated tool for even heat. Allow hair to cool between sections.

Care and alternatives: Excessive heat can necessitate deeper conditioning and trimming; regular deep conditioning helps restore moisture. Alternatives include air-drying, low-heat styling, or chemical smoothing treatments for longer-lasting results. Proper storage and tool maintenance, such as cleaning plates and inspecting cords, can reduce the risk of uneven heating.
