Flat Iron Temperature by Hair Type

Turning a flat iron to its highest setting because the hair isn't straightening is how most heat damage happens. The right temperature depends on your hair, and it is usually lower than people assume. Super Kelly Beauty on Gratiot near 8 Mile stocks flat irons with adjustable heat, plus the protectants that go with them.

Start low and work up

Begin at a lower setting and do one pass on a small section. If the hair straightens, that's your temperature. If it doesn't, go up one step and try again. The goal is the lowest setting that works in a single pass, because two passes at a low temperature does more damage than one pass at the right one.

Rough guides by hair type

Fine, damaged or color-treated hair generally sits at the low end of the dial. Medium, healthy hair sits in the middle. Coarse, thick or very curly hair needs the higher end to straighten in one pass. Chemically relaxed hair is more heat-sensitive than it looks and should be treated as fine rather than coarse.

Heat protectant is not optional

A protectant puts a barrier between the plate and the hair shaft and helps distribute heat rather than concentrating it. Apply to damp hair before drying, or to dry hair before ironing, and let it dry fully first, because ironing wet hair boils the water inside the shaft and causes real damage. Sprays, creams and serums all work; the one you'll actually use is the right one.

The signs you've gone too far

Hair that feels rough after ironing, ends that look see-through, curls that no longer revert after washing, and a burnt smell during styling all point to too much heat. Heat-damaged hair does not repair, it only grows out, so backing off early matters more than any treatment sold to fix it.
