Straighteners split into two camps: classic hot-plate irons, now with much smarter temperature control, and Dyson's air-based Airstrait that straightens from wet. The right one depends on your hair and your patience.
Where these picks come from. This shortlist is based on the makers' published specs, the features that matter for each device type, and availability from the brand or Amazon itself. Our own instrument tests are under way; results will be added here, clearly marked. How we test · How we make money

Straightens with high-pressure airflow instead of hot plates, and works from wet hair, so it replaces your dryer and iron in one step.
ghd's newest flat iron. Its motion-responsive technology reacts to how you move the iron to keep plate temperature steady at ghd's 365°F styling temperature.
A 1-inch ceramic flat iron with 9 heat settings and longer plates, designed to straighten in a single pass.
Most hair styles well around 365°F (185°C). Higher is faster but riskier. Good irons hold a steady temperature along the whole plate instead of overshooting.
Ceramic plates heat evenly and glide; the plate length and width decide how much hair you can do per pass.
Air straighteners like the Airstrait dry and straighten at once, with no hot plates touching the hair. The finish is smooth but usually less sleek than a plate iron.
Auto shut-off and a heat-resistant tip are basics; check the cord length and swivel too.
These are the measurements we are running on every device in this guide. Results will replace the "queued" labels as they come in. Full method →
Fine or damaged hair usually needs less heat; very coarse hair more. Many professional irons default to about 365°F (185°C), which is a sensible starting point.
