A curved-edge flat iron has rounded housing and plate edges that let it smooth hair or guide a bend and wave without the hard crease of a square-bodied tool. It still uses heat, so begin with clean, dry hair, heat protection, and the lowest effective temperature. The first picks are genuine rounded or curl-capable stylers; wide straighteners are deliberately separated where their plate width makes them less suitable for wrapped waves.

Buying tips
- Use heat protectant and start with the lowest effective temperature for your hair.
- For a soft wave, rotate the iron gradually while moving continuously instead of pausing at one point.
- A 1-inch rounded tool is generally more manoeuvrable for waves than a two-inch straightener.
