Hair straighteners for sleek, glossy hair
A hair straightener, or flat iron, smooths frizz and leaves hair sleek, straight and shiny. Modern straighteners heat up quickly and use ceramic, tourmaline or titanium plates to glide through hair evenly. Many also double as curling tools, letting you create waves and curls with a simple twist. Adjustable temperatures help you style safely, whatever your hair type.
What to look for
- Plate material: ceramic for even heat, tourmaline for shine, titanium for fast heat-up.
- Plate width: narrow for short hair and fringes, wide for long or thick hair.
- Adjustable temperature: essential for fine, coloured or damaged hair.
- Auto shut-off for peace of mind.
How to straighten your hair
- Start with clean, completely dry hair.
- Apply a heat protectant and brush through.
- Work in small sections, gliding slowly from root to tip in one pass.
- Finish with a drop of hair oil or serum for shine.
Protect your hair
Never straighten wet hair unless the tool is designed for it, avoid passing over the same section repeatedly and use the lowest effective temperature. Give your hair regular heat-free days and treat it to a weekly mask.
