Best hair flat irons

Start with the ghd Platinum+ styler. One temperature, but it's the one that suits nearly everyone: fine, medium and thick hair, straight through coily, and it's the most consistently well-rated iron here. It's the safest pick if you don't want to think about heat settings.

Who the others suit:

• Dyson Airstrait — if you want to dry and straighten in one pass, and you're nervous about heat damage.
• T3 Single Pass Smooth X — long or fine hair; the extra-long plates cover more hair per pass.
• StyleQ Flat Iron — thick or coarse hair that needs real heat control (titanium, 12 settings).
• NuMe Megastar — very thick, frizzy hair; wide plates and high heat.
• Remington Shine Therapy — a solid everyday iron on a tight budget.
• TYMO SWAY — travel and quick touch-ups; heats in seconds and runs on dual voltage.

Skip the straightening brushes if you want a true pin-straight finish — they smooth rather than flatten.
