How to Choose the Best Flat Iron
Plate width and styling precision
Plate size dictates how much hair you process in one pass. Wide options like the Remington Shine Therapy Wide with 110mm x 45mm plates and the Golden Goods Professional Steam Hair Straightener suit long or thick hair. In contrast, the Remington Hair Straightener with Extra Slim Plates features plates 45 per cent slimmer than standard models, making it ideal for short hair, bangs, beards, and bobs.
Heat technology and plate coatings
Plates feature different protective coatings and technologies. The Golden Goods Professional Steam Hair Straightener uses moisture steam technology to minimise fiber damage, which can be turned off when desired. If you prefer oil-infused plates, the Remington Shine Therapy S8500 uses Moroccan Argan Oil, while the Revlon Smoothstay Hair Straightener uses coconut oil to increase shine.
Temperature range and travel features
Heat settings vary across models to match different hair textures. The Remington S3500 offers a 30-setting variable wheel, while the BaByliss Rose Gold Hair Straightener provides 3 temperature settings from 180°C to 235°C. For travellers, both the BaByliss Rose Gold and the Remington Slim Hair Straightener S1370 feature worldwide voltage, though the S1370 operates at a single set heat of 215°C.
Selecting hair appliances over food products
Results for flat iron searches can include grocery listings such as M MARKET STREET British Flat Iron Steak 283g. Ensure you review specifications carefully so you select a dedicated styling tool like the UNOBEY Hair Straightener rather than prepacked beef grill steaks.
