3 Best 1/2 Inch Curling Irons 2021 – Buyer’s Guide

Curly blond hair

Explore the world of natural curls with ½ or 0.50-inch curling iron. It is the most suitable curling iron for every hair length because it is not small nor big. Natural curls are not the same all over the head. Thus, this is the staple curling iron for the curly-haired people when you just want to tame a few and don’t want to do the complete head.

It can create retro ringlets, sensuous spiral to springy curls depending on how thin or thick sections you take. However, it doesn’t volumize your hair so blow dry first if you need to add volume and then do the curls. Run your fingers through the curls. It will loosen up the curls into more natural waves and add more body. Can’t get tight kinky corkscrew curls with this barrel but can fashion well-defined spirals.

What it does?

  • It can create many styles with a different length of hair.
  • It can create bouncy curls for short to shoulder length hair.
  • Well-defined spirals on medium to long hair.
  • Will create spirals of different size on longer hair.

It doesn’t matter if you curl occasionally or regularly, this is the perfect barrel size for every length and type of hair. The thin or thicker section will give you a variety of natural curls too well-defined waves.

This is the best ½ inch curling iron for straight silky, fine/thin hair. Those who complain that curls don’t last on their poker-straight hair should try this one out! It has a professional power to give you long-lasting lively curls but gently, without damaging your delicate tresses. Only a specialized tool such as this can be trusted for damage-free styling on this type of hair.

The 24k gold barrel heats up right away and evenly which eliminates hair damaging hotspots. Patented pulse technology prevents heat fluctuation for smooth and even salon standard uniform curls. Always check the instructions for your particular hair type in the manual before you starting curling and using the recommended heat.

It’s safe to start with the lowest setting and then gradually go up. Although it can go up to 430°F, but for straight silky fine/thin hair 200°F is good enough. Silky fine hairs are too delicate so do practice caution. For the best result always curl away from the face and close to roots. The multi-heat settings let you control the heat for your particular needs.

Spring clamps help your silky hair from slipping away while long tangle-free swivel cord, extra-long cool tip, and comfortable grip help you handle the curling iron better. This excellent curling iron is available in the following sizes to cater to all your styling needs.

2. Infiniti Pro by Conair Nano Tourmaline Ceramic Curling Iron

INFINITIPRO BY CONAIR Nano Tourmaline Ceramic Curling Iron, 3/4-inch Curling Iron

Check on Amazon

Best for: Straight to wavy, normal, medium (not too thick nor thin) hair


  • 24-hour curl control
  • Tourmaline Ceramic technology for less damage and fast results
  • 395°F/202°C highest heat setting for long-lasting curls
  • Uniform heat recovery system maintains ultra-high temperature levels

  • LED temperature control

This hair type is the most perfect for different styles. But over-styling may damage your lovely locks. To form lasting curls medium hair needs more heat, but repetitive exposure to harsh heat will destroy its luster and soon your hair will be dull, damaged and lifeless. Thus, to avoid dry and frizzy hair, we suggest the Infiniti Pro by Conair Nano Tourmaline Ceramic ½-Inch curling Iron.

In ordinary curling iron, heat penetrates the hair shaft from outside reaching slowly to the center. For this reason, the surface of the hair takes the maximum heat exposure for longer and gets damaged. Ceramic releases far-infrared heat starting at the center working on hair from inside out. Thus, the natural moisture of the hair remains unharmed and tourmaline emits negative ions to lock the hair cuticle to make your hair softer, frizz-free and shinier. It will give you lasting voluminous curls while keeping your hair healthy and hydrated.
