I recently bought this Conair 3/4″ (19mm) Instant Heat Spiral Iron on a whim when I was checking out the makeup and hair aisles at my nearby CVS drug store. I hadn’t tried one of these spiral irons before, so I was curious how my hair would turn out if I used it. This Conair iron heats up in 30 seconds and has 25 heat settings (low 1-8 for thin hair, medium 9-14 for average to thick/treated hair, medium-high 15-20 for thick or wavy hair, high 21-25 for hard-to-curl hair, and a turbo heat setting for up to 20°C/36°F burst of heat for difficult styling spots).
The above picture on the right shows how hair wraps around the spiral iron starting from the bottom (clamp the end of the strand first) and then goes between the grooves as you turn the iron. It takes some practice to get used to turning the iron and getting your hair in the right place, but once you get used to it, this spiral iron makes some pretty nice curls — especially for only ~$16! I’ve found that once you align your hair within the first groove, the rest falls in place much easier as you turn the iron clockwise.
Here’s the finished product of my first attempt using this spiral iron. I sprayed some heat protection spray right before curling, and then I used Bumble and Bumble Does It All Spray to set it. The curls lasted the whole day, and it looked more like natural curls the next morning!
