Why We Love the Bio Ionic Curling Iron
This curling iron is not cheap, BUT it's truly one of the BEST we've ever owned and this is the exact iron many stylists (including our hair girls) use and love. After featuring it for years, we've noticed it almost never goes on sale. Let us repeat: it NEVER goes on sale, so don't miss this, especially if you have long hair!
The Bio Ionic Curling Iron stands out for so many reasons:
- Long barrel for long hair: Curl more hair at once and finish your styling routine faster!
- Nanolonic MX technology: This innovative feature locks in moisture, leaving your hair smooth, shiny, and frizz-free.
- Customizable heat settings: Choose the perfect temperature for your hair type and protect it from damage.
- Cool-touch tip: Makes handling easy and safe while styling.
- 2-hour automatic shut off: A safety feature that is always looking out for you.
- 9ft swivel cord: More than enough length to reach any outlet. Plus it swivels with each wrap around so you don't have to worry about the cord getting tangled!
How to Use the Bio Ionic Curling Iron
Using it is super simple:
- Start with clean, dry, and brushed hair.
- Use a heat protectant. Our favorite is this smoothing and 450 degree heat protectant spray!
- Adjust the heat setting to your desired level. (We recommend never going above 400)
- And just use your favorite curling technique!
TIP: Just a few seconds in the hot iron is usually enough, but don't separate/brush through the curls until they've completely cooled to ensure long-lasting curls!
How Long Is It?
It is designed with a barrel that’s 2 inches longer than standard curling irons, making it a dream for anyone with long hair. This extra length allows you to wrap more hair around the barrel at once, which means quicker styling sessions and fewer passes needed to achieve gorgeous curls. It’s the ultimate time-saver for busy mornings or when you’re getting ready for a night out!
What Is It Made Of?
The barrel of the Bio Ionic Curling Iron is crafted with a high-quality ceramic coating infused with NanoIonic MX technology. This advanced technology works to lock in moisture, seal the hair cuticle, and leave your strands looking smoother, shinier, and healthier after every use. Unlike traditional curling irons that can strip your hair of moisture, the NanoIonic infusion actively conditions and hydrates your hair as you style, making it perfect for preventing damage and maintaining your hair's natural softness. Amazing right?
The ceramic coating ensures even heat distribution, minimizing hot spots that can cause breakage, while also delivering long-lasting curls with a glossy, polished finish. Plus, nothing beats how easily your hair glides through each curl in this iron!

Sizing Guide: Which Barrel is Best?
The 1.25-inch barrel is our go-to for creating soft, natural curls and waves. It’s the most versatile size, perfect for achieving everything from beachy waves to polished curls. But here's a visual below to see how each size curls!
