Full disclaimer: I am trying to embrace my natural curls, but my default state is still a straightening iron.

Recently, I took a good look at my trusty flat iron and saw that it was really starting to show its age. When I stopped to think about it, I realized I’d had the thing for several years without ever replacing it. Maybe it was time for an upgrade?

One quick Google search later, I kept seeing Bio Ionic’s 10X Styling Iron come up. Bio Ionic is a professional-grade hair tool brand known for its ionic and mineral technology, and its tools are designed around something the brand calls Moisturizing Heat®—the idea that heat styling doesn’t have to mean completely drying out your hair.

Naturally, I went ahead and bought the 10X Styling Iron, and I looooove it. My only regret is not waiting a few more weeks to buy it… because Bio Ionic is currently running some amazing sales. During Halloween Week from October 21-31, you can get 30% off $150+ with code TREAT30 or 35% off $200+ with code TREAT35, plus 15% off limited-edition colors.  The Mystery Gift Set will also be available with purchases of $175 or more during that promotion. And if you’ve had your eye on the Smart-X, it’s 30% off throughout October, with an even bigger 40% discount during the October 13-17 flash sale. One of the brand’s top bestsellers, the Long Barrel Curling Iron, will be 40% off during this time period, too.

Bio Ionic’s styling tools are worth the investment even at full price, but these sales are a pretty great opportunity to snag one of the brand’s top-notch tools for less. And on that note, here are five of their best-selling heat tools to keep on your radar as the sales kick off!

Long Barrel Curling Iron ($163)

Long-haired girlies, you already know the struggle of trying to wrap all your strands around a standard-size curling iron. If I were buying a curling iron today, it’d be this one, primarily because of the longer barrel. It’s also Bio Ionic’s best-selling curling iron, so clearly I’m not the only one who appreciates the extra room. The barrel is two inches longer than the average curling iron, giving you more room to work with and making it easier to style longer strands.

It’s designed to create everything from spirals and tight curls to voluminous, soft waves, so you can get plenty of mileage out of one tool. It also gets bonus points for Bio Ionic’s Ion Generating Complex, which helps condition hair as you style.

10X Styling Iron ($262)

I have long, frizz-prone hair, so I need a heat tool that gets the job done without requiring me to go over the same section of hair a million times. One of the reasons I bought this styling iron was because of its promise to make straightening my hair incredibly quick and efficient.

It delivers! The curved design and sonic vibrating plates help the iron glide smoothly through my hair while polishing each strand, and the brand’s Ion Generating Mineral Complex helps lock in moisture as I style. It heats up in just 60 seconds, too, which is a very nice feature when I’m trying to get ready quickly. Bio Ionic says it can deliver up to 50% less frizz and 50% more shine, and I can definitely see the difference. It leaves my hair looking noticeably smoother and shinier.

AeroGravity Featherlight Dryer ($299.99)

Who said getting smooth, shiny hair had to double as an upper-body workout? Because it definitely wasn’t Bio Ionic’s AeroGravity Featherlight Dryer.

I don’t love drying my hair for this exact reason, but this dryer could change my mind. Weighing under 1 pound, it’s at least 30% lighter than traditional dryers while delivering up to 40% more powerful air velocity. It also has nine customizable settings, a digital LED display and a travel-friendly design with dual voltage, so you can get salon-level styling without the heavy lifting.

Smart-X High-Efficiency Dryer + Diffuser ($359)

It’s all in the name: “high efficiency.” The Smart-X uses more air pressure and less heat to dry hair quickly, which is designed to help keep strands looking and feeling healthier. I also love that it has three speed and three heat settings that remember your preferences, so you can really customize your routine.

Because it comes with a diffuser, it’s a great option if you’re switching between straight styles and embracing your natural curls.

Twist Interchangeable Iron ($199.99)

Stuck on what kind of curls you want? Bio Ionic’s Twist Interchangeable Iron is basically three curling tools in one, so it makes that decision a whole lot easier.

It comes with a .5-inch wand for tight, spiral curls, a 1-inch tapered wand for defined, sculpted curls, and a 1.25-inch clip for relaxed, loose curls. So whether you’re in the mood for bouncy spirals or soft, undone waves, you can get there by simply switching barrels. And because the whole system is compact and portable, you can take your curl options with you wherever you’re headed.

Honestly, any of these hair tools would be a major upgrade to your routine. But you know what else is an upgrade? These deals.

Running Halloween Week October from 21-31, you’ll score savings on sitewide purchases, plus limited-edition colors and a Mystery Gift Set with qualifying orders. The Smart-X is also 30% off throughout October, with an extra-deep discount during the October 13-17 flash sale.

Here’s to better tools, better hair days, and paying a little less for both!
