While hair dryers and brushes can style your hair any way you want, it’s hard to beat the sleek tresses curling irons can make. Two top brands you can look into include Bio Ionic and T3. Both enjoy a loyal customer base who vouch for what these tools can do. For Bio Ionic, the Bio Ionic Long Barrel Curling Iron is one of the most recommended options. Meanwhile, long-time T3 users rate the T3 Micro Professional Curling Iron high in beauty must-haves. Below, we break down each curling iron’s design and features to help you decide.
Bio Ionic vs T3 Curling Iron Comparison Chart
The T3 curling iron has a sleeker look compared to the Bio Ionic.
Design-wise, Bio Ionic’s curling iron doesn’t draw too much attention. The Long Barrel model sports a matte finish that lends it an appliance-esque aesthetic. For its size, the model boasts a 6.5-inch barrel that offers plenty of real estate, especially if you have waist-length hair. Meanwhile, the lower end of the unit connects to a nine-foot power cord, with an integrated hook near the base for hanging the device.
T3’s 1.25-inch curling iron, one of three sizes in its lineup, has a more eye-catching design. Although it’s available in two colors, the White variant brandishes a luxe look and feel. In this model, the T3 Logo, along with the barrel and SmartTwist dial at the end of the barrel, feature rose gold accents. And since it’s buttonless, the curling iron has a seamless and minimalist form.
With the Bio Ionic, you’ll find three buttons below the thumb grip — two for adjusting the heat and one for power. To its left, you’ll see clearly marked temperature levels. Because of its location, the buttons can be accidentally pressed while using the unit. Bio Ionic solves this problem by adding a lock feature you can access by pressing the power button twice.
You won’t have similar issues on T3’s Professional Curling Iron. You switch on the unit by simply turning its SmartTwist dial. A similar action allows you to change the heat settings, too. Unlike the Bio Ionic, however, T3’s curling iron doesn’t label the temperature. Instead, you get light indicators with corresponding temperature levels you need to read from the user manual.
Bio Ionic’s curling iron has innovative features that lock in moisture in your hair. Meanwhile, T3’s styling tool is designed to create defined curls in a single pass.
Bio Ionic shares that its curling iron’s barrel is infused with what it calls Nano Ionic MX. According to the brand, the technology “micronizes water molecule so moisture can penetrate the hair.” The result is more conditioned locks 50% faster to style. Meanwhile, Bio Ionic Moisturizing Heat Technology locks in the moisture by keeping heat even.
Reviewers say the curling iron’s extra-long barrel does a great job for those with naturally long tresses and even people with hair extensions. More barrel surface area allows for quicker curls, with results that last for days.
T3’s Professional Curling Iron has a fancy-termed feature, too. The styling tool relies on an internal microchip, called Digital T3 SinglePass, that “controls temperature fluctuations and maintains even heat” in the barrel. As its name describes, the technology ensures longer-lasting results when styling your hair, even on a single pass.
Fans of this T3 clip iron share that the unit is perfect for creating defined curls. And with the SinglePass technology, the product can optimize temperatures suited to your hair type.
In terms of heat settings, the Bio Ionic model offers six, ranging from 250ºF to 430°F. Meanwhile, the T3 Micro has a temperature range of 260ºF to 410°F.
Pairing and Pricing
Bio Ionic’s curling iron is more affordable than T3’s.
While curling irons are great on their own, you can style your hair further with several other tools. Bio Ionic, for instance, recommends pairing its Long Barrel with its PowerLight Pro Dryer. If you want to add cascading curls to your look, you can also get the StyleWinder Rotating Styling Iron.
On the other hand, T3 suggests pairing its Micro Professional Curling Iron with its extensive lineup of hair brushes and hair dryers. The T3 Volume 3 round brush, for instance, is perfect for shaping your tresses while blow drying.
As for value, the Bio Ionic curling iron retails for $149.99. With Klarna, you can purchase the unit in four $37.25 installments. Meanwhile, the T3 curling iron costs $169.99. But like Bio Ionic, the Micro Professional Curling Iron is available in four interest-free payments of $42.50 using AfterPay.
