Best BIO IONIC Flat Iron Reviews

BIO IONIC OnePass Styling Iron


The OnePass Styling Iron has been a cult favorite with consumers for many years now, and it still stands strong.

The iron packs a lot of great features in just one tool, with its most striking one being the silicone speed strips on the plates.

These strips help to grip hair gently yet firmly and allow them to glide through the plates in a smooth stroke without pulling or breaking.

The plates are also infused with their NanoIonic MX™ technology, which uses negative ions to break down water molecules into really tiny particles and helps them enter the hair shaft. 

As a result, hair is moisturized and conditioned while you style it, leaving your tresses sleek and shiny with very little heat damage. The style also holds for longer without becoming frizzy.

For me, one of the best design features is that the power and temperature buttons are located on the inside, so they don’t get in the way while I am using the tool.

It’s available in two sizes, a 1” and a 1 ½”, so you can choose the most suitable width based on your hair length and needs.

One major difference between the two sizes is that the silicone strips are in the center of the plate on the 1 ½” version. This placement grips hair a bit better than the 1” one, which has silicone strips on one edge of the plate.

As the name implies, the styler claims to straighten hair in one pass, which it does quite handily for most hair types (especially finer hair).

For extra thick or coarse strands, you might need more than one pass, especially if you don’t use smaller sections at a time.


  • Ergonomic design and comfortable-to-hold matte finish
  • Temperature memory feature
  • Wide range of heat settings from 265°F to 450°F
  • Makes hair look and feel smooth and healthy
  • 5-year warranty


  • No hinge lock
  • Silicone strips accumulate build up if not cleaned regularly

BIO IONIC 10x Pro Styling Iron


The Bio Ionic 10x Pro Styling Iron is another one of Bio Ionic’s best sellers.

The most striking feature on this hair straightener is the sonic vibrating plates, which separate each strand and enhance the contact of plates with hair, enabling heat to be distributed evenly across.

(You don’t have to use the vibrating function – there’s an option to turn it on or off – but then you’d miss out on the main benefit of the 10X Pro.)

To turn on the vibration, just press the power button once while the iron is already powered on. The plates will start to vibrate when held together and you can hear a buzzing sound.

One way to confirm if the vibration feature is on or not is by looking at the digital display, which will blink while the vibration is turned on.

To turn the feature off, just press the power button once again. This is different from turning the iron off, which requires pressing and holding the power button for a few seconds.

The 10x Pro is a really versatile styling tool that can be used for curling in addition to straightening. Its outer body is sleek and rounded, giving you beautiful, voluminous curls.

The tapered tip makes it possible to get closer to your roots, and I find it really helps to tame frizz and little baby hairs that tend to stick up every which way.

It heats up in only 30 seconds, and the 9′-long swivel cord comes a velcro tape wrapped around it for compact storage.

Naturally, these advanced technological features add up to a hefty price tag, which makes it out of reach for some. See if you can score it on sale, or try getting a limited edition one (which for some reason is cheaper than the standard version – see more below).


  • Volcanic mineral-infused ceramic produces negative ions for shine
  • Optional sonic vibration feature maximizes surface contact and glide
  • Fully-adjustable heat controls up to 450°F + digital display
  • Dual voltage for worldwide use
  • Lightweight and easy to handle


  • Sometimes hair gets caught in tip, particularly thicker hair
  • Premium price tag

BIO IONIC Magical Stone 10x Pro Styling Iron Limited Edition


This is a limited edition version of the 10x Pro Styling Iron we just talked about.

With its gorgeous marbled exterior, this tool is certainly a notch above your regular flat irons and is the thing to go for if you like your appliances to make a statement. 

The design is not just visually appealing, it also feels easy to hold and makes for a comfortable grip.

Its vibrating plates glide in a smooth and swift manner and are infused with volcanic minerals that nourish hair and make your tresses shiny and sleek.

The iron produces moisturizing heat much like other Bio Ionic flat irons, which locks moisture deep into the hair shaft and reduces damage from heat styling.

The plates on this straightener are 1” wide, and it has a temperature range from 280°F to 450°F for total control over the amount of heat exposure to your strands.

There’s no functional difference between this version and the black 10x Pro, so if you’re trying to save, this one is slightly less expensive.


  • Eye-catching design
  • Digital display and controls
  • Makes hair soft and silky
  • Auto shut-off
  • Vibrating plates create extra-smooth polish and shine


  • Vibrating sound is kind of loud

BIO IONIC Flat Iron Features

Silicone Speed Strips

Silicone speed strips are unique to the Bio Ionic OnePass Styling Iron and are designed to softly grip your locks and evenly distribute them across the plates so that they glide through in a swift, buttery manner.

The strips make it possible to style hair without pulling and tugging, and ultimately the style also lasts longer.

If you’re considering the OnePass, make sure to wipe the plates down after each use as product buildup can accumulate on the strips, slowing down their efficiency.

Vibrating Plates

Vibrating plates, such as those on the Bio ionic 10x Pro Styling Iron, help to separate each individual strand as a section moves through the iron.

This allows even pressure and heat to be applied to each strand and leaves locks pin-straight without any kinks.

Users seem to have split opinions about the efficiency of the vibrating plates, with many claiming that these make all the difference and others feel they don’t do much.

I think that it all comes down to your technique.

If you take smaller sections at a time, the vibration can actually improve the texture and feel of your hair. Even with dry, damaged hair full of split ends, the result looks and feels incredibly healthy and smooth.

Plate Technology

Nearly all Bio Ionic flat irons utilize ionic technology, which means they generate negative ions to counteract positive ions in dry hair for a smooth, frizz-free style.

They also have ceramic heaters which heat quickly, and also generate consistent heat across the plate without giving rise to hot spots.

In various Bio Ionic straighteners, the plates are infused with different high-tech materials including volcanic minerals and graphene.

These mineral complexes leave hair looking and feeling healthier.

Is BIO IONIC Worth The Price? 

Bio Ionic flat irons are certainly not cheap, so you should consider one an investment in the look, feel, and health of your hair.

The company packs a lot of advanced technology in its tools, from silicone speed strips to volcanic-mineral vibrating plates, in addition to the usual ionic technology, ceramic heaters, and far-infrared heat that many flat irons have.

They are definitely effective, and manage to make even frizzy, dry strands shiny and soft.

Add to this the features I always look for – like a long swivel cord, a lightweight tool, and auto shut-off – and you pretty much have a complete package when it comes to the perfect hair straightener.

Should You Get A BIO IONIC Flat Iron?

If you can swing the cost, I wouldn’t hesitate to get one. Bio Ionic’s hair appliances are designed for high-grade performance and the effectiveness of their flat irons are second to none for producing shiny, smooth hair that looks and feels healthy.

They’re particularly good for straightening fine hair without damage but are powerful enough to tackle thick, coarse manes too.
