The Bio Ionic One Pass Straightener


The Bio Ionic One Pass hair straightener is Bio Ionic's flagship flat iron. As such, it incorporates top notch technology and all the best features that you need a hair straightener to have today. Using this straightener is easily one of the best ways to improve the results of your hair styling regime.

Features of Bio Ionic One Pass

The Bio Ionic One Pass has a number of features that not only make it a great straightener, but help it stand out from products like the GHD. Here, Bio Ionic has created a product that differs from a GHD in a few key ways:

  • Temperature control
  • Nano particle plates
  • Ionic straightening
  • Far infrared heating
  • One pass straightening
  • Silicone strips
  • 5 second heat up
  • Extra long 10ft cable (1.5 inch plate design)
  • 5 year warranty

Bio Ionic One Pass vs GHD

The GHD company started out with a phenomenal product, back when straightener technology was less advanced and hair straighteners weren't so widespread. However, GHD hasn't kept up with the times and has neglected to incorporate any of the latest technological advancements into their recent straighteners. GHD relies on brand hype to sell.

One of the biggest drawbacks to buying a GHD is that GHD straighteners don't have temperature control and they have shown a stubborn refusal to implement such a feature. This leaves their straighteners stuck at the maximum temperature.

The actual plates used for a GHD straightener are even more basic, incorporating plain ceramic technology without utilizing the nano particles made possible by recent nanotechnology advances, and not even using tourmaline ceramic plates, which have become the successor to the original ceramic plate.


Temperature control

A higher temperature, when used on hair that is fine, fragile, or has been colored or lightened, is excessive. So excessive in fact, that it actually causes damage to the hair. The heat can only be turned up so high before any extra straightening benefit ceases and damage just becomes more likely.

Because the Bio Ionic One Pass can be adjusted to a temperature that suits your own hair type, the temperature can be modified to a setting is far less damaging to your hair and still produces the best results. This also means that you can share it with other people and they can choose their own temperature, and that when you're styling someone else's hair you're able to choose the right temperature for their hair.

All of this makes the Bio Ionic One Pass a less damaging straightener for use on anyone's hair, and that's without even factoring in the other features that reduce damage and improve the straightening results.

Plate technology

The plate technology used in the Bio Ionic One Pass is truly the pinnacle of flat iron technology because it features natural mineral nanoparticles. These mineral particles are smaller than microscopic and are the latest product made possible through cutting edge nanotechnology.

At this size range, arranging materials in the right order can produce novel materials where the nanoparticles are small enough to assert quantum effects. In the case of the One Pass straightener, Bio Ionic has built nanoparticles into their plates in a way that more beneficial negative ions are produced during straightening than is possible with a ceramic or even tourmaline plates.

These negative ions smooth the hair, breaking up particles of water into individual molecules and pushing them into the hair shaft where they condition the hair where it's needed most. The cuticles are sealed shut, locking in all this moisture as the One Pass moves through the hair, leaving your hair feeling soft, smooth, and straight.

The nanoparticles incorporated into the plates also produce more far infrared energy than other plates. Far infrared waves heat and straighten the hair much more effectively than other wavelengths of infrared energy. This leads to smoother hair than is possible with a straightener that doesn't have this functionality.

All of this is finished off with the addition of the silicone speed strips, creating a non-stick surface that glides through the hair, preventing tearing or snagging, and speeding up the straightener's movement through the hair. In most cases, as the name suggests, a single pass through a section of hair is all you need with the Bio Ionic One Pass.


Other features

The Bio Ionic One Pass has a little more functionality to include here after looking at the plates. The power cable, for one, is exceptionally long. This means that the straightener is well adapted to be used anywhere in the room, even when a power outlet isn't nearby. In the salon, the benefit of movement is even clearer.

On top of this, the Bio Ionic One Pass takes a mere 5 seconds to heat up, making it the fastest straightener available. Throw in Bio Ionic's generous 5 year warranty, which is more than twice as long as GHD's warranty, and you have a straightener of the absolute highest quality. Bio Ionic is obviously so proud of their product that they're willing to bet it will last well up to 5 years.

Using your Bio Ionic One Pass

To get the most out of your Bio Ionic One Pass, and any straightener in general, you need to actually section your hair out while you straighten it. Taken handfuls of hair isn't the most methodical method of straightening hair and it doesn't lead to the best results because the hair isn't flat when you pass over it with the straightener.

For the best straighten and smoothest finish when using a hair straightener, section out hair with sectioning clips and comb each thin layer out before passing over it with the straightener. Repeat this process until all your hair is straightened and you'll end up with perfectly straightened hair.

Heat protector

Heat protector is another important factor in your hair straightening regimen, and even when using a straightener like the Bio Ionic which allows you to choose a temperature that minimizes damage, you should still be using a product that protects your hair from the heat.

Heat protectors include products like hair serums and straightening sprays which protect your hair from the damaging effect of the heat, whilst helping to ensure a smoother finish. Hair serums, in particular, are one of the best ways to combat frizz, as well as prevent dryness and add shine to your hair. Use them both before and after using your Bio Ionic One Pass and your hair will look phenomenal.

If you're looking for the best hair straightener available, and you don't want to spend a huge amount of money, you're in luck, because the One Pass is quite affordable compared to other brands. This is because whilst Bio Ionic is the new industry leader in straightening technology, it doesn't price its products based on brand prestige, so you can buy a One Pass without breaking the bank.

No other straightener has quite the technological prowess of the One Pass, and with the long 5 year warranty on these straighteners, you can be sure your Bio Ionic straightener keeps you happy for years to come.

Exciting! With age, color, and natural "fluffiness" as adversaries, we need an instrument with intuition :)
