Bio Ionic OnePass Straightening Iron Review [Updated for 2022]

When you see the Bio Ionic OnePass Straightening Iron, what’s the first question that pops up in your mind? If you’re like most people, you’d want to know why it’s called one pass.

According to the manufacturer, this model was created to cut down on the time it takes to straighten the hair using a flat iron.

The unit comes with Silicon Speed Strips, which is stationed on the 1.5-inch wide plates on the unit.

It is responsible for increasing the rate at which the hair is processed once it passes through the flat iron.

To many people, the silicone strips help them grip the hair better and provides a smooth pass. A result is soft, silky and shiny hair.

However, a few people have complained that the strips come out after a few months, which is sad. This is the goal of the maker. And that seems to be coming to fruition.

Bio Ionic Onepass Straightening Iron Review

In the case of this unit, the above is true. There are currently about 400 reviews on the product, with the positive reviews taking as much as 70%. This shows that a lot of users are happy with their purchase.

We’ve reviewed a lot of products and honestly, not a lot of products rate this highly. The props go to the Bio Ionic Straightening Iron.


The heating elements are positioned in the ceramic plates of the unit itself, which makes for quick heat-up times. The heat generated is infrared, which is hair-friendly. It doesn’t burn hair or cause damage like ultraviolet rays.

The maximum heat level is 400F with instant recovery. This ensures you get smooth results and a few breaks aren’t going to have any effect on your styling.

Furthermore, the variable multi-heat makes adjusting temperature stress-free. Thus, it can be used on a variety of hair types.

For convenience, the Bio Ionic Straightening Iron comes with a 10ft power cord. This is attached to the base of the flat iron by way of a swivel. Also, it’s long and thus makes steering the unit simple and smooth.

Quick heat up

People like that it warms up quickly and the adjustable temperature was invaluable. When it heats up in a minute or less, it increases efficiency, which is very helpful for busy divas.

Get professional results

It’s interesting to note that many people stated that their stylist recommended, sing the praise of the One pass, or that they’ve seen a salon use one.

If you’re looking for the same results as the professional hairstylists, this may be a good time to get the right tool. Even if you’ve been styling hair for years, if you don’t have the right tools, it may be difficult to get good results.

Is it truly “one pass”?

The argument on one pass is quite a subject. While some users find the manufacturer’s chosen name to be true, others prefer to refer to it as ‘two pass’. However, the most important thing is that it works.

As long as it doesn’t leave your hair brittle, dry or damaged, it has achieved its aim. Besides, it can be one pass for you, even though many are claiming that it isn’t the case.

I see this more as a personal thing. Previous experience, usage, hair type may affect the result. So one pass may not be positive for a beginner. But a pro with flat irons can get good results the first try.

Drawbacks but not deal breakers

On the other side of the coin, we’ve found a few drawbacks with the unit. Compared to other flat irons, the unit is expensive. However, there is a unanimous agreement that it returns good value for money.

While there are a lot of people praising it for the reliability, many others state that it stopped working after a time.

Granted, everyone will want to get a few years of service between the unit die on them, especially after paying such an amount to buy.

The good thing is that the reports are not overly gloomy. There are also a lot of cheerful reports, especially on performance.

It’s lightweight

While it’s not a mini flat iron, The Bio Ionic Straightening Iron is light and as a result, is easy to wield. Many users appreciate the small size and lightweight of the unit, which also makes it easy to pack for travel.
