INSTYLER Thermal Straightening Brush for Hair Review

Last update: Mar 24, 2017 09:15, Anna

In this article, I will discuss and review the InStyler Thermal Hair Straightening Brush. I will point out the features, characteristics, pros and cons of this hair tool to educate you, the consumer so that you will be better informed to make a purchasing decision.

First Impressions

This hair straightening brush certainly breaks the mold as far as hair styling tools are concerned. It is white and purple with black bristles and control panel. This is definitely a welcome departure from the black body color that seems to be the norm for these types of units.

Next, it has a nice sleek, modern look about it, possessing smooth, gentle curves in the body. Overall, it looks modern and actually fun to use. It feels light yet looks quite durable.


Looks are not everything, however. Now we shall look at the design of this hair straightening brush.

The InStyler Straight Up possesses an LCD display. Immediately, this one feature indicates that the operating temperature is adjustable. I have to mention that this is a very nice feature to have because one temperature does not necessarily suit all hair types. It is nice to be able to dial in the temperature that best suits your specific hair type.

The entire body of the brush is made of plastic. The heating plates are made of ceramic. The head is oval in shape.

The dimensions of the brush are: 2.8×4.5×13 inches, and it weighs in at a nice and light one pound.

I confess that purple is my favorite color. Therefore, the fact that the heating surface is purple made this brush really catch my eye. The body is white, which provides a very clean and modern look while the bristles and control panel are black. No other body colors are available.

Oddly, there is nothing in the product’s box other than the hair straightener itself. There is not even an instruction sheet. This is okay, however, in that the operation of the unit is pretty much self-explanatory. The controls are simple. There are three buttons: on/off, temperature up, temperature down.


This brush heats up quickly. It goes from room temperature to the maximum operating temperature of 450 in 30 seconds. This is unprecedented as virtually every competing unit on the market takes at least a full minute to do this.

This brush has a rotating cord which is helpful in keeping the cord out of your way while it is in use. It does not, however, have a hanging hook. A hanging hook would make storage easier. At the same time, the back of the head stays cool while the front is hot.

Upon Further Inspection

Seven different temperature settings are offered. The operational temperature range goes from 330˚F to 450˚F.

The InStyler does feature an anti-scald design in that the bristle tips are always cool to the touch, even while the heating element is on and the brush is in use. The bristles are labeled as ionic indicating that they do feature ionic properties which are helpful in producing smoother hair after use.

The surface of the heating element is ceramic. This is the preferred heating element material because it provides for uniformity of heat across the entire surface and eliminates hot and cold spots that are characteristic of metal heating elements. This fact makes ceramic a lot more gentle for the hair and much less likely to burn or over-process it.

An essential safety feature of this unit is the automatic shutoff. I say this is essential because the unit will shut off if you happen to forget to power it down after using it. This means that risk of fire is greatly reduced.

This hair straightening brush is not dual voltage. It runs on 110-120 volts AC and so, it is designed for the North American markets. An adapter is required if the brush is to be used outside of the US and Canada.

The button layout is simple and self-explanatory. There are three buttons. One button is for turning the brush on or off. The other two buttons are for lowering or raising the operating temperature.

The Pros

This brush is visually appealing. The combination of white, purple and black is pleasing to the eye and is a nice departure from the all black coloration of most competing units.

Another great feature is that although this brush is lightweight, coming in at one pound, it certainly is durable and is built for the long haul. It is small but not too small and is easy to maneuver. The ceramic heating element is gentle for the hair and provides smooth, even heating.

The LCD display is great as is the fact that seven different operating temperatures are available. This allows the brush to work well with all hair types and textures.

The InStyler heats up faster than any other hair straightener that I have encountered.

It is fully heated and ready to use in 30 seconds! It is very good time for professional use.

Last but certainly not least, I need to mention the essential safety features. This unit features an automatic shut off. This, in my opinion, should be a mandatory feature on all hair straighteners. If you forget to turn it off or unplug it, the brush will power down in just a few minutes.

The Cons

The only thing that comes in the box is the brush itself. There are no instructions included. There is no carrying case either. A carrying case is always a welcome addition as it provides for easier storage when traveling and eliminates having a cord wrapped around other items in the suitcase.

The only other negative, albeit a minor one, is the fact that this brush does not have a hanging hook. This is compensated for by the fact that the body of the unit is cool to the touch. So, with that said, it can be laid down on its back after the completion of each use.

All in all, this is an excellent value for money. It is fast and easy to use. It is designed well and looks nice.

  1. Does the back side get very hot? With my previous straightening brush, I had to deal with the back side always being way too hot for me to handle; so eventually, I gave up on it.

    1. Not at all, that’s what I love about it! I can assure you it’s a warm temperature and that’s it! The bristles do get very hot though so please be careful about that.
