HSI Hair Flat Iron Customer Review

Last update: Aug 17, 2017 14:07, April Williams

They say a woman’s glory is in her hair. Having gorgeous hair comes along with responsibilities to achieve the perfect look whether straight, curly or wavy. Today I am reviewing a flat iron for naturally curly hair that not only straightened my hair but got it done it quickly and made it look silky smooth. This product is the HSI professional ceramic tourmaline ionic hair straightener. It’s such a powerful device that it has been recognized to be the best flat iron for African American hair. To choose the best professional flat iron isn’t easy as there are many that are suitable for all hair types with brilliant favorable features that make styling effective and comfortable but this is definitely the best among its price range. So, for an affordable professional flat iron, this is an option that will not disappoint.

Basic Properties:

  • 360-degree swivel cord
  • 1-inch plate width
  • May come in red or white packaging
  • Dual-voltage (110-220V)
  • Temperature from 240F to 400F
  • Includes Argan Oil

First Impression

My first glance of this straightener, I saw a simple, portable and standard size model that came in a neat package. The packaging may differ in color of either red or white. Mine came in red.

It was about 31 cm in length. It features an on/off switch, an adjustable temperature light.

The heating plates are an inch wide and are made of high quality long lasting ceramic which provide the ultimate smooth surface for your hair to glide through easily. The ceramic tourmaline gives the hair a really lovely shine. You will undeniably have a silky smooth texture throughout. The ceramic plates heat the hair from the inside and lock the moisture into the outer part of the hair. The sizes of the plates are suitable for all types and lengths of hair, even narrow enough for fringes.


The heat can be indicated with the LED light. When it is switched on you will notice a red light which turns green when it is heated letting you know that it is ready for use. You don’t have to be the slightest bit worried about overheating or getting your hair burnt because this model has heat balance microprocessors. They continuously monitor the temperature of the plates and automatically adjust the temperature for an even distribution of heat.

The few hair straighteners I have used over the years usually just had an on/off switch with no particular settings. With this one, I can adjust the temperature to suit my hair type, which means the temperature can be easily increased or decreased to your needs.

It also has a swivel power cord that easily twists without tangling.

Further Inspection

The temperature ranges from 140º — 450 ºF suitable for all hair types. Quite often you have to deal with a straightener with a fixed temperature but it’s not the case with the HSI. Ions are emitted by the tourmaline stones which makes the hair shine. It also has a dual voltage of 110v — 220v making it suitable to use anywhere even overseas.


The HSI Professional is a definite favorite of mine as it has always given me the results I needed every time it was used.

Here are some points as to why I have found this flat iron to be simply the best:

  • First and foremost it is very affordable.
  • It is very portable and comes with a small bag for traveling.
  • The plates are made up of materials which ensure a smooth and shiny finish, exactly what everyone wants when straightening their hair.
  • The ceramic coating creates a smooth surface that allows the hair to glide through easily.
  • The sizes of the plates are suitable for all different types and lengths of hair, also being narrow enough for bangs.
  • It doesn’t take long to heat up and LED light conveniently changes a color of giving a clear indication as soon as it’s ready to use.
  • It has an adjustable temperature to suit any hair type, so there’s no risk overheating or burning hair.
  • It has a compatible dual voltage.
  • A swivel cord that does not twist.
  • After use, it cools down quickly.
  • A heat protection glove.
  • The heat resistant case. The plastic behind the heated plates does not get too hot.
  • It has the ability to either straighten or curl hair.
  • You don’t need to go over the same stands again and again.

I could go on and on but one thing I know as a certainty is the fact that I haven’t ever used a better product than this. It is lightweight, very easy to use and is available in different colors.

It actually comes with accessories that make it even more compelling. They include a small bag that comes in handy when traveling, a heat protective glove which works as a shield from the heat and an argan oil leave-in hair treatment to nourish your hair. – Talk about a complete package!

During the summer I visited a friend of mine who lives in a different city, so I got the chance to use the whole package. Of course, the pouch came in handy for the trip and when we were getting ready for a girls night, I simply applied some of the argan oil for moisture and its protective measures, put on the glove and worked the straightener through my hair and within a short time I had a perfected hairstyle. Then I styled my friend’s hair and we both had stunning hair for our night out together. The results are durable and long-lasting.

The only issue to take note of is the absence of an automatic shut off timer. So, be sure to switch it off and unplug it after every use. Also, let it cool down completely before storing it away.  If an auto-shut off is an essential feature for you then I suggest you consider the Wazor flat iron which is another top-notch styling device with all the necessary features as well as an affordable price. My sister owns this device and we have used each others and have found them both to be highly comparable.

I highly recommend this HSI professional hair straightener that will give you the possibility to have a flawless hairstyle with ease.

I wish you beautiful and healthy hair!

  1. Does the travel bag have a heat resistant interior fabric so the straightener can be put straight away after using it?

      The inside of the bag is made of fleece material. It states to let the tool cool down before storage, besides, this doesn’t take long anyway.
