HSI Professional Flat Iron

Jan 14, 2022 @ 4:41 pm By Elley

Get beautiful hair by using HSI professional flat ironWhy is this model a best seller? I set up this site because, as a stylist and flat iron fanatic, people are often asking me for flat iron recommendations and I want to share my knowledge and point people in the right direction for which hair straightener to buy for their hair type, style and price range.

As I’ve worked my way through the brands, I’ve found that some companies use the word “professional” to sell products that aren’t really of a professional standard. When you buy hair straighteners for under $50, you can’t really expect a salon finish. My rule of thumb is that the models which are actually “professional” are generally priced at $80 and above (some well above!) until now.

A Professional Iron with a Tiny Price tag?

The HSI professional 1 ceramic tourmaline ionic has really got me scratching my (perfectly straight and shiny!) head. It seems to have all the features of a professional iron, customers are totally raving about it and it even comes with free stuff! But you can buy it for under $50. What?

HSI Professional Ceramic Tourmaline Ionic Flat IronIn this hsi ceramic flat iron review, I’ll take a look at the specs, features and reviews of this model to try and answer the three burning questions I have about it:

  • Is it really a “professional flat iron” or is HSI using the term too loosely?
  • What is it that people love so much about it – how has it risen to the very top of Amazon’s ratings.
  • Is it really as good as they say and, if so, why is it less than HALF the price of the professional hair straightener best brands?

BUY HSI PROFESSIONAL FLAT IRON-AMAZON-

Free Stuff!!!

At the moment, there’s a really great hair straightener deal on Amazon.com. When you buy the HSI professional, you receive a free Argan oil conditioning treatment and a heat protective glove. This is great because hair straightening with straighteners can get pretty hot and this package means that your hair and your hand is protected! If you’re worried about damage from flat irons, then including the Argan Oil treatment in your hair straightening methods is very advisable because it keeps your hair in optimum condition, strengthening the cortex, cuticle and shaft against damage. Check out my heat precautions article for more info on this.

Everybody loves a free gift and this package, combined with the highly rated HSI flat iron, makes for some of the  best value hair straighteners I’ve ever seen!

Top Seller on Amazon.com

The HSI Professional is currently the Number One Top Seller on Amazon.com. And it’s held this throne for an impressive amount of time: they were the top hair straighteners 2014, 2015,2016 and look set to hold onto the title in 2017, too!

There are well over 23 thousand Hsi 1 ceramic tourmaline ionic flat iron hair straightener reviews!!! And it maintains an average consumer rating of 4.5 stars with more than 70% of users giving it the full 5 stars. This really is staggering because most models I’ve looked at might have a few hundred reviews but this one has 23,000. That’s a whole lot of buyers. I also think that people are more likely to write a review if they’ve got something to complain about than if they love it and yet, after so many thousands of Hsi flat iron reviews, its rating hasn’t dropped. People LOVE this flat iron brand!

Maybe you need to see the reviews for yourself. Can this many satisfied customers be wrong?

BUY HSI PROFESSIONAL FLAT IRON-AMAZON-

Take it Anywhere

One problem that lots of models, even those from the top professional hair straighteners brands, have is that they can’t be used outside the U.S.A. Our voltage is 120V (60Hz) and lots of models are made only for that voltage and will short out as soon as you put them in a foreign socket. That’s no good for the jetsetter!

The HSI tourmaline ceramic hair straighteners is world wide dual voltage compatible 110 to 220 volts. All you’ll need is a socket adaptor and you can slip it into the handy little travel bag and take it anywhere you like!

Promising Performance

So the price is right and the reviews are promising but what about the performance? The hsi professional 1 ceramic tourmaline ionic flat iron has a number of excellent features. Ceramic tourmaline plates allow you to straighten at lower temperatures, reducing the risk of damage. They are also excellent conductors of the negative ions that fight frizz-causing static. Easily adjustable temperature settings mean you’re in control of how much heat you put in your hair and infrared heat technology enhances the style result. Apart from floating plates (which do make straightening faster and reduce the chance of painful snagging) these flat irons have all the features of far more expensive professional models.

Versatile Style

Lots of people ask me which flat iron is best for curling, flipping or waving hair as well as straightening. I always recommend that they look for an iron with 1 inch plates and a rounded, narrow housing. This is because you’ll be able to catch the hair in the hair straightening tongs and flip it around for a curl without making an “iron line” or “halo” like you get if the casing is too thick. The HSI has 1 inch plates and a nice, narrow housing so it meets my curling criteria perfectly.

My Verdict: The Best Cheap Flat Iron

You might have noticed that I’m actually really excited about this iron!

I’m a total flat iron snob and I’ve spent A LOT of money on them in my life. Usually only the professional hair straightener best brands get a full 5 star rating from me so it feels a bit strange to give my highest recommendation to a $50 straightener. But I just can’t find fault with this model: even when I compare hair straighteners with much more expensive brands. So, I just have to give it the full 5 stars – it’s the best and cheap hair straightener.

Actually, the only thing “cheap” about it appears to be the price tag!

I hope my Hsi hair straightener review has helped answer some of your questions. I definitely feel like it’s all a bit clearer in my head!

If you think these might be your next hair straighteners, pop over to Amazon quick to see if the deal’s still on. They do tend to sell out pretty quick because they’re so popular and can be hard to get hold of!
