Best HSI Flat Iron Reviews (Recommended Picks)

1. HSI Professional Ionic Flat Iron

Curly, straight, curly straight. We can never seem to decide which look we like better. With the HSI Professional 1 ¼” Ceramic Tourmaline flat iron, why should you have to choose? You can have the best of both worlds in one salon-quality flat iron.

Though this hair straightener is on the pricier side of flat irons, it is easy to see why it’s worth the extra money.

The even heat of the ceramic and tourmaline combined with advanced infrared comes in a flash, practically right after you plug it in.

Pros & Cons:

  • Sometimes that extra quarter inch makes all the difference. With the majority of flat irons clocking in at one inch, this one gives you that extra bit of wiggle room making it a better option for girls with longer or thicker hair. Simply put, you can get more styled at once.
Have thinner but medium length hair and don’t want to lose it all to excessive heat styling? I recommend you try this HSI flat iron on a lower setting and make good use of that argan oil.

Have hair that turns into a big ball the second a single percentage of humidity hits the summer air? Same idea. Try out this argan oil, but then use the HSI on a higher setting and see if you don’t notice a difference immediately!

2. HSI Professional Flat Iron

If you want the absolute sleekest, straightest style like you just stepped off the runways of Milan, Paris, or New York, you must try this ionic hair straightener. The plates are 100% truly solid ceramic (the best kind) infused with tourmaline crystals.

The advanced infrared heat is only enhanced by the tourmaline and helps shine emerge without the frizz by neutralizing the positive ions of previously damaged hair.

It, therefore, prevents further damage from happening too. Your mane is left uber hydrated but with the perfectly straight and smart look, you so desire.

Does your hair seem damaged no matter what you do? Does it just seem stubborn beyond all help? If so, then I recommend you try this HSI ceramic tourmaline iron.

3. HSI Flat Iron

High heat can be daunting to any first-timers, so this will protect both your hands and your countertops. The one-inch plates are perfect for any hair length but can also reach closer to the root, including bangs.

The beveled edges allow you to sweep or feather them out all the way to the end, never leaving you with that awful “flat fringe” look.

Advantages of HSI Professional Flat Irons

    The flat irons have most of their dials in between the plates. We all know it’s been one too many times that you have touched the digital dials or knobs by mistake. Nothing is as annoying as realizing you’ve switched off the flat iron mid straightening. Whats worse would be changing the heat settings because a fine haired person will end up burning their ends or locks.

  • The swivel cord:
    The best thing about almost all HSI professional products is how they have a swivel cord; you can say goodbye to those awkward turns and twists you make around your head trying to create a certain style.The swivel cord allows you to style at angles. Their cords are also very long so you can bet that moving around your bathroom or using the tool in another room won’t have to be a hustle.
  • Long-term warranties:
    Hsi is one of the companies that are very generous with its warranties. There is a certain reassurance in having a product with a long-term warranty.You will feel safe in buying your flat iron or curling rod if you have a larger warranty. It also shows a lot of confidence on the side of the company in their product. The company is also quick to return or replace any defected items without fail.
  • Great customer care services:
    Now here comes a company that knows the customer comes first. The HSI professional company knows how to treat its customers and how important it is that they cater to all their needs so if it’s a returned item or information on a new one his customer care has you covered. The investment this company has made on its human resource and it departments in term of customer care means you get fast and reliable answers to all your queries. One customer on Amazon was quoted saying “I bought one of their flat irons the handle was faulty after a month, and I sent it back four days later I got a new one in the mail. I love this company fast service, and they don’t take you around in circles as long as you have a genuine warranty for your product”.
  • The not so good:
    Have you ever noticed how a few of a company’s items just don’t seem to belong? Some of the older versions of flat irons from HSI are great, and everything but has 6 and 7-foot cords. If you’re a home user, this isn’t a problem, but if you need to use the tools for professional use, then it’s obvious this will be an issue. When moving around in a salon, you need a long chord that can allow you move around both the counters and the styling chair easily.
  • A few flimsy handles: Some of the lower end flat irons can at times feel flimsy. The plastic used is loose and squeaky for some of the items. Not all of their low-end products are weak though just a few. We think it might be due to a large number of features. They may have cut down on the material covering the plates, but the plates themselves are just great.
  • If the plates are of high quality, then it’s only fair to give the flat iron a chance. It’s the plates we should be interested in. You really can’t find much fault with HSI professional flat irons they are made almost to perfection. The great thing about the flat irons is that they are versatile and cater to all hair types. If you have long or thick, coarse hair then a larger plate will do you good. Shorter or finer hair will require a smaller plate, and you can find the different types of plates on their website. There is something for everyone whether it’s the fine haired or the long-haired that require a longer plate size you better believe that HSI will provide it all.The main reason this company has kept its success all these years is because of its durability and consistency.So you can trust that HSI professional will provide amazing services. Several blogs and reviews online will prove this to you.
