- Low Tech Times
HSI is Equipped with 8 heat balance micro-sensors with the ceramic plate that helps to control regulate the temperature and evenly distributes the heat across the plates so that it requires fewer passes to get your precious hair done. Simple but fast.
- Products You Cant Refuse

- Beauty Shortcut Tips
What experts didn't like
All of the dials and buttons are also located inside the straightener, dangerously close to the plates. Not worth risking a burn.
- New York Times Wirecutter
A bit pricier than the bunch.
- HQ Review
The thin plates can take longer to style extremely thick or curly hair.
- The Consumer Guide
However, this sleek look is partly achieved by placing the temperature and power controls on the inner side, next to the hot ceramic plates. While a glove was included with the flat iron for hand protection, our testers were bothered by the control’s perilous location.
- Your Best Digs
This flat iron has a regular size (12 inches long), so taking it on holiday may not be that convenient.
- My Straightener
Controls inside the iron make it difficult to manage heat settings during use
- Heavy
Cannot be used on wet hair.
- Low Tech Times
Both of the temperature control switch and the ON/OFF are positioned in a very awkward place. It’s more towards the inside of the straightener. So when you operate with it you have to be careful so that you do not burn yourself while operating the iron or while adjusting the temperature. For safety measures it would make more sense to put it on the outer side of the machine.
- Products You Cant Refuse
It loses a significant amount of heat during straightening. The handle becomes hot as well.

From The Manufacturer

The Glider flat iron has tourmaline-infused ceramic plates that use 8 micro-sensors with HeatBalance technology to evenly distribute heat by regulating the temperature so that you spend less time applying heat to your precious hair. The iron heats up quickly, and the temperature can be adjusted between 140-450°F, giving you total control in matching the heat to your hair type. The tourmaline infusion reduces frizz by generating negative ions, and the ceramic is built for durability and lasting results. Plus, the floating plates give the flexibility to flip, curl or straighten your hair, all with a single iron. The real reason why people can't get enough of this iron is because not only is it feature-filled and battle-tested, but it comes at a great price, with a satisfaction guarantee and a 1 year warranty to match.

An Overview On Hair Straighteners

Do you rely on the best tools to get your hair just perfect every day? If so, you’ll want the best hair straightener you can get. This tool can take frizzy hair down to a stunning straight style with no time at all. With several varieties available, you will need a bit of information to find the best straightener for your needs. Let’s see what the best straighteners have to offer.

A hair straightener, or flat iron, is a product that looks like a hefty set of tongs. You “brush” your hair between the two flat handles that are preheated. Your hair then turns out silky smooth with little to no frizz. Although it seems like a simple product, flat irons have gone through many transformations to keep your hair damage-free. Straighteners are made from many different materials, each claiming to be better than the other. Some materials used in hair straighteners include titanium, silicone, ceramic, Tourmaline and Teflon. They will all effectively straighten hair, but some are better for certain hair types than others.

You will have to know your hair type to decide on the best hair straightener for you. If you have fine hair, you’ll want to choose a straightener with multiple heat settings. Fine hair can be singed by hair straighteners so it is important to use low heat. The Remington Anti-Static Flat Iron Hair Straightener and the Kipozi Professional Flat Iron With Digital Display both have digital inputs for you to set the temperature you need. If you have thick hair, you’ll need a high-heat straightener and temperature control isn’t as important. The Kipozi 2-in-1 Hair Straightener & Curling Iron is a high-heat and quick-heating flat iron perfect for thick hair. If you have curly hair, you’ll want a flat iron that features Tourmaline as it prevents the frizz that curly hair is known for. There is a straightener for every type of hair to prevent damage and give you that perfect straight, frizz-free hair.

If you are a frequent flyer, invest in a flat iron that travels well. The HSI Professional Ionic Flat Iron Hair Straightener has its own travel bag, a heat-resistant glove, and a travel pack of argan oil. Find convenience when you are on the go with this great travel flat iron.

DYWM Fun Fact

Tourmaline is a gemstone that is crushed into extremely small particles and then infused onto the hot plates of the iron. This substance allows the flat iron to straighten hair at a much lower temperature. These flat irons are becoming quite popular especially for consumers with fine hair.

The Hair Straightener Buying Guide

  • Although it isn’t necessary, using a heat-resistant glove to handle the flat iron will make you much more comfortable while straightening your hair.
  • Choose a flat iron that has anti-static characteristics to make straightening easier.
  • Try to use a protective product like argan oil to give your hair a sheen and also protect it from high heat.
  • Opt for a hair straightener with a warranty.
