Despite these downsides, the HSI Professional comes with plenty of positives, including extras not often found with other hair straighteners. Along with the straightener, you'll receive a carrying case, a heat-resistant glove for easier hair styling, a style guide, and a travel-size argan oil leave-in hair treatment serum to smooth and protect your hair. This is more than most high-end hair straighteners come with, all for a fraction of the price.
Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy (like pillows), but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ‘em) products and single out the most convincing. While we’ve written about the best curling irons, hair dryers, and even a certain curling iron used on the Victoria’s Secret Angels, here, we’re going deep on the best flat irons and hair straighteners on Amazon. (Note that reviews have been edited for length and clarity.)

Negative ions have been a longtime fan favorite in the hair care industry, and it is no surprise that this same technology would appear in our top picks for the best hair straightener. Negative ions have been found to reduce static and frizz while locking in moisture, and the same goes for your hair when you use the CHI Air Expert Classic Tourmaline Ceramic Flat Iron!
EDITOR’S CHOICE: CHI has and always will be a powerhouse brand in the hair straightener industry, and the company’s new G2 Ceramic and Titanium Flat Iron is no exception! Packed with ceramic and titanium technology, this hair straightener was designed to give you silky, shiny styles without snags. We also love its easy-to-read, color-coded temperature settings, so you know the temperatures that you are using at any given time!

A few swipes from a professional hair straightener can finish off a high ponytail, restore life to split ends, and give your natural curls a relaxed look for a night or two. No matter what your natural hair type may be, there is a hair straightener as unique as the gorgeous locks on your head! Here are just a few of our favorite hairstyles that can be achieved using a professional hair straightener like the ones we’ve reviewed here:
In addition to a fast heat-up time and multiple temperature settings, the 9-foot cord and 360 swivel make for easier styling and prevents and tangling. You can also travel with this styling iron thanks to the dual voltage settings. Anti-slip edges and floating plates allow your hair to glide effortlessly between the plates, with no pulling or snagging which can be especially damaging for fine hair.
If your hair is thick, coarse, or supercurly or you swear no tool in the world can get it straight, we challenge you to try this wacky-looking tool. Plastic bristles comb and detangle hair right before the heat hits it. Then the teamwork of a heated rotating cylinder and a ceramic plate straighten and polish even the most unruly head of hair without so much as a tug or a snag.

When it comes to hair straighteners, the Cloud Nine Original Flat Iron really proves that perfection is in the details!
Martin Penny, Gary Douglas, and Robert Powls founded ghd in 2001.[7][8] The three collaborated to buy the rights to a hair straightening iron from a South Korean inventor.[9] The brand quickly took off organically, and the company did not even begin advertising until two years after its launch.[10][11] By then, hair salons and word of mouth carried ghd to £12 million, against a forecast of between £3 million and £4 million.[9]
We’ve all heard the saying that the grass is always greener on the other side, and our hair types tend to follow the same old adage. If you were born with a head full of beautiful curls, you probably spent your childhood longing for straight hair; if you were born with bone straight hair, then you’ve probably spent more hours than you’d care to admit with a throbbing curler-induced headache. No matter how hard we may try to love the hair we’re born with; the truth is that most of us wish there were something else perched on top of our heads from time to time.

If your hair is plagued by tangles and knots on a regular basis (even in between straightening!), try switching your hairbrush out for a wide-toothed comb! The added space in between the teeth gently separately knots and tangles without the painful “Ouch!” with each stroke. If that still isn’t enough to tame your stubborn tresses, try a wet brush! These brushes are specially designed to work through knotted, wet hair without any tugging or pulling.
