Every week brands advertise that the best hair straighteners are theirs, have the most amazing features and are better for your hair than the others.
We’ve looked at 41 different hair straighteners and conducted over 67 hours of research and testing to write these hair straightener reviews I am able to recommend that the Conair Infiniti Pro Flat Iron stand out as the best hair straighteners to buy. These straightforward and easy to use straighteners have a temperature dial, which goes from 165 °F up to 455 °F in simple 10-degree segments and are very lightweight.
1. Conair Infiniti Pro Ionic Steam Flat Iron
The Conair Infiniti Pro are the best hair straighteners to buy for most people out of all the ones we tested, but we especially liked that it is around half the price of most straighteners making it great value. Being a longer straightener it also has the added advantage that it can straighten wider sections of hair at once, which can save you time (the hot plates are 5 inches long and 1 inch wide).
These are light hair straighteners, coming in at 0.52 pounds and clamping the plates together doesn’t require a lot of effort. Steam straighteners are quickly gaining popularity. The Infiniti Pro moisturizes your hair as it steams, minimizing damage and giving the hair that healthy look you want. The straighteners have a temperature dial, which goes from 165 °F up to 455 °F in 10-degree segments. On cheaper straighteners, the cord tends to be shorter, and this is no exception, with a 6-foot cord. This straightener comes with a five-year warranty – ideal if you often need to replace them.
Why our reviews are trustworthy
I have covered beauty and hair products such as the best hair dryers, the best hair rollers and the best hair clippers since we first started the site, logging weeks of research and testing in that time to find you the best products. We’ve looked at a huge number of hair straighteners and consulted with experts, like Mark Knott, Director at Toni & Guy and Yash Kamath of Princeton University to create this review.
We also keep up with reviews from other noteworthy companies that also test or review products, such as, Ipsos, Amazon, Good Housekeeping and Total Beauty though we do find that the coverage is not as comprehensive as it could be.
Then we do our own testing in-house and also have them them product tested at home. This is conducted though our own consumer product testers, who provide their feedback through our product testing panels.
Review covers the best hair straighteners before and since the last time we created this guide:
Who should get these?
Everyone wants to use hair straighteners these days, but how well straighteners will work on your hair, ie; how straight you will get it, how long it will hold for, and how much heat it will take, depends on a combination of skill, climate and ultimately your genes. The most compelling reason to buy a hair straightening iron is to straighten your hair, but you must remember that the more textured or curly your hair is, the more time and heat you’ll need to achieve the styles you want.
On the other hand though, if your hair is fine, the more likely it is that, it will be damaged with high temperatures. With practice though, you will be able to figure out the best temperature setting for your hair and how to use your hair straighteners to create the styles you want, just remember to take things slow and low when you first use them.
“We can’t say that you’ll never experience heat damage again, but by using quality hair straighteners correctly, you can reduce any heat damage to your hair.”
It’s a balancing act to keep the style you want and to keep your hair healthy, so if your current straightener doesn’t have good temperature settings, or takes many passes even at a high setting to get your hair straight, replacing it with a new straightener that gets hotter, so you can find that sweet heat spot for your hair to you can save time, but also save your hair from split ends or breakage.
If you already have some great hair straighteners you like, then you’re probably set and don’t need to get any new ones. Unless they are bust or if it’s hard to hold and move around or if your hair gets snagged in the straighteners or you are forced to apply more heat on those areas to fix them, in which case you should get new ones.
We can’t say that you’ll never experience heat damage again, but by using quality hair straighteners correctly, you can reduce any heat damage to your hair.
How we began the test selection process
We started by making a list of all of the best hair straighteners that we could find for sale in retailers stores and online. We listed 41 models in the original selection process for this category.
Temperature range, this is the biggest thing to look for when it comes to choosing a hair straightener. Hair straighteners are made up of two hot plates, made to be used like tongs, that you slide over sections of hair to dispel water, leaving your hair sleek, smooth and straight.
We all want to avoid hair breakage and split ends as far as possible. Let’s face it, hair straighteners get hot. There are no straighteners you can use to avoid this damage, because heat damage is inevitable when applying heat to your hair. Some hair straighteners go up to 450 °F, and that heat goes directly onto your hair and is not recommended by us.
Hair theoretically decomposes at a little over 460 °F, and when it dies, your hair breaks down, leaving only the external cuticle. That is bad, and irreversible. The maximum heat that hair can endure before getting damaged, is different for each individual and their hair type. So the ideal straightener gets hot, but never ever hotter than 460 ºF. This is why we rank temperature and more importantly, clear and usable temperature controls high up the list of requirements for this best hair straightener review.
Plate size, we aimed for straighteners with plates that were either long or shorter to see how they compared. We confirmed that a 1-inch wide plate is the best option for most people. There are wider plates available but they are bulkier and less maneuverable. Plus, they have more of a chance of warping if they are wider than 1-inch
Weight and cord length as they are with any beauty product are important to factor into this hair straighteners review.
Warranties were taken into account because we all know some things just break, so we checked to ensure they all had at least a 12 months warranty and scored them higher if it was longer.
Titanium plates vs Ceramic plates. It is said that titanium plates holds heat better than the standard ceramic plates. Our research and testing shows that straighteners with ceramic plates hold heat just as well as titanium plates. Therefore we ranked this low on our list of criteria.
Infrared heat supposedly breaks up water for faster straightening, but it does not do it any better than the heat does. Again this one ranked low.
Negative ions, thanks to tourmaline added to plates, theoretically to help kill static. However, in practice, if you condition your hair then there won’t be any static buildup, so we don’t believe the hype on this theory making a material difference. Another of low importance in the ranking.
After wading through hours of reading everything from product specifications, and scientific papers to consumer hair straightener reviews (plus a few charged debates between us), we were then able to whittle the list down to 15 hair straighteners to bring in for testing.
How we tested them
When we received the hair straighteners were going to test, We matched them to a cross section of our consumer panelists, in terms of age, lifestyle and hair type and then sent out the products and instructions for them to test at home, and also got them ready for our in-house panelists. We each took some time to get the basic stats for each straightener. So we timed how long they took to heat up, checked the temperature ranges and dial increments, then weighed them, measured the button placements on the grip and the cord length.
Then we tested the hair straighteners over a month and swapped them around so each of us got to use each hair straightener. We all noted down the time it took to straighten our hair and if we could style properly with them. We tested the straighteners in this way so that we could see how they worked on different hair texture, curly, thin, thick, long, and short, you name it.
Next up was to test the automatic shutoff features, so we left them on for extended periods of time and they worked every time (thankfully). We drop tested each of the straighteners a significant number of times by dropping them from varying highs onto solid, wooden and carpeted floors when they were both on and off.
After a month, we had finished testing all the hair straighteners. We then got the chance to look at the current prices for each one and were presently surprised to find that our favorite models were not always the most expensive ones, especially in this years review.

This small hair straightener is perfect for traveling. The size should not deceive you for lack of performance, though.

14. Xtava Goddess Flat Iron with LCD Display
Usually right up there among the top rated hair straighteners review, the xtava Goddess Flat Iron with LCD Display and Ceramic Tourmaline Plates appears to have slipped down from higher up the best hair straightening irons list this year.

This flat iron comes with a bonus of a happy color. That aside, it accommodates all hair type with its function of temperature control and only takes 30 seconds to heat, and you are ready to use it.

Why Buy Hair Straighteners?
The 21st century brought some changes in the hair fashion world. It starts from wild, straight, curly to sleek and puffy. If your hair does not have a good fall, if it’s too frizzy then it may be a wise decision to own the best hair straightener.
