The question is, does it live up to all the hype? There are more than 30,000 reviews on Amazon, 70% of these reviews give a 5-star rating, and 14% give a 4-star rating. According to the numbers, the HSI Professional truly is a high-quality product that is well-deserving of the attention it's been given. Buyers love how quickly the HSI Professional heats up, what it does for their hair, and how easy it is to use— even on short hair.
As an added bonus, titanium has also been found to resist rust, so your hair straightener will keep its out-of-the-box look for years to come. This is particularly important when you are making a long-term investment by purchasing a high-end or professional hair straightener. After all, you wouldn’t want your car or bathtub to start rusting after just a couple of uses and the beauty tools you use for your flowing hair should be no different!
The HSI 1st Gen Professional Ceramic Flat Iron is designed with tourmaline-infused ceramic plates, generating negative ions and allowing smaller water molecules to penetrate into the hair shaft to reduce frizz and static. Built for durability and lasting results, the floating plates give the flexibility to flip, curl or straighten your hair – all with a single iron.
Derek Yuen, the man responsible for Cole Sprouse's grown-up new look, recommends the GHD Platinum Professional Performance iron. The flat iron is consistently and evenly heated at 365 degrees, which is safer and less damaging on the strands. “The beveled edges also allow for infinite styling possibilities, not just just for straightening hair,” says Yeun.

T3’s white and rose gold flat iron seems too pretty to reliably function, but hey, sometimes miracles happen. There are four temperature settings ranging from 260 to 410 degrees, and the tool heats up in about a minute. Its ceramic plates are infused with tourmaline, a mineral said to make hair extra smooth because it emits negatively-charged ions. There’s no scientific evidence to support this, but my unscientific bathroom study found that this flat iron does indeed make my hair look shinier.
A lot of people don’t know there are tons of ways you can style your hair with a flat iron, and this actually might help you decide what size iron to get. You can curl, wave, straighten, add body, twist and more – just with a flat iron! Your straightener is so versatile you can skip most other styling tools and save money by investing in one that will do all of this for you. I walk you through different options for styling with your flat iron so you get the hairdo you want.
Xtava’s two inch-wide plates are massive, making them perfect for people with thick or coarse hair. Aside from the plates, everything else about this flat iron is fairly standard. You can use it at a temperature range in between 265 and 445 degrees Fahrenheit, the plates are made with tourmaline and ceramic, and it takes less than two minutes for the tool to fully heat.

It is important to consider what options are important to you when selecting a hair straightener. You must select a hair iron with a heat setting that fits your needs. If you have fine hair, a lower heat setting may be sufficient. However, thick coarse hair may require a higher heat setting to achieve your desired look. Plate size should also be considered. A flat iron with small plates might be best for shorter hair, while a flat iron with larger plates might be best for longer hair. Some hair straighteners have features such as temperature readouts and rollers that might be important to your needs.
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:
“Infrared is so beneficial being that the wavelengths are longer and can penetrate deeper into the cuticle heating the hair from the inside out, keeping your hair's own natural moisture, leaving the hair smooth (and) shiny and keeping it extremely healthy, versus other conventional styling tools that actually pull moisture out of the hair, leaving the hair dry, brittle, dull and damaged,” said hair expert and stylist Gina Rivera.
According to Jarman, you should never have to use both hands to clamp the iron down on your hair. You not only risk burning your fingers on the plate end, but this can pull at your hair and break it. High-quality, modern irons are designed to clamp together from the handle end only, so if you find that your iron requires pressure on both ends, it’s time to upgrade.

If you are interested in adding the benefits of keratin use into other aspects of your hair care routine, treat yourself to a keratin-rich hair mask once per week! There are dozens of fantastic keratin masks on the market to choose from (and even in your local drugstore!), but we love Naat’s Brazilian Keratin Intensive Hair Mask (which you can buy here from Amazon) for a consistent shine every time!
This styling iron has 1-inch plates, allowing it to do more than just straighten. It can also curl, flip, and be used to add volume if your hair tends to fall flat. It heats up in under 30 seconds so you can start styling almost right away, and there are a wide range of temperature settings from 250 degrees to 460 degrees Fahrenheit. While the high-temperature options make this straightener ideal for other hair types, too, if you do have fine hair you'll want to keep this in the lower temperature range.
The curling iron can also have either a spring-loaded, Marcel, or clipless handle. Spring-loaded handles are the most popular and use a spring to work the barrel's clamp. When using a Marcel handle, one applies his or her own pressure to the clamp. Clipless wands have no clamp, and the user simply wraps hair around a rod. Most clipless curling irons come with a Kevlar glove to avoid burns.
I've used this product once as soon as I purchased it. I read really good reviews about it and since I already own an xtava blowdrier, which I LOVE, I decided to give this flat iron a shot. It is amazing. It heats up very quickly and Its really good for thick natural hair, which is the kind of hair I have. I first washed my hair and the blow dried it with the xtava blow drier using a comb attachment on it, and then I used the flat iron. I've uploaded pictures from the before, during, and the after product. I recommend it for natural
The Lanxim ceramic tourmaline argan oil flat iron is a great option for this type of style because it’s got one inch plates that have advanced infrared heat technology, an adjustable temperature that lets you personalize the heat levels to your hair, and a swivel cord that won’t get tangled. The floating plates are also infused with argan oil to keep your curls soft and healthy.
Flat irons can get pricey, but they’re an investment. The Chi Elite is inexpensive when compared to other high-end tools in the industry, making it a safe bet for those new to hair styling. Though it may be more expensive than some hair straighteners, it offers a high level of quality that the others don’t (not to mention it’s a Chi, which is known for quality). We tested the HSI, which is about $60 less expensive than the Chi Elite, and its cheapness was apparent at first glance. It did nothing for any of our testers’ hair. If you’re a beginner, the Chi Elite is a great first flat iron.
Eight embedded sensors regulate and evenly distribute the heat on this ceramic iron, minimizing damage and increasing shine and smoothness. With adjustable temperature settings that go as low as 140 degrees (the coolest we've ever seen), it's ideal for anyone with super fine hair, or to smooth out the tiny frizzies around your hairline. It also comes with a lifetime warranty, which is never a bad thing.
