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.
This lesser-known brand made a great impression when it was available on Amazon (you can now buy it at TerresaBeauty.com), where the majority of reviewers gave it five stars. "It allows my hair to glide so smoothly through the plates, never snagging it," says one shopper. "I can straighten or curl with this straightener and it works great," says another.

“I wanted a straightener I could use on wet hair, since I’m usually on the go and don’t always have time to dry it. With this Wet 2 Straight Hair straightener, I was able to straighten my hair after it was towel-dried and only had to go over my hair twice for it to be completely dry. Granted, I have semi-thin hair, so it doesn’t take too much to straighten it, but with other straighteners, I would have to go over it about three or four times and couldn’t straighten it when it was wet.”
The ability to create bouncy curls or waves with a flat iron (we know, it seems counter-intuitive!) is a biggie in the beauty industry and merits a bit more discussion. If you’re totally lost and there aren’t enough video tutorials on the planet to explain this weird yet awesome process, don’t worry! Just follow along with our step-by-step guide and you will be curling with the best of them in no time!
This mini straightener is perfect for my bangs. I also used it to make some longer strands wavy by pulling it down at an angle. I bought it for travel abroad in Denmark since it has the dual voltage, but have only used it in the US so far. It heats up fast and makes my hair super smooth. And the free sample of conditioner smells soooo good and made my hair super soft!
Thankfully, we’ve learned a lot about hair care and preserving your hair’s natural integrity while styling. However, this wasn’t always the case. If you ever had a perm done in the 80’s or teased your hair to holy heaven in the 90’s, chances are pretty good that your hair has endured a bit of damage. The same can be said if you color your hair on a regular basis or recently went from your natural brunette color to a bright platinum blonde. No matter how the damage was caused, there are certain features you will want to shop for when selecting the ideal hair straightener for your course hair type:
When you feel like it’s time for straight, shiny locks, we’ve got your back. Our flat irons are so well-designed and powerful they can straighten even the curliest of hair. Our selection of hair straighteners also come in a variety of sizes, colors and shapes, and some even include thermal bags or travel containers so the flat iron is protected. Many of our irons also include a warranty to guarantee that the electronic components are functional for years to come. Depending on how long or short your hair is, or the type of styles you seek, you will need to select a style that best suits your styling needs. For instance, a 1.5-inch iron works best on medium to long hair, while 1-inch irons are typically made for shorter hair.

Be sure to protect your hair against heat damage with Xtava’s Heat Protectant Spray every time you style. Not only does our heat protectant coat your hair with a lightweight layer of protection, but it also repairs hair from the inside-out with broccoli seed and Brazilian pequi oils to replenish moisture, restore shine, and infuse essential nutrients.
Size matters. With plates too big or too small, you’ll have to make multiple passes. This exposes your hair to high heat longer and increases the risk that you’ll do damage. According to Janine Jarman, owner and operator of acclaimed Hollywood salon Hairroin, a 1-inch-wide plate will do for most people, and if you want to use your iron for anything other than straightening, like creating curls or waves, you’ll need a 1-inch plate; anything larger won’t make the waves or curls tight enough. She also pointed out length is important too. “You need plates to be at least 3 inches long, or close to it, so you’re not spending a ton of time with small sections.”
The Chi Air is similar to other Chi tools and has that iconic sleek design with gold plates. However, one feature our testers believe makes the Chi Air stand out against the Chi Elite and others is that it’s so lightweight. True to its name, the tool is lighter than other flat irons which makes it easier to manage when styling. One tester believed the light design even made it snag less when passing over hair.
Let’s face it: styling your hair is a 360° job. That’s why the folks at Cloud Nine have designed their Original Flat Iron with a swivelling 360° cord! No more tangled messes or twisted cords, with this hair straightener you can easily reach delicate fly-aways and seemingly invisible back sections without the hassle of a tangled or knotted cord ever again. When it comes to hair straighteners, the Cloud Nine Original Flat Iron really proves that perfection is in the details!
It is packed with the most advanced technology to give you shinier, smoother results that lasts longer. The one-inch wide heating plates are made of high quality, durable ceramic that provides an ultra smooth surface so that you’re hair glides through. The ceramic plates are then coated with tourmaline gemstones that emit negative ions to give you a frizz-free shine.
It becomes extremely hot – up to 392 degrees Fahrenheit, and it holds that heat until you shut it off. Because of this, you can straighten any type of hair with Chi, including very thick and coarse tresses. So if you have such hair, this iron could be your best option. It is not only designed to straighten but also to curl hair. Thanks to its ergonomic design, you won’t strain the hands and wrists during use.

“I’m in ‘ahhh’ at how awesome of a straightener this is. If you ask me, it’s a lot better than the high-end brands. It leaves my hair silky-smooth and shiny. I absolutely love its features, and you can watch the heat meter rise as it’s heating up. To me, five stars is not enough to rate this product. It’s definitely worth the money. I’m in love with this straightener. Also, the lock on it I found to be a awesome bonus.”
