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.
Most of the hair straighteners we reviewed heat up in under a minute, but the Cloud Nine Original Flat Iron has to be one of the fastest on the market! In as little as 20 seconds, this hair straightener transforms from cool to hot, hot, hot! With this model, there is no need to wait around for your hair straightener to warm up, which means you spend less time getting ready in the morning and more time getting on with your day.
One of the Babyliss’ major drawbacks, and why we only recommend this flat iron for experienced users, is the outside gets hotter than any of our other picks. Hot to the point that it was too hot to hold. One tester said she was “afraid to accidentally touch the top of it.” Others said they could feel the heat against their scalps. At first, another tester said she didn’t mind the heat. This was moments before she burned the top of her hand when it merely grazed the side of the tool.
Nor does it speak to those of us who work long hours at our job - who support our families and who struggle with issues like how to pay the bills or how to put the kids through college - who have limited time and energy for training - and who are more interested in how to train for lifelong strength and health than in how to gain 30 pounds of muscle in six weeks.
The last time I used a legitimate curling iron, I was getting ready for my eighth grade Halloween dance. This is not an exaggeration. I’ve been using a flat iron to curl my hair since the very day I learned how. One of my closest beauty-savvy friends showed me the basics, I begged my mom for a great straightener that curls hair, and I perfected the skill by watching flat iron curling tutorials on YouTube. Yeah, there’s a slight learning curve, but once you know how to use a straightener to get curls, you’ll never go back to curling irons again. No clips, no burns, no need for gloves, and one tool covers all your bases.
“I bought the HSI titanium tourmaline ionic flat iron and I was so impressed with it. It glides so smoothly down the hair without any tugs! The digital display screen lets me adjust the temperature without any problems, it heats up fast, and I love that it comes with a pretty purple pouch, glove, and argan-oil serum. I also own the digital HSI ceramic ionic flat iron from 2013, and it’s still going strong, but I do like the titanium iron better, and I see myself using for it for years to come. It leaves my hair shiny and soft!”
Titanium is a lightweight metal that heats up very quickly and can hold high heat at a consistent temperature. This material is ideal for those who have thick, curly, or natural hair that can be more difficult to straighten. Since it's lighter than ceramic, it also makes for a lighter hair straightener overall, which means less arm strain as you're taming your mane. As someone who has very thick hair, I can attest — Any feature that can make styling easier and faster is a plus.
This feature is particularly helpful if you have textured hair with waves or curls, which can become damaged so easily by heated styling tools. That said, it is not clear which heat setting is ideal for users with thick or somewhat straight hair. This may make this slightly more difficult if you are using a flat iron for curling purposes or if you need to straighten an especially thick head of hair each day! However, we are confident that a little tinkering is all it takes to find the perfect heat setting for these different hair types and styles, so you can rest assured that this hair straightener can still meet all your hair styling needs!
Ask any seasoned hair stylist for a flat iron recommendation, and you will hear the same brand time and time again: CHI. Known the world over as a leader in hair care and styling, CHI is your go-to name for salon results at home. While CHI offers a variety of designs (and fun colors!) to choose from, the brand’s G2 Ceramic and Titanium model is what caught our eye when researching the best hair straightener. This hair straightener is packed with high-tech features and an upgraded, ergonomic design for the shiniest and straightest do’ you’ve ever seen!
With well over 25,000 reviews, the HSI Professional Ceramic Tourmaline Ionic Flat Iron is one of the best straightening irons you can get, but because of its thin build and rounded plates, you can also use it to curl your hair. It’s got solid ceramic plates to reduce damage, evenly heat hair, and promote shine, and if you’re a traveler, it’s got a dual voltage that can be used anywhere in the world.

The titanium plates in the BaByliss Pro Nano Titanium Straightening Iron were designed to conduct high levels of heat (again, up to 450° F!) in a short amount of time. Coupled with the Nanotechnology that is packed in each plate, this hair straightener is ideal for anyone that experiences unwanted frizz or static on a regular basis! The titanium also acts as a barrier from corrosion keeping your hair straightener and precious strands free of build-up for years to come!
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:
You wage an endless battle against frizz so your hair straightener is one of the most important tools in your bathroom. When it is time to upgrade to a more professional model or replace an old straightener that has seen better days, check out eBay. Easy search functions make it simple for you to find a ceramic hair straightener that fits your style and your budget. Many people prefer ceramic, titanium, or tourmaline plates, and some straighteners come with interchangeable plates in different materials or designs to create crimped or wavy looks. Pick up a mini hair straightener that is perfect for traveling, and you always look good no matter where you go. Many reliable sellers on eBay offer a vast inventory of straighteners in different colors, styles, and types. All you have to do is find the hair straightener that suits you and maybe pick up a spare, just in case.
Celebrity hair stylist Priscilla Valles’s go-to straightner is the classic GHD 1-inch straightener. “I start in the nape and bring down small sections, one row at a time and I use a GHD flat Iron with a comb in the other hand,” says Valles. “I place the comb in front of the iron while ironing at the same time in a slow motion all the way down. Never stopping cause that will cause dents in the hair. At the end a dime size of ouai rose from top to bottom just to add some shine and control any fly aways!”
The BaByliss Pro Nano Titanium Straightening Iron really is the Baskin Robins of hair straighteners, making it the perfect choice for anyone that wants to straighten their hair quickly. Whether you have naturally short hair and opt for extensions on occasion or you just chopped off your do’ into a new pixie cut, you will have a hard time not finding the perfect heat setting for your hair so many choices!
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 solution? Automatic shut off. That way, even if you do forget to turn off your hair straightener, you can be at ease knowing it will turn off on its own automatically.

Still, a little peace of mind and extra precaution never hurt.
