We started with six flat irons but ultimately dropped two because they didn’t work well on any of our testers’ hair. The inexpensive, but highly rated HSI Professional Glider Ceramic Tourmaline Ionic Flat Iron was bulky and awkward. Testers said it felt like two pieces of plastic passing through their hair. We thought the NuMe Megastar Hair Straightener, a popular and more high-end tool, would be a clear contender for our list. However, testers said it snagged hard against their hair to the point of hurting. It was also difficult to hold closed when styling. Because both of these flat irons received such low ratings among our testers, we didn’t include them in our top picks.
In the end you want to make sure that your hair is protected no matter what hair straightening treatment or tools you choose. Many hair straighteners are for daily discipline and upkeep. There are lotions, sprays, balms, serums and cremes to help you tame wavy or curly hair, control frizz or protect from humidity. Several hair straightener creams offer protection against damage from hair dryers and hot irons. Look for the hair products that will protect your hair and keep it smooth, shiny and silky.
Whether you have particularly curly hair or thick locks, this T3 hair straightener is designed to leave you with a shiny finish in a fraction of the time of other hair straighteners on the market today. Specifically, the T3’s smart SinglePass technology maintains consistent heat throughout the entire plate to straighten all hair types with one glide.

I've owned a Chi flat iron and I love this one much better! It heats up in 10 seconds and I like the dial that lights up on the side with the LED lights . You can see temperature settings easily because it's lighted. The ceramic plates on this iron definitely makes this a "one" pass straightener. It also is cylindrical so it curls your hair as well. I have very thick hair so I use the full 450 degrees.


The two strips of silicone atop Bio Ionic’s flat iron plates seem silly, but they serve an important purpose. By buffering the outer edge of the plates, they reduce your chances of hair snags. They also force you to glide the flat iron more slowly through your hair (they are called speed strips, after all). While the slower technique maximizes shininess and smoothness, the speed strips can become a bit of an obstacle if your hair is thick.
I've owned a Conair, Chi, and I-Tech straighter before, but this one is FABULOUS! A lot of research was done before I made the decision to purchase this one, and I feel like it paid off; my previous straightener was 4 years old, so it was about time. I received this new one today before I got home for my lunch break, so I had to go ahead and bust it in ;) There really is no tugging at all on your hair - so smooth, and I was shocked that it truly heats up in 15 seconds, as advertised! It also does something magical to my hair, like it adds more shine like no flat iron has done before. Mind you, my hair is very difficult to deal with. I am a Caucasian, but my hair has always been coarse, wavy, dry and thick! This iron worked beautifully on my hair. 10/10 would recommend! If it doesn't work the same after a few months, I'll be sure to update my review. As of today, I'm very happy! :)
There is a slide at the base which holds the device from opening all the way (easier for storing) but if you slide the piece it allows the flat iron to open all the way. The instructions inside the box don't explain this part, so at first I thought it didn't open very far, but once I figured this out, it became a breeze to use. Speaking of the instructions, they are listed in English, Spanish, French, and German. (I think... I don't speak/read all of those languages, but I believe that's correct.)

If you’re a hair straightening novice, you may be a little intimidated during the first few times you use your new flat iron. These feelings are totally normal (after all, you are putting 300+ degrees of heat right near your scalp!), but there is no need to worry. All you have to do is follow these simple steps and you will have the gorgeous, flowing hair you’ve always dreamt of in no time!

Cleaning your flat iron is critical to ensuring it works as well as it did the first time you used it. Over time, hair product can build up on the plates. This buildup can lead to inconsistent styling results and major snagging. To clean your flat iron, simply wait for it to cool down and wipe the plates with a cotton swab or soft cloth coated in rubbing alcohol.
These ultra-smooth plates are great for straightening stubborn strands like curls and waves and are also ideal for creating natural, finished curls (similar to a curling iron) and even beachy waves. By gliding effortlessly across hairs of all types, without pulling or breakage, the ISA Professional Titanium Flat Iron has the potential to leave your hair looking and feeling healthier after each use.
The more temperature control options you have, the more control you'll have over the heat you'll be applying to your hair. Keep in mind, any type of heat styling can be damaging to your strands, so you want to take care not to use too much high heat, especially if you're styling daily. Flat irons that have lower temperature options that start around 250 degrees Fahrenheit are ideal for those with thin, damage-prone hair. If you do have thick hair, higher heat settings can help straighten those curls. To help prevent damage, you should start with lower heat first, and then only increase as needed. Keep in mind, anything above 400 degrees has the potential to damage your hair. Even those with coarse, curly hair should stay within the 350-400 degree range to be safe.
In short YES! You absolutely can use too much heat on your hair. Burning hair is not a good smell, it’s not a good look either! You may end up having to get a pretty severe haircut if you’re not careful about the amount of heat you put directly on your locks. Read through this to get an idea of what’s safe and what will leave you wishing for a good trim (or possibly a wig).
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.
Straightening irons, straighteners, or flat irons work by breaking down the positive hydrogen bonds found in the hair's cortex, which cause hair to open, bend and become curly. Once the bonds are broken, hair is prevented from holding its original, natural form, though the hydrogen bonds can re-form if exposed to moisture.[2] Straightening irons use mainly ceramic material for their plates. Low-end straighteners use a single layer of ceramic coating on the plates, whereas high-end straighteners use multiple layers or even 100% ceramic material. Some straightening irons are fitted with an automatic shut off feature to prevent fire accidents.
Bio Ionic 10X Pro Styling Iron 1" - Nano Ionic - with Vibrating Plates The Bio Ionic 10X Pro Styling Iron 1 Inch is part of the Luxe Pro Styling Collection. Natural Volcanic Rock Minerals infused into the Bio Ionic Luxe Pro Styling Collection are uniquely refined to emit negative ions that drive tiny water molecules deep into the hair. Hair becomes hydrated and conditioned on the inside, while the outer cuticle layer lies flat and smooth, trapping moisture, giving it a vibrant shine.
No two heads of hair are the same, so the straightener that does wonders on your best friend's fine tresses may be useless on your curly mane. Luckily, there are many different types of hair straighteners. Some provide higher heat settings and wide plates to tackle thick curly hair, and others have ceramic plates and options for low heat settings that are better suited to easily damaged fine hair.

Aside from ionic and infrared technologies the Bio Ionic Onepass Straightening Iron has something that is entirely new to me: silicon covered plates. They get the hair more in order when you’re straightening, save you a lot of time and reduce the amount of heat that you need. This one is great for African American hair, but I already selected the xtava Pro Satin for that because it’s more affordable.
