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.
There are 25 heat settings (200 °f-450 °f) that are digitally controlled. It heats up to 450 degrees almost in an instant, making it a perfect solution for maintaining keratin treatments. You can use it without the infrared lights and still get great results, but when you turn them on, you will not believe the change in your hair quality, that will be visible immediately.
Coming in at a close second, the CHI G2 Ceramic and Titanium Flat Iron is our second editor’s choice as the best hair straightener on the market today – featuring fool-proof and color-coded temperatures for easy straightening or who just wants to protect their luscious locks. We also love the digital display that is featured on the CHI G2 model along with its combination ceramic and titanium design for optimal shine!
If you lived through this particular time in our world history, then you probably remember the super straight hairstyles that we all sported a time or two (bonus points if you took a photo of yourself like this in your bathroom mirror using a digital camera!). For reasons we may never know for certain, sharp and straight hair was the hairstyle of choice back in the early 2000’s giving the good old hair straightener somewhat of a bad reputation.
4. The button placement is very similar to the Remington flat iron. When the iron is powered on, quickly press the power button 2 times and a small lock icon will appear on the digital indicator under the Fahrenheit symbol. When the lock icon is visible you cannot change the temp or turn it off by accidentally pressing the buttons. To unlock, quickly press the power button 2 times again and the lock icon will disappear.
In addition to a fast heat-up time and multiple temperature settings, the 9-foot cord and 360 swivel make for easier styling and prevents and tangling. You can also travel with this styling iron thanks to the dual voltage settings. Anti-slip edges and floating plates allow your hair to glide effortlessly between the plates, with no pulling or snagging which can be especially damaging for fine hair.
Dylan also loves this Karmin iron. "The plates are coated in tourmaline which helps for an easy glide," he says. Fighting frizz with infrared ions, Dylan suggests that it "makes this iron better for super coarse hair." Bonus points: it also has different voltage settings for international use. The jetsetter in you will be thankful as you globetrot glamorously.
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!

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.

The Bio Ionic worked well on all of our testers’ hair, but it’s best on drier hair with a medium thickness. We spritzed testers’ hair with some keratin smoothing treatment, but the Bio Ionic did a lot of the heavy lifting to make our hair feel softer. The tool gets hot, but not too hot to grip, and it excels at creating the silky volume you want without making your hair pin-straight and flat. One tester put it perfectly: “[The Bio Ionic] is the Rumplestiltskin of hair straighteners. It’s turning straw into gold.”

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!
The plate material you choose can also make a big difference on your style results. Ceramic, titanium, and tourmaline are the most common terms you'll come across. Ceramic plates hold heat well and provide even heat distribution, preventing any hot spots on the plates can cause damage. Ceramic is especially effective for fine hair that can be especially vulnerable to heat damage. While many hair straighteners have ceramic coated plates, plates made entirely from this material are more effective, as this coating can wear off over time. Tourmaline is a gemstone, but when crushed and used to coat the plates of a hair straightener, it has properties and results similar to ceramic plates.

The digital interface accurately displays the fully adjustable temperature setting from 170 degrees to 450 degrees Fahrenheit, providing optimal performance for any hair type. The floating plates with curved edges continuously adjust the tension and angle of the plates to avoid snagging your hair so that you have full flexibility when creating sleek, wavy or curly styles.
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.
If you're still not convinced, then ask yourself a question. Ask yourself how serious you are about your lifting. Decide for yourself, right here and right now, whether you're the kind of lifter GRAY HAIR AND BLACK IRON was written for. If you're not, that's fine. No hard feelings. I said at the beginning that GRAY HAIR AND BLACK IRON was written for a very small, very elite group of men and women. It's not mass-market stuff, and it's not for everyone. It's for deeply committed, deeply serious Iron Warriors - warriors who've been battling the iron for a very long time - and who intend to keep on fighting the fight for many years to come. So if that's NOT who you are, don't order the book.
