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.”
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!

GHD’s “styler” is permanently set to 365 degrees Fahrenheit, which the company says is the highest temperature hair can tolerate before it becomes damaged. As a person who went from a dark brunette to blonde highlights, I can vouch for its straightening power on processed hair. And though I don’t typically think of “comfort” as a flat iron necessity, the springy hinge that connects the two plates really did make it easier to clamp and glide the tool down my hair with minimal effort.
For some people, automatic shutoff is a critical feature since forgetting to unplug your flat iron could lead to a fire. However, others aren’t fans of auto shutoff since that means their flat irons could turn off while they’re still styling their hair. If this is the case for you, we recommend investing in a timed switch. That way, you can program the switch to turn off at a specific time and your flat iron will shut off as well.
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.
Can a single book add 10 - 20 -30 or even 40 more years to your lifting career? GRAY HAIR AND BLACK IRON may do exactly that! We won't know for sure for another 30 or 40 years - but anything that helps older lifters preserve and protect their joints, maintain their mobility and athleticism, avoid overtraining and reduce the risk of injuries may very well help you to keep lifting for a very long time - and if you're like me, that means the information in the book is literally priceless. And at $34.95 plus shipping, that makes GRAY HAIR AND BLACK IRON the bargain of the year.
Before explaining the advantages, let’s discuss the heating process. Flat Iron does the basic purpose of heating so that the hair follicles can flatten. Flattening of follicles is needed to create any hairstyle. Hair follicles contain natural moisture. When we heat the hair, the natural moisture gets eliminated. That’s why hair ends up with the rough texture.
For such a high-end flat iron, we were disappointed that the Babyliss doesn’t have a precise temperature display like the Bio Ionic. Our testers were confused by the settings, which had numbers going up to 50 vs. actual temperatures. The numbers represent a range, but you have to look through the instruction manual to figure out what that is. One tester summed it up perfectly: “I don’t want to read an instruction manual to use a hair straightener.”

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.
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.
If you have very thick, curly, or coarse hair, you may be wondering if xtava’s Infrared Flat Iron for hair can handle the job of hair straightening your locks - and we have good news for you. Our hair straightening iron has two key characteristics that equip it for the job: high, consistent, and even heat that can lock in your style and extra-wide, 2” floating plates that can handle a lot of volume.
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!
I ABSOLUTELY LOVE this hair straightener/curler. I was looking into buying the new TYME Iron that came out but found this one that was so similar and more than half the price. After seeing some reviews, I trusted it enough to purchase it. Got it in today and curled my hair (WITH my clip-on hair extensions) and it not only curls/straightens SO pretty but leaves hair nice and soft and silky AND therefore made my extensions blend in so so seamlessly. If you're looking for a new straightener/curler, I absolutely recommend!

“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.

When you apply heat to your hair, which is not a living thing, you’re essentially cooking it. And, just like food, it’s easy to overdo it. Short of actually searing your hair, you still run the risk of drying out each strand, which can lead to breakage and split ends over time. Every head of hair is different, and each type of hair has an optimal flat-iron temperature. Some locks need extremely high temperatures to relax — coarse hair or those with kinky hair need 380 degrees F or above. Others need hardly any heat at all — fine or damaged hair should be good below 300 degrees.

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.

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.
