Early hair straightening systems relied on harsh chemicals that tended to damage the hair. In the 1870s, the French hairdresser Marcel Grateau introduced heated metal hair care implements such as hot combs to straighten hair. Madame C.J. Walker used combs with wider teeth and popularized their use together with her system of chemical scalp preparation and straightening lotions.[3] Her mentor Annie Malone is sometimes said to have patented the hot comb.[4] Heated metal implements slide more easily through the hair, reducing damage and dryness. Women in the 1960s sometimes used clothing irons to straighten their hair.
According to Jarman, you should never have to use both hands to clamp the iron down on your hair. You not only risk burning your fingers on the plate end, but this can pull at your hair and break it. High-quality, modern irons are designed to clamp together from the handle end only, so if you find that your iron requires pressure on both ends, it’s time to upgrade.

Our two testers with kinky and thick hair loved the Chi Air Expert Classic Tourmaline Ceramic Flat Iron. In fact, it was each of their top picks, with the Bio Ionic coming in second. The Chi Air reaches 410 degrees F, which is definitely hot enough for thicker and curlier hair types. The speed at which the tool worked was surprising considering the kinkiness and thickness of both testers’ hair. One tester with long, curly hair had to leave early for an event and needed to finish styling. The Chi Air moved through her hair quickly, giving her time to spare. And, even at 410 degrees, our testers didn’t feel like their hair was being fried or that the heat burned their heads. In fact, they complimented how soft it made their hair feel and how comfortable it was to use, unlike the NuMe Megastar which snagged a lot or the HSI Professional Glider which felt hot against their scalps. As one tester said, “Chi is killing it.”
Do you have curly, dry hair? Thick, color-treated hair? Short, straight hair? Fine, kinky hair? Finding the right flat iron for you really depends on your hair type. Heat and plate types are an important factor in this. Your flat iron should reach and maintain the right temperature and be made from the plate material that works best for you. While most will work well on a variety of hair types, pay close attention to reviews from people with hair similar to yours (bonus points if they include before and after pictures).

Nearly 21,000 people gave this flat iron a five-star review on Amazon. If they factored price into that rating, then I agree. For less than $60 it’s pretty spectacular, but it doesn’t beat the fancier ones in terms of performance. The temperature automatically drops after 15 minutes of use. And while it’s easy to adjust that, it is also slightly inconvenient.

The ½ inch plates allow the BaBylissPro Mini to get close to the scalp, so it will straighten hair from root to tip. It's lightweight and compact at 6 inches long, so it will fit easily in a purse or carry-on bag with no hassle. It comes with a heat resistant travel pouch for storage so you can pack up and go at a moment's notice before or after straightening your hair.
Lifters who are deadly serious about their training, and who prove it by doing the serious exercises - the BIG movements -- exercises like squats, front squats, bench presses, barbell bent-over rowing, deadlifts, Trap Bar deadlifts, standing presses, push presses, power cleans, power snatches, and jerks. Lifters who finish every workout covered in chalk and sweat - and who've been doing it that way for a long time.
If you’re looking for an affordable mid-grade hair straightener that offers tremendous value, you can’t go wrong with the HSI Professional Digital Ceramic Flat Iron with Tourmaline. With a quick heat-up, digital LCD temperature control, and solid ceramic plates infused with tourmaline, you can straighten type 3 hair – and some type 4 hair – with ease.
There are a few downsides to the BaBylissPro Mini. For those with longer hair, it may take a little more time to straighten than it would with a normal-sized straightener. It also lacks the 360-degree swivel cord and automatic shut-off found in most full-size hair straighteners. However, these downsides can be overlooked when taking the other features into consideration, like its lightweight, compact size and the fact that it can still hold the same temperatures as a full-sized hair straightener.
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.
If you travel abroad often, you won't have to worry about ruining your investment, either, because the GHD Gold has universal voltage. It also features a generously long 9-foot cord with 360-degree rotation to prevent tangling. The automatic sleep mode shuts off the straightener if it hasn't been used in 30 minutes, so you'll have peace of mind if you forget to shut it off in your morning rush out the door. If something does go wrong, the GHD Gold comes with a 2-year manufacturer's warranty.
If you’ve ever used a CHI hair straightener before, then you’re probably pretty well acquainted with the turn dial temperature control of models’ past. While this dial design made it easy to switch on your hair straightener each morning (even before you have had your morning coffee!), it also made it all too easy to accidentally change the temperature during use.

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.
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.
Ceramic and electrical straighteners were introduced later, allowing adjustment of heat settings and straightener size. A ceramic hair straightener brush was patented in 2013.[6] Sharon Rabi released the first straightening brush in 2015 under the DAFNI brand name. The ceramic straightening brush has a larger surface area than a traditional flat iron.
That is just one of the reasons that hair straighteners are such a wonderful tool to keep in your beauty arsenal; not only does this nifty little device give you movie star-quality straight hair when you want it (sorry blow out bars), but it can even create the same curls as those confusing barrel-ended curling irons! So, clean out your cabinet under the sink and make room for that makeup you’ve been eyeing or the perfume your husband forgot to buy you for Valentine’s Day last year, because a professional-grade hair straightener can literally replace all of your existing heated hair care tools!
If you have ever visited a luxury spa or wellness company, you have probably run across far infrared heat a time or two. Without going into too much science, infrared heat is the same heat you feel when the sun kisses your cheeks and warms your body from the inside-out. Far infrared heat, in particular, has been used by medical and wellness professionals for years to treat a variety of conditions from muscle pain to even cancer.
An upgrade from their since discontinued Eclipse Styler, you won't be tempted to heat this flatiron up to 450 degrees, because the temperature dial is always stuck on one number: 365 (the ideal heat to mold hair without frying it, according to the scientists at GHD). Underneath each of those 365-degree plates are three fancy sensors that measure the density of the hair in the iron so that it can maintain consistent heat regardless of the chunk of hair you grab. The result? Silky, shiny hair with zero frizz.
