As you discover the beauty of straight styles, you'll want to find the best hair straightener that won't compromise your hair and caters to your hair type. Achieve optimal results through the reliable performance, quality, and design of NuMe professional styling tools. The gentle heating of far infrared technology and negative ion-producing, 100 percent pure, tourmaline ceramic plates reveal the conscious and authentic design of NuMe hair straighteners. 
Despite these downsides, the HSI Professional comes with plenty of positives, including extras not often found with other hair straighteners. Along with the straightener, you'll receive a carrying case, a heat-resistant glove for easier hair styling, a style guide, and a travel-size argan oil leave-in hair treatment serum to smooth and protect your hair. This is more than most high-end hair straighteners come with, all for a fraction of the price.

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.

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.
Heat stylers, such as flat irons, get a bad rap for singeing hair beyond repair, but that doesn't have to be the case. The key to preserving your hair's health while using these hot tools is passing a quality straightener over heat-protected strands without letting the heat sit on one spot too long. Speaking of stellar straighteners, here are 11 of our top picks, ya know, if you're looking to upgrade yours.
If your hair is plagued by tangles and knots on a regular basis (even in between straightening!), try switching your hairbrush out for a wide-toothed comb! The added space in between the teeth gently separately knots and tangles without the painful “Ouch!” with each stroke. If that still isn’t enough to tame your stubborn tresses, try a wet brush! These brushes are specially designed to work through knotted, wet hair without any tugging or pulling.
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 nano ceramic plates in this straightener deliver far-infrared heat, a gentler alternative in and of itself. As if that weren't enough, there's also a reservoir where you can pour in some of the (included) argan treatment and thermal protectant, creating a conditioning steam that will strengthen and safeguard strands while you straighten. Admittedly an extra step, sure, but one that's well worth it.
