Negative ions have been a longtime fan favorite in the hair care industry, and it is no surprise that this same technology would appear in our top picks for the best hair straightener. Negative ions have been found to reduce static and frizz while locking in moisture, and the same goes for your hair when you use the CHI Air Expert Classic Tourmaline Ceramic Flat Iron!
Unlike the plain Jane ceramic plates of most hair straighteners, the tourmaline-infused ceramic plates in the CHI Air Expert Classic Tourmaline Ceramic Flat Iron are designed to keep your hair healthy during styling. Specifically, the tourmaline helps to more evenly distribute the heat during use which, in turn, creates a higher number of negative ions for shinier and healthier looking hair with each use. This reduces the static electricity created, meaning you get a sleeker, smoother style.
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.
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.
We don’t know too many people that are using their hair straighteners vertically, but there must be a few since ISA has made a point of clarifying that this model is intended only to be used horizontally, i.e., perpendicular to your hair. According to the manufacturer, using the hair straightener horizontally reduces hair pulling for a more comfortable experience. This may be particularly important to you if your hair tends to knot easily or you have unruly curls and texture.
Eight embedded sensors regulate and evenly distribute the heat on this ceramic iron, minimizing damage and increasing shine and smoothness. With adjustable temperature settings that go as low as 140 degrees (the coolest we've ever seen), it's ideal for anyone with super fine hair, or to smooth out the tiny frizzies around your hairline. It also comes with a lifetime warranty, which is never a bad thing.
