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!

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. 
While temperature control is typically a good thing to have in a hair straightener, it can also result in hair damage if you're keeping the temperature too high. The GHD Gold eliminates the chance of any user error, operating at an even 365 degrees Fahrenheit. This is the optimal temperature for most hair types, getting you smooth results without damaging your hair. The gold coated ceramic plates heat up quickly and maintain an even temperature, eliminating the chance for any hair damaging hot spots as well.

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.
