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.
Heat levels are most important, and everything else is tied for second place. The true benefit of these appliances is that lower temperatures are suitable for easily-damaged or thin-to-medium hair, so it’s crucial that they’re able to operate at the appropriate temperatures. 365° is considered optimal for medium-thick hair, and straightening very thin or brittle hair calls for temperatures closer to 300°. Some models also have settings as high as 450° for use on very thick or very curly hair.
