Infrared is part of the natural light spectrum and carries heat. We can’t see it but can feel in the form of heat. Unlike UV light, its wavelengths are inoffensive to skin or scalp. This form or energy, also called electromagnetism or radiation, is different than other forms of heat like conduction (using direct contact) or convection (using liquid, gas or air to transfer heat indirectly). When it comes to hair, the heat of infrared light is proven to travel faster and more directly than traditional convection hair dryer technology. The result is faster hair drying, reduced energy consumption and less exposure to heat which can create hair damage.
