Ionic Technology
Ionic hair dryers incorporate a new technology that has taken the hair care market by storm. The technology allows hair dryers to fully restore and fortify hair by providing it with the ability to absorb more moisture than if left wet. It does this by emitting a large number of microscopic ions that break down water molecules for absorption in the hair, without the use of high amounts of air-blown heat to dry hair out.
How It Works
Water droplets are composed of hydrogen and oxygen atoms. This molecular compound (H2O) is considered an ion because it has an uneven number of protons and electrons, with a positive ionic charge due to its excess number of protons. Water's adhesive and cohesive properties cause it to form large water particles that aren't easily absorbed by the hair. An ionic hair dryer creates negative ionic charges inside the hair dryer and blows them out into wet hair (regular hair dryers, in contrast, release positive ions). The negative ionic charges are attracted to the positive ones in the hair, and break up the cohesiveness of the water droplets into one-fiftieth of their normal size. This reduces the size of the water molecules so they can then be more easily absorbed by the hair. This allows hair to utilize the water in the hair, rather than evaporating it out like a normal non-ionic hair dryer would.
Benefits
Ionic hair dryers provide faster hair-drying times and improve hair health as well. Non-ionic hair dryers are not capable of drying hair as quickly, subjecting hair to longer heating times and higher heating temperatures; these two factors--higher heat and longer heating time--can cause extensive damage to the hair cuticles themselves, leaving your hair frazzled, frizzy and significantly drier.
