Ions are atoms that have gained or lost an electron and bear a charge of energy. Positive ions have lost an electron and are considered unhealthy. They are found in dust, smoke and other toxic substances. Negative ions have gained an electron and greatly assist in a body's mood, energy level and overall health.Bio Ionic Professional Hair Care System utilizes technologically advanced Natural Ion Complex to deliver natural negative ions to the hair. Natural negative ion energy is powerful enough to break water molecule clusters into micro-fine particles (atomization) and penetrate the hair shaft. That means moisture balance is restored and the hair cuticle is sealed.The results achieved with Bio Ionic Professional Hair Care System products are immediate. The hair is renewed, repaired and revitalized for a softer, smoother, shinier finish.
