While traveling in Japan, internationally renowned hair sensei Fernando Romero did a little more than admire the scenery. After discovering the power of natural negative ions emitted by post-volcanic rock (which had a strengthening effect on locals when sipped in their water). It dawned upon Romero that this rock's minerals could yield big beauty benefits. Before long, Bio Ionic was born, the brand's ion-infused brushes, dryers and other strand-smoothers better able to help their users look fabulous due to their ability to break down water molecules on the surface of their locks and allow deeper penetration into the hair shaft. The result? Smooth, shiny, hydrated hair in the blink of an eye.
