NanoIonic MX Technology
NanoIonic MX is Bio Ionic's signature mineral complex. It emits negative ions during styling. The ions break water into tiny hydrating particles. These particles penetrate the hair shaft. Hair stays moisturized through heat styling. The result is shinier, bouncier curls. Users report less dryness over time. The technology sets Bio Ionic apart from standard irons.

The 1.5 inch barrel creates looser, softer curls. It suits long hair wanting relaxed waves. The same NanoIonic tech applies. Heat and safety features match the 1.25.
