THE TOURMALINE PARTICLES, ADDED TO THE CERAMIC COATING OF THE STRAIGHTENING PLATES, GENERATE A FLOW OF NEGATIVE IONS DURING THE HEATING PROCESS THAT REDUCES STATIC ELECTRICITY ON THE HAIR, LEAVING IT SILKY, SMOOTH, AND SHINY. IN ADDITION, THE HEAT SPREADS EVENLY OVER THE SURFACE AND MAINTAINS THE INTEGRITY OF THE HAIR. ADJUSTABLE FROM 130°C TO 230°C.
