The Tourmaline injection process reduces the static electricity of the hair. The cuticle layer of each hair will be closed and therefore effectively prevent the hair from drying out. This results in a healthy, radiant shine and an easier styling. Ionized brushes offer the best protection, especially for frequent hair drying or the use of heat-based technologies.
