The tourmaline ceramic in LibertyGlow works on multiple levels to benefit all hair types. For fine, sensitive strands, the even heat distribution prevents localised damage and breakage. In medium hair, negative ions released by tourmaline neutralise static electricity, significantly reducing frizz. For thick or resistant hair, the constant 200°C temperature efficiently penetrates the hair cortex, allowing lasting transformations with fewer passes. The technology also seals the cuticles during the process, resulting in a natural shine that enhances the colour and health of the strands, regardless of original texture.
