the ideal balance between intense bleaching and hair fiber protection. Up to nine levels* of hair lightening are possible, and the PLEX Technology lessens the harsh effects of the persulphates, shielding the hair from harm for the duration of the application. Suggested for colored or natural hair. Without putting undue strain on the hair fiber, a double application lightens hair up to nine levels. PLUS: Unique texture that doesn't shed or dry out, perfect for all lightening services.
