CRIOXIDIL Macadamia Serum with macadamia oil has an intensely nourishing effect on the hair. Not only it repairs split and damaged ends but also leaves hair spectacularly shiny, deeply hydrated and frizz-free. Doesn’t cause matting or build-up. A natural oil extracted from the macadamia nut, with a composition similar to that of the scalp’s lipid layer. Adds shine and offers the hair natural protection, especially after chemical processing treatments.
