Schwarzkopf Professional's Bonacure R-TWO Renewal Sealer is an instantly strengthening and protective leave-in hair mask specially developed for extremely damaged hair caused by over-processing or stress. Above all, chemical treatments, such as dyeing or bleaching, and the frequent use of heat tools strain the hair and make it more prone to breakage.

The leave-in hair mask strengthens stressed hair and repairs the fibres to preserve their integrity. The double bonding technology creates new fibre connections and forms a protective shield against renewed damage. Nourishing ingredients are deposited on even the most porous parts of the cuticle. This restores a smooth, strong and even surface.
