Strengthen your hair from the inside out with the Schwarzkopf Professional BC Bonacure Fibre Force Sealer, an intensive reconstructing milk for damaged hair types. Created for those whose hair has been damaged from heat styling or chemical treatments, the Fibre Force Sealer creates bonds inside the hair follicle to strengthen each str&, revealing a smoothed, soft texture to your hair that lasts. A Bond Connector Service seals each cuticle, providing each strand with a protective shield. When used as part of a BC Fibre Force routine, this refortifying sealer makes sure your hair looks shiny, healthy & full of bounce. Massage into the mid-lengths & ends of towel-dried hair & comb through.
