Chemical processing, colour-treating, heated styling tools and heavy-handed brushing, can all cause the bonds inside the hair to weaken and break, and when the internal structure of the hair is compromised, strands are more prone to snapping and splitting. Damaged tresses require targeted treatment to reinforce, repair and restructure these bonds, to help hair become stronger and healthier once more, and able to retain moisture for longer. Applied before shampooing, Bond Builder Restructuring Treatment strengthens existing bonds inside the hair while repairing broken ones, helping to restore hair health and turn back time on damage. WHY YOU’LL LOVE IT: This one-step treatment fits easily into every hair care regime, without the need for any further steps or specific in-salon activation. Starring Advanced Bond Rebuilding Technology, the innovative formula works within the hair shaft, to repair, strengthen and shield bonds from damage. Bestowing results that last several washes, it works by protecting existing bonds and reconnecting broken ones. Tresses are left stronger and more resilient against damage, with strength improving use after use.
