STRENGTHEN: This conditioner forms the third step of the Bond Repair haircare routine. This caring conditioner boosts hair with Citric Acid while sealing the cuticle for maximum care of the hair fibre. Hair is made up of millions of bonds that give it structure and strength. When hair bonds break through brushing, bleaching, heating, and styling, hair becomes weak and damaged. For the first time, our formula powered by Citric Acid Complex targets damaged hair. Hair is restored to its original strength¹. Up to 98% less breakage, 90% more shine & 82% stronger hair². Suitable for all types of damaged hair. ¹ instrumental test after 5 applications of Pre-Shampoo Treatment + Shampoo + Conditioner. ² instrumental test on Pre-Shampoo Treatment + Shampoo + Conditioner.
