A powerful five-minute reconstructor that rebuilds and strengthens stressed, physically and/or chemically treated hair. Lost or depleted amino acids are replenished with a high concentration of Quadramine Complex for maximum reconstruction and protection from the cuticle to the cortex. Weak and damaged hair is restored to its original strength and condition, helping to prevent colour loss and making your hair more responsive to styling. To use: Apply to damp hair and comb through to ends. Rinse thoroughly after 5 minutes. Can be used as part of your normal haircare routine, 1-3 times per month.
