R•4 Intense Bond Repair Leave-In Treatment

R4 is a once-weekly leave-in mask that repairs dry, damaged hair deep into the cortex for stronger, softer, healthier hair after a single use.

Powered by RDS Bond Technology, this bond repair leave-in strengthens, hydrates, and protects hair while reducing breakage by up to 80% after one application.

RDS Bond Technology features hydrolysed wool protein to rebuild disulfide hair bonds. It also includes antioxidants and fruit extracts that boost shine and prevent dehydration. This bond system works to strengthen hair while maintaining softness and movement for healthier-looking hair.

Bond repair leave-in is essential for anyone with damaged hair from heat styling or chemical treatments. If you experience hair breakage, split ends, dullness, or frizz, your hair bonds need repair.

After shampooing, towel-dry hair until damp (not soaking). Apply 1–3 pumps of bond repair leave-in from root to tip, leave for 3 minutes to activate, then style as usual — do not rinse.

R4 works in just 3 minutes, repairing hair bonds while you style. Your hair becomes stronger, softer, and shinier immediately, with up to 80% less breakage and smoother, more manageable strands.

Once a week is sufficient. Regular use of our R4 leave-in treatment ensures continuous bond repair and protection between washes.
