epres™ Bond Repair Treatment is a patented, science-forward bond builder for hair. It’s the only treatment on the market that uses Biodiffusion™ technology, enabling it to continue transforming the hair long after it dries. The molecular technology repairs disulfide bonds, which form the internal structure of healthy hair. Its formula actively re-bonds hair’s structure adding lasting softness, strength, and manageability; its unique liquid-molecule technology continues to diffuse repair throughout each strand for hours after application. Rather than multiple steps and products, epres™ Bond Repair Treatment is a single, one-step 4 ingredient acid-free spray that works in just 10 minutes to repair chemical, thermal, and mechanical damage.
