L'Oréal Paris Elseve Total Repair

Damaged hair? Strengthen it with this leave-in hair serum that completes the bond repair routine. For the first time, the bond repair formula is supported by citric acid. Inspired by salon hair care: at a molecular level, there are millions of hair bridges in the hair that determine its structure and strength. When these break due to brushing, bleaching, heat, and coloring, the hair becomes weak and damaged. The formula with citric acid penetrates beneath the hair surface into the inner part of the hair, the cortex, to rebuild broken hair bridges.
