L’ Oreal Serie Expert Lumino Spray Bi-phase should be your secret weapon if you have a head of highlights you want to keep looking fresh. This is the ultimate highlight-enhancing product from L’ Oreal. Enriched with xylose, Serie Expert Lumino Spray Bi-phase works in two ways: first, it moisturises the highlighted areas which are prone to dryness. Secondly, it protects your hair from the damage heat styling can cause. This is a must for anyone with highlights that need brightening.
