Maintaining long hair is a challenge. Long hair lovers always had to choose between hair health, thickness, and length. At the salon, hairdressers have to cut their clients hair because the longer the hair, the thinner the ends. Hard-cutting used to be the only way to give an even thickness from root to tip. Not anymore! L'oreal Professionnel presents Serie Expert Pro Longer range that renews lengths, fills-in ends and visibly reduces split ends by 94% so you can keep the long hair you love. For longer, thicker, better hair.
