There comes a point with long hair where it’s not solely about how far down your back it reaches – you want it to look thick and healthy from root to tip. If that’s sounding familiar, try the L’Oreal Professionnel Serie Expert Pro Longer Crème. Like the rest of the Pro Longer range, this leave-in treatment has been formulated to fortify and add volume to long hair, meaning your hair feels stronger and looks healthier. Too good.
