L'Oréal Professionnel's Pro Longer shampoo helps to thicken long hair whilst making it visibly healthier and stronger looking. When used with the Pro Longer conditioner for long hair, there is a 44% hair breakage reduction and split ends are reduced visibly by 20%*. The unique Filler A-100 technology works by penetrating the fibre core to plump and thicken the hair from the inside. Amino acids in the formula work to strengthen the hair from the outside. The formula works on thin ends, or areas where help is most needed.


  • 94% hair breakage reduction
