L'Oréal Professionnel Pro Longer Shampoo 1500ml is a transformative hair care product that not only thickens your long hair but also enhances its overall health and strength. When used in conjunction with the Pro Longer Conditioner, it delivers impressive results - reducing hair breakage by 44% and visibly diminishing split ends by 20% through the innovative Filler A-100 technology. This cutting-edge formula works deep within the hair fiber to plump and thicken from the inside, while fortifying amino acids strengthen the hair externally, particularly focusing on areas that require the most attention.
