Renew your hair’s strength and length with the L'Oréal Professionnel Serié Expert Pro Longer Ends-Filling Treatment. (15ml) Highly concentrated, this treatment packs an intense shot of renewing power. Designed for those with thinning ends or a lack of volume, this innovative technology strives to restore your hair’s strength.

Powered by the brand’s signature amino acid blend, the formula strengthens each hair fibre, starting from the outside before working its way to the core of the follicle for long-lasting repair. Formulated with the brand's patented FILLER-A100 molecule, the liquid helps to enhance the thickness and durability of weakened hair. Transform your crown from thin and weak to thick and lustrous.

Apply to shampooed, towel-dried hair. Leave in 3 to 5 minutes. Rinse thoroughly. Follow with Pro Longer leave in cream.
