For the first time, L'Oréal's advanced researchers have successfully split peptides by injecting their components separately into the hair fiber. Once inside, these components reassemble to reconstruct the macromolecular structure of the hair. The serum texture is quickly absorbed by the fiber, providing molecular repair without adding weight to the hair.

For optimal results, use the serum after using Absolut Repair Molecular shampoo, and make sure to detangle your hair beforehand for optimal absorption. Divide your hair into two sections. Take 2 to 3 pumps of the product into your hands and distribute them evenly in your palms. Apply the serum to each hair section, from roots to ends, on wet hair. If your hair is very dry, you can apply the product from roots to ends. Massage each section between your hands for 1 to 2 minutes. Run your fingers through your hair to detangle it perfectly. There's no need to let the product sit for a certain period as its effectiveness is immediate.
