A rinse-off serum that repairs damaged hair in place of a mask
L'Oréal Professionnel Serie Expert Absolut Repair Molecular Rinse-Off Serum is a deep repair treatment for damaged to very damaged hair, designed to work at the molecular level of the hair fibre. Its patented formula combines a 2% peptide bonder with 5 amino acids that help rebuild the hair's inner structure, so each strand is strengthened from the inside. It suits natural, coloured and lightened hair, and replaces your usual mask without the waiting time: apply after shampoo and rinse. Hair looks smoother and shinier, with better movement and manageability.
How it works
A fluid serum applied in sections on wet hair after shampoo, then rinsed straight away. It spreads easily through lengths and ends and leaves hair soft without heaviness.
Who it suits
- Damaged or very damaged hair
- Coloured, bleached or lightened hair
- Anyone who skips masks for lack of time
- Weak, brittle lengths and ends
Worth knowing before you buy: It contains fragrance and wheat protein, so it is not suitable for anyone avoiding gluten-derived ingredients in hair care. For strong damage, the brand pairs it with the Molecular pre-treatment and leave-in mask.
How long one bottle lasts
Using 2 to 3 pumps per section after each shampoo, two to three times a week, the 250ml bottle lasts around two to three months.
