Skincare-inspired bond repair for seriously damaged hair. L'Oréal Professionnel Serie Expert Absolut Repair Molecular Rinse-Off Serum is an exclusive, highly-concentrated treatment designed to go beyond surface repair. When hair is damaged, its peptide-based molecular structure is compromised, and most peptides are too big to be reintroduced into the fibre. L'Oréal's research decomposed peptides to deliver their components separately, so this serum, packed with 2% Peptide Bonder and 5 amino acids, works to help repair the look and feel of molecular damage and restore the hair's strength, elasticity and movement*. Its serum-like texture absorbs quickly with no heaviness or superficial coating, and hair is instantly transformed, with dramatically improved shine and smoothness*****. For all damaged hair textures, colour-treated, lightened and natural.

What it does for your hair

Damage weakens the hair's internal structure, which is what leaves it feeling brittle and rough, and this serum is L'Oréal's advanced answer to that. Its 2% Peptide Bonder and amino acid blend are designed to work at a deeper level than a surface treatment, helping to repair the look and feel of the hair from within and restore its strength, elasticity and movement, so hair feels genuinely stronger and more resilient rather than just conditioned on the surface. Because its texture is serum-light and absorbs quickly, it does all this with no weigh-down and no coating, so fine and damaged hair alike feels transformed rather than heavy. Used as part of the routine (shampoo, rinse-off serum, leave-in mask), it dramatically improves shine and smoothness, so hair looks visibly healthier and glossier.

How to use it

After shampooing, apply the serum to clean, towel-dried, damp hair, distributing evenly from mid-lengths to ends. Leave on briefly to let it absorb, then rinse thoroughly. Use as part of the Absolut Repair Molecular routine, ideally with the matching shampoo and leave-in mask, for the best cumulative results. Suitable for regular use on damaged hair.

Who it's for

This one's for anyone with damaged, over-processed, bleached or colour-treated hair who wants a concentrated, skincare-inspired repair treatment that goes beyond a standard mask. We've been perfecting colour, blow-dries and styling for clients in Codsall for years, and a good bond-repair routine is one of the best things you can do for hair that's been through a lot.

Build your routine

Bond repair works best as a full routine, so pair the serum with the matching Absolut Repair Molecular shampoo and leave-in mask. Find the shampoo in our shampoo collection, explore more repair and bond treatments across our hair products, or browse our shop by brand pages for your favourites.
