A professional mask that rebuilds damaged hair from the inside
L'Oréal Professionnel Série Expert Absolut Repair Molecular Mask is a deeply reparative rinse-off mask for damaged hair. When the hair's inner structure, made mainly of peptides, is broken down, hair turns weak, overly elastic and limp. L'Oréal's research created a peptide bonder that enters the fibre in small parts and reassembles inside, working with five essential amino acids to rebuild the hair's molecular structure. Strength, elasticity and movement come back, and hair is up to 86% smoother and easier to manage.
The texture
A creamy mask that coats each strand evenly and nourishes without weighing hair down, even on thick, chemically treated hair. It detangles easily and rinses out cleanly, leaving hair soft, supple and full of natural movement with a salon-style fragrance.
Who it suits
- Damaged, weakened or over-processed hair
- Bleached, coloured or heat-styled hair
- Hair that feels limp, rubbery or breaks easily
- Split ends and rough lengths
Worth knowing before you buy: The formula contains silicones and fragrance. On fine hair, use it once a week and on the lengths only so it does not weigh hair down.
How long one tube lasts
Used once a week on mid-length hair, the 150ml tube lasts around 2 months; less on thick hair used every wash.
