About L'Oréal Professionnel

L'Oréal Professionnel is the salon division of French beauty giant L'Oréal, with more than a century of haircare expertise behind it. The Série Expert range is the brand's salon backbone — performance-led shampoos, conditioners, masks and treatments designed for specific hair concerns. Absolut Repair is the flagship damage-repair line, and the Molecular Pre-Treatment is the newest, most concentrated step in the protocol.

Key benefits

• Molecular repair: 3% peptide bonder works alongside five amino acids (glycine, glutamic acid, arginine, serine, tyrosine) to rebuild the hair's macromolecular structure.
• Visibly stronger hair: Improves the elasticity, resilience and natural movement of damaged fibres.
• Two years' damage repaired in one application: Brand clinical claim, based on internal performance testing.
• Layerable with the routine: Designed to be used as a pre-shampoo step on damp hair, before the rest of the Absolut Repair routine.
• Clean formulation: Free from sulphates, parabens, silicones, alcohol and added fragrance.

Key ingredients

• Aminopropyl Triethoxysilane: A silane bonder that helps reinforce broken bonds.
• Amino acids (Glycine, Glutamic Acid, Arginine, Serine, Tyrosine): Structural building blocks of keratin — supply the raw materials for fibre repair.
• Citric Acid: pH-balancing acid that helps the cuticle close after treatment.

Who it's for

This pre-treatment is best suited to anyone with significantly damaged hair from bleaching, colouring, chemical services or frequent heat styling — particularly those whose hair has lost springiness, breaks easily or feels rough. Suitable for use in the salon as part of a professional service, or at home as part of a structured Absolut Repair routine.

How to use

1. On damp, towel-dried hair, dispense 15–20 pumps depending on hair length.
2. Spray onto the mid-lengths and ends. Avoid the scalp.
3. Smooth through the lengths section by section for 1–2 minutes, working into each strand.
4. Do not rinse. Continue with the rest of the Absolut Repair routine — shampoo, conditioner or mask, then style as usual.
5. Use as needed for severely damaged hair; weekly for ongoing maintenance.

Size: 190ml. For external use on hair only.
