Discover a new era of professional hair repair with Absolut Repair Molecular Pre-Treatment, a scientifically advanced solution designed for damaged hair in need of deep, structural restoration. When hair becomes severely damaged—whether through colouring, lightening, heat styling, or other chemical processes—its internal molecular structure, made up of peptides, breaks down. Conventional treatments often fall short, as most peptides are too large to reintroduce into the hair fibre.

Now, thanks to a major scientific breakthrough, L’Oréal’s Advanced Research team has succeeded in deconstructing peptides into their essential components—allowing them to penetrate the hair fibre and reassemble within for molecular-level repair. This patented pre-treatment, concentrated with 3% Peptides bonder and five essential amino acids, works from the inside out to restore the hair’s strength, resilience, and natural movement.

Designed with professionals in mind, this innovative formula offers far more than surface repair. Its lightweight liquid texture allows for rapid absorption without weighing the hair down, making it ideal for salon services across all hair types—whether colour-treated, lightened, or natural.

The result? Instantly transformed hair that is smoother, more supple, and easier to detangle. Developed in collaboration with global repair specialists, the Absolut Repair Molecular range represents the future of targeted, professional hair restoration.

How to Use

On damp hair, spray evenly from mid-lengths to ends.
Use 15 to 20 pumps, adjusting to the length and thickness of the hair.
Work the product through each section using a smoothing motion.
Massage gently into the lengths and ends for 1–2 minutes. Do not rinse.
Layer directly with Absolut Repair Molecular Shampoo over the top, then rinse thoroughly. Follow with the Absolut Repair Molecular Rinse-Off Serum to complete the treatment.
Avoid contact with eyes. In case of contact, rinse immediately and thoroughly.

Sustainable Tip: This is a no-rinse step—keep the tap off during application to help reduce water consumption.
