A salon mask that rebuilds damaged hair from the inside
L'Oréal Professionnel Absolut Repair Molecular Mask is a professional repairing mask for damaged and chemically treated hair. When the peptides that make up the hair fibre are damaged, hair becomes weak, over-elastic and loses its movement, yet most peptides are too large to get back inside the fibre. L'Oréal's patented approach breaks them down and delivers their building blocks separately, so they can reassemble inside the hair. Its Peptide Bonder works with five amino acids (glycine, arginine, serine, tyrosine and glutamic acid) to help rebuild the internal structure and restore strength and elasticity. Hair is up to 86% smoother, easier to manage and moves naturally again.
The texture
A rich, creamy mask that coats each strand evenly and rinses out after just one to two minutes. It nourishes without weighing hair down.
Who it suits
- Severely damaged, weak or over-elastic hair
- Bleached, coloured or chemically treated hair
- Hair with split ends and heat damage
- Thick hair that needs rich care on every wash
Worth knowing before you buy: The formula contains silicones and fragrance. On fine hair, use it once a week and keep it to the lengths and ends so the roots stay light.
How long one jar lasts
Used on every wash day on medium-length thick hair, the 250ml jar lasts about two months. Used once a week on fine hair, it lasts four months or more.
