Ultra-Repairing Decalcifying Concentrate is a descaling and repairing pre-shampoo treatment with double repairing action for damaged hair.

Eliminates calcium build-up and rebuilds hair strength*, leaving it stronger, softer and shinier. This concentrate has a clear gel texture .

For greater effectiveness, combine it with Bain Réparateur Décalcifiant.

Calcium from hard water can further damage already damaged/weakened hair. Being more porous, damaged hair absorbs 3 times more calcium from the water than natural hair, and enters a cycle of persistent damage.

The 8% concentration of pure acids in this treatment has a double repairing action: it eliminates the calcium build-up in the hair responsible for breakage and repairs it from the inside by reconnecting the damaged keratin bonds*.

Hair looks stronger, healthier, shinier and more bouncy. Hair regains 99% of its original strength.

Benefits:

  • Dramatically decalcifies and repairs persistent damage.
  • Reverses stiffness and dull tone.
  • Reconnects damaged keratin bonds* to reinforce the internal structure.



How to use:
  • Apply generously to damp hair before shampooing and massage in.
  • Leave on for 5 minutes without rinsing.
  • Apply Bain Première directly to the surface of the hair to maximize its effectiveness.
  • Rinse and apply Fondant or Masque Première.

hitherto unknown results
The use of this pre-bath prepares the hair for the rest of the range and you can already see when applying the bath layer after layer, that when clarifying, the softness of the hair having eliminated the calcium in something else.

THE BEST THING I HAVE EVER TRIED TO REPAIR MY HAIR!
Incredible. You put it on wet hair and then wash your hair without rinsing, the result is brutal. My hair no longer frizzes, it looks new, not damaged and the highlights are perfect.
