VICHY Dercos Ultra-Repairing Bond Repair Hair Treatment 150ml — Pre-shampoo Collagen Peptide to Strengthen Hair

Vichy Dercos Ultra-Repairing Bond Repair Hair Treatment is a 150ml pre-shampoo that rebuilds weakened hair fibers to reduce breakage and leave hair fuller and more resilient.

Hair can become fragile over time from environmental stress, styling, and a decline in scalp collagen. Vichy Dercos Collagen Peptide 17 Ultra Repairing System uses a targeted pre-shampoo treatment step—paired with shampoo and conditioner—to reinforce each strand, repair signs of damage, and improve manageability. The formula centers on Collagen Peptide 17 and Citric Acid to rebuild weak bonds and restore a healthier look and feel from root to tip.

How does this pre-shampoo treatment strengthen hair before washing?

The treatment is applied to dry hair and left on to prime and bond delicate fibers before cleansing. Leaving the product on lets active ingredients penetrate and begin reconstructing the internal structure so the subsequent shampoo step locks in repair rather than stripping active benefits.

• Apply to dry hair focusing on mid-lengths and ends.
• Leave on for five minutes for optimal bonding action.
• Do not rinse; layer the Ultra Repairing Shampoo on top to continue the repair process.

What visible improvements can I expect after regular use?

Used as part of the three-step Ultra Repairing routine, the system targets multiple signs of damage to reduce breakage and enhance fullness. Users report improved strand resilience, smoother texture, and a healthier appearance without weighing hair down.

• Repairs multiple damage signs across the hair fiber.
• Reduces breakage by up to 73% when the full routine is followed.
• Leaves hair softer, easier to detangle, and visibly fuller.

Which ingredients provide the repair action and how do they work?

The formula combines Collagen Peptide 17, a patented peptide aimed at reinforcing fiber thickness, with Citric Acid to help restructure and smooth damaged cuticles. Together they focus on rebuilding weak bonds and improving the hair’s surface for better resilience and shine.

• Collagen Peptide 17: enhances fiber thickness and structural resilience.
• Citric Acid: helps repair cuticle irregularities and improve fiber cohesion.
• Dermatologically developed formulation designed for scalp and hair compatibility.

How do I use this product within the full Ultra Repairing system?

The treatment is the first step: apply to dry hair, wait five minutes, then layer the Ultra Repairing Shampoo over it without rinsing. Finish with the Ultra Repairing Conditioner to seal, nourish, and smooth the hair for lasting strength and manageability.

• Step 1: Pre-Shampoo Treatment on dry hair, 5-minute leave-in.
• Step 2: Apply Ultra Repairing Shampoo over the treatment and wash as usual.
• Step 3: Use Ultra Repairing Conditioner to hydrate and seal ends.

Who is this product for? Vichy Dercos Ultra-Repairing Bond Repair Hair Treatment is aimed at anyone experiencing hair fall due to breakage, weakened strands from styling or environmental damage, and people seeking a targeted, science-backed step to rebuild hair strength. It's suitable for those who want a structured three-step routine that treats both scalp and fiber to improve resilience, fullness, and overall hair condition.
