VICHY Dercos Collagen Peptide 17 Deep Conditioner 6.76 oz — strengthens, seals & reduces breakage

Dercos Collagen Peptide 17 Deep Conditioner is a final-step treatment that nourishes and seals hair to strengthen strands and reduce breakage for visibly fuller, healthier-looking hair.

As scalp collagen naturally declines and environmental stressors accumulate, hair fibers can become fragile and more prone to snapping. VICHY’s Dercos Collagen Peptide 17 formula was created to address fiber weakness by rebuilding and reinforcing the hair structure. Used as the finishing step in the brand’s Ultra Repairing 3-step routine, this conditioner helps smooth, nourish, and lock in the benefits of the pre-shampoo treatment and shampoo to deliver long-lasting resilience and improved appearance.

How does this conditioner help hair that breaks easily?

The conditioner contains targeted ingredients that work to strengthen the hair fiber after the scalp and strand-focused steps that come before it. It helps close the cuticle, reduce friction between strands, and fortify weakened bonds so hair resists snapping during brushing and styling. Regular use as the concluding step enhances manageability and reduces visible signs of damage.

• Contains Collagen Peptide 17 to enhance fiber thickness and resilience
• Formulated to complement the pre-shampoo bonding and ultra-repairing shampoo
• Smooths and seals strands for easier detangling and less friction
• Designed to leave hair soft, manageable, and visually fuller

What key ingredients make a difference in repair?

Dercos combines Collagen Peptide 17 with Citric Acid to target different aspects of damaged hair. Collagen Peptide 17 focuses on rebuilding the strand’s structure and improving thickness, while Citric Acid helps repair weak bonds within the fiber and improves the hair’s surface. Together they act to restore a healthier look and feel without weighing hair down.

• Collagen Peptide 17: strengthens and reinforces fiber core
• Citric Acid: helps repair internal weak bonds for improved integrity
• Conditioner base: nourishes, smooths cuticles, and adds slip for detangling

How do I use this as part of the Ultra Repairing system?

The conditioner is intended as the third and final step in VICHY’s specified sequence to maximize repair. Start with the Pre-Shampoo Treatment on dry hair to prime and bond strands, layer the Ultra Repairing Shampoo over it without rinsing to allow active ingredients to work together, then finish with this conditioner. Applying in that order helps lock in treatment benefits and finishes the hair surface for lasting softness and strength.

• Step 1: Apply Pre-Shampoo Treatment to dry hair to bond strands
• Step 2: Apply Ultra Repairing Shampoo over treatment without rinsing
• Step 3: Rinse and apply the Deep Conditioner as the final step to nourish and seal
• Use regularly for cumulative reduction in breakage and improved manageability

What visible results can I expect and how quickly?

When the full 3-step Ultra Repairing system is used consistently, users report a significant reduction in breakage and improved hair fullness and smoothness. While individual results vary, the system is formulated to repair multiple signs of damage and progressively strengthen strands. Continued use maintains the rebuilt structure and improves the overall look and feel of hair.

• Targets multiple signs of damage to improve overall hair appearance
• Designed to reduce breakage and enhance resilience with repeated use
• Leaves hair softer, shinier, and easier to style

Who this is for: This conditioner is intended for people experiencing hair breakage and thinning due to weakened fibers, environmental stress, or age-related scalp collagen decline. It suits anyone following the Dercos Ultra Repairing regimen who wants a strengthening, finishing treatment that smooths and nourishes without compromising volume. Ideal for those seeking a dermatologist-backed option to reinforce hair structure and improve manageability.
