Daily styling, environmental stressors, and repeated washing can weaken hair over time. Vichy Dercos Collagen Filler 17 is an ultra‑repairing pre‑shampoo treatment designed to help reinforce the hair fiber and improve the appearance of damaged, breakage‑prone hair.
The advanced formula combines pro‑collagen peptides and citric acid to help visibly fill micro‑damage within the hair fiber, leaving hair stronger and more resilient over time.
Used before shampooing, this treatment helps reduce the appearance of breakage, improves softness, and leaves hair feeling smoother without weighing it down. Its lightweight texture absorbs easily and rinses out effortlessly.
Suitable for sensitive scalps, Dercos Collagen Filler 17 is the perfect first step in a restorative hair care routine.
