Did you know that hair fiber thickness and resilience to breakage can be compromised by several internal and external factors, such as the scalp’s collagen breakdown? That’s why hair fall due to breakage becomes more common over time. Dercos Collagen Peptide 17 Ultra Repairing System was designed to fight hair fall due to breakage by fortifying the hair and helping repair 17 signs of this damage for 73% less breakage. Our system strengthens weak bonds with Citric Acid and Collagen Peptide to leave the hair more resilient, visibly fuller and healthy-looking from root to tip. This 3 step routine works together to build strength at every step. Prep & bond hair with the Pre-Shampoo Treatment, before cleansing with the Shampoo and nourishing & finishing with the Conditioner. Use this Ultra Repairing Pre-Shampoo Treatment as a first step, apply to hair & scalp and leave on for 5 minutes for best results. Did you know that the scalp is also skin? Dercos treats your scalp the same way you treat your skin. As the No. 1 dermatologist recommended haircare brand in Europe, we are on a mission to break taboos around dandruff to promote a healthier feeling scalp & hair for all. KEY INGREDIENTS CITRIC ACID: An Alpha-hydroxy acid (AHA), one of the smallest molecules to penetrate the fiber cortex and recreate weak bonds COLLAGEN PEPTIDE: A biosynthetic collagen peptide similar to a protein fragment found in collagen. | Vichy Dercos Collagen Peptide 17 Ultra-Repairing Treatment, 5. 07 fl. oz | Dermstore
