The Vichy Dercos Collagen Filler 17 Repair Treatment for fine hair prone to falling out is a targeted hair care solution designed to address specific hair issues. This 150 ml balm formulation combines citric acid and collagen peptides in a sulfate-free composition to strengthen weakened hair fibers and promote density and vitality. The treatment penetrates the hair cortex to repair weakened connections within the hair structure, resulting in reduced hair loss and less breakage. Suitable for all scalp types, this product is particularly effective for fine, damaged, thinning hair and hair prone to falling out, including colored and chemically treated hair. The formula nourishes tired lengths and promotes stronger, fuller-looking hair without unnecessary weight or residue. For optimal results, apply after washing hair with the corresponding shampoo from the same line, evenly distribute through the hair lengths, leave on for 5 minutes, and rinse thoroughly. This treatment represents the third step in the comprehensive Vichy Dercos Collagen Filler 17 three-step system, which includes a pre-shampoo treatment and a shampoo for a complete hair care program. The product offers practical benefits such as strengthening hair, reducing breakage, and improving hair appearance from root to tip, with a focus on measurable improvements in hair quality and resilience.
