R+Co Bleu F Layer Deep Conditioning Serum

R+Co Bleu F-Layer Deep Conditioning Serum

Healthy hair starts here. This lightweight, invisible post-shampoo serum is the essential first step to healthy, shiny strands. F-Layer Deep Conditioning Serum works on the crucial F-layer—a protective lipid layer responsible for retaining moisture and giving hair its natural smoothness, shine, and light reflectivity. The formula is lightweight yet deeply nourishing—it moisturizes, rebuilds, and perfectly prepares hair for any style.
