Living Proof Scalp Care Density Serum is a lightweight, non-greasy serum designed to support fuller-looking hair by improving the appearance of thinning over time. Applied directly to the scalp, it helps reduce shedding and minimize gray hair while promoting healthier hair growth. The formula includes antioxidant and amino acid blends, amaranth peptides, and other botanical extracts to enhance hair density and strength. For best results, use daily on dry or damp scalp without rinsing.
