Density Defend Hair Booster Serum

As a targeted hair serum from Nioxin, Density Defend Hair Booster Serum aims to support scalp health and visibly fuller-looking strands. The lightweight, non-greasy liquid layers easily under styling products and suits those with thinning hair or fine textures seeking extra density. Recommended for daily use, it blends into routines and pairs well with leave-in treatments.
