Catering specifically for thin, lack-lustre locks, the Matrix Biolage Full Density Shampoo works to leave hair feeling thicker and healthier. Formulated with Biotin, Zinc PCA and Gluco-Omega, the lightweight shampoo gently cleanses to eliminate impurities, unclogging the hair follicles and minimising breakage to reveal stronger, fuller locks with increased density. Adds volume from root to tip for big and bouncy results around the clock.
