Developed to visibly volumise, the Philip Kingsley Density Thickening Shampoo gently cleanses the hair while encouraging a fuller look. Powered by hyper-branched polymers and hydrolysed pea peptides, the formula promotes a stronger feel, alongside replenishing lost moisture and diminishing the appearance of dry, brittle strands. Salicylic acid lends mild exfoliating action, buffing away dead skin cells and flakes from the scalp, and providing a more optimal environment for normal hair growth.
