Suitable for fine, flat and thinning strands, Philip Kingsley’s Density Thickening Shampoo encourages a fuller appearance with added volume and lift. Powered by hyper-branched polymers and hydrolysed pea peptides, the formula plumps roots with moisture, without leaving behind any oily residue. Supported by BHAs, it gently exfoliates the scalp to remove product build-up and impurities, leaving a fresh, clarified effect after each wash. Pair with the brand’s Density Thickening Conditioner for fuller-looking and stronger-feeling lengths.
