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 buil 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.
