Amplify hair's shine with the Pureology Smooth Gloss Shampoo, a sulphate-free formula that smooths the hair's surface to create glossy shine and protect colour vibrancy. The formula is powered by a trio of amino acids inspired by the protein structure of silk. This blend helps to reduce the appearance of frizz with up to 72-hour control. Cleansing hair without stripping, the shampoo's gentle lather releases an uplifting scent of bergamot and sandalwood with each hair wash.
