GHD Purifying Shampoo is a rich, deep-cleansing, clarifying shampoo with UVA protection for all hair types. Designed to be used prior to your regular ghd shampoo to gently remove product buildup, oils, and pollutants. Formulated with a polymer that removes hard-water minerals, heavy-metal salts, and excess oil, as well as chlorine (to help prevent discoloration of hair after swimming). GHD Purifying Shampoo contains positively-charged conditioning polymers that reduce static and make it easier to comb the hair when wet or dry.
