The Aesop Volumising Shampoo comes in a 500ml pump bottle & has been designed to give a lift to limp hair. The volumising shampoo will deal with hair that looks & feels lifeless. The formula has been specially designed to be lightweight & contains polyquarternium cellulose polymers, an ingredient that forms a coating on the hair close to the roots & then expands. This helps to separate out the hair shafts & creates that lift that you are looking for. The Aesop volumising shampoo is best used in conjunction with other products from the Aesop hair care range.
