Rituals Pure Hammam Volume and Shine Shampoo. Volume and shine shampoo based on Organic Argan Oil and Organic Refreshing Eucalyptus. An innovative volume system opens up and plumps the hair scales, making the hair thicker and with visibly more volume as a result. Organic Argan Oil adds a rich shine to the hair. Refreshing Eucalyptus provides a sensational fragrance experience while revitalising the scalp. Pure Hammam protects the colour of your hair, is ideal for daily use, and makes blow drying easy.
