The Tresemme Naturals line offers a lower sulphate cleansing alternative to the rest of the Tresemme line. Many shampoos contain sulphates, which is the one ingredient that causes the foaming when you wash your hair. There have been many debates on whether sulphates are good or bad for your hair, but the general idea is that sulphates is not harmful to you, but for some people it may cause dry scalps. This shampoo also contains certified organic aloe vera and avocado extracts that moisturises your hair and protects it against damage and breakage. The formula also contains no dyes, is hypoallergenic and safe for coloured treated hair.
