Ouai Detox Shampoo We like to think of the Ouai Detox Shampoo (£24) as a two-in-one shampoo because you get the incredible cleansing benefits with the ultra enjoyable experience of the brand's Melrose Place fragrance. The formula's chelating agents purify and remove dirt from your hair whilst the apple cider vinegar works to sweep away excess oil.
