In addition to being plastic-free and better for the environment, the Aveda Limited Edition Shampure Nurturing Shampoo Bar (£14) is also silicone-free, sulphate-free, cruelty-free, and vegan. And the thing is? It is all that and leaves your hair feeling soft and clean. The best part, however, is that throughout Earth Month (so the entire month of April), Aveda will donate $5 from the sale of each Shampoo Bar to nonprofit partner Charity: Water, an organisation that aims to provide clean water to people around the world in need.
