Iroiro is a 100% vegan and cruelty-free semi-permanent hair colour. Most vibrant and long-lasting natural colours. VEGAN-FRIENDLY, NATURAL, GENTLE, EASY TO APPLY. As well as colouring your hair, Iroiro provides your hair with the nourishment it needs to stay healthy – which is especially important when it comes to colouring your hair – thanks to the natural organic coconut oil in the ingredients, which helps to keep your hair moisturized throughout the colouring process. Many vegan products still contain harsh chemicals that can damage your hair. We don’t think that’s right. Here’s a list of harsh chemicals we don’t use in our products: Petrol-based chemicals PEGs Paraben Synthetic preservatives such as Methylisothiazolinone or Methylchloroisothiazolinone Synthetic fragrances Peroxide Ammonia PPD Alcohol Your hair doesn't need unnatural ingredients to look great – and we’ll never include them in our products.
