Garnier Olia is the first permanent home hair colour powered by oil, not ammonia. Formulated with an Oil Delivery System, the high oil content in both the colourant and the developer allows for the replacement of ammonia with an odourless agent. The floral fragrance recreates the home hair colour process, becoming a beauty treatment for the hair. The formula is enriched with four flower oils, camellia, sunflower, passionflower and limnanthes alba. ODS technology replaces the need for ammonia by using oil to propel colour deep into the hair fibre. This process allows colour to achieve rich, vibrant results while respecting the quality of the hair. Colour is rich, vibrant and full of body, ensuring a consistent colour result. The colour develops in 30 minutes and comes with a Silk and Shine Conditioner (54ml). Available in 21 shades.
