  • Always complete a skin allergy test 48 hours before you colour your hair to help reduce the risk of an allergic reaction. For further information go to www.garnier.co.uk/becoloursafe
  • Before rinsing we recommend you dry-massage your hair to release the oils, add a little water, massage again and rinse until the water runs clear.
  • When you rinse the hair, the colour will act as a shampoo. Use the conditioner after rinsing and once the water runs clear.
  • If you've got grey hair try to avoid colours with more intense reflects (e.g. reds) as they tend to deliver less grey coverage than other shades.

  • Nina

    As I'm new to colouring my hair I was quite nervous, but the colour's fabulous and really natural.

  • Parvinda

    It's definitely more shiny, everybody is saying it's more shiny.

  • Maria

    I really like the colour. It's just amazing and it's never felt this good.

  • Manuela

    Olia was a completely different ball game. It doesn't drip, it smells really nice and I’ve got a shimmer in my hair which I haven't had before.

  • Sandra

    This one was particularly creamy, and so there was that thickness which was quite luscious.
