HOW TO CHOOSE THE RIGHT SHADE 
Shade 6.66 is best for anyone with natural hair between blonde and dark brown. If you would like to remain in the light brown range but want to explore other reflects and tones, check out 6.0 Light Brown. Hair Dye can only lighten your natural hair colour 1 to 2 levels – use our colour match tool to help you decide is this is the best shade for you. If you have long or thick hair, use two Olia red hair dye boxes. If you prefer a brighter colour that still reflects naturally, try the Nutrisse shade 6.60 Fiery Red
