I used a lot of Hello bubble to dye my hair. it is not really same the colour in the product depends on what colour in your hair. However, I still love it and will repurchase it. I rise the hello bubble with warm water until it clear all the colour after 2 days I wash my hair again it doesn't leave any colour left than other products from different brands I bought in Australia. The product has a hair mask it leave my hair soft and smooth. Really high recommend it.
