I absolutely love this colour - when you first put it on it looks gorgeous and is a very strong aquamarine colour. As it fades, it turns more and more green until you are left with virtually blonde hair. This takes about two weeks if you wash your hair every day as I do which is quicker than most other colour of dye. However, I did find that using baby shampoo made it stay in slightly longer than the 'colour fast' shampoo I had been using (which was actually rubbish!). Due to the fast fade on this colour, I have only given it 4 stars as in all other respects it is a beautiful colour and I wouldn't mind going back to it at some point. -Squeaky-
