I have naturally very light blonde hair, and this color never washed out all the way. After it washed out about 75% of the way, it stopped coming out, and my hair remained a gross light-brownish-purple in ugly patches on my head for several months. I can't say this was the company's fault because I had been warned many times that this could happen to people with light blonde hair, but other brands I've used have washed out fully within a few weeks (e.g. manic panic). However, the color did look vibrant and pretty when I first dyed it, and if you don't have light hair, you probably have nothing to worry about.
