[SEP] I urge anyone thinking of using this product to check the Splat site for full information. I had admired someone's hair and she recommended it, telling me the color lasts about 3 weeks. I purchased the lavender color yesterday and did my whole head. Since my hair is frosted, I did not use the pre-bleach, just the color. The color came out a hideous red/purple and it stained spots of my scalp. even though I did not rub it in. I have washed my hair 6 times, hoping it would fade but the color got worse and the stains on my scalp remain. I went on the Splat Site and now learned that the color lasts at least 6 weeks and may leave a permanent color which I can only remove by bleaching all my hair. This is not written on the packaging and I would not have bought it if I had known. (I've had colored streaks applied at a beauty parlor - they looked great and faded after 3 weeks.)
