Review (5/5): WET YOUR HAIR FIRST
at first i thought it didn't work, then i read the instructions. whops. you have to wet your hair fist. We got this for our 4 year old to have mermaid hair for her birthday, she hair is light brown, the color lightly showed, but was not bright like the picture- that being said it washed out easily (we've had problems in the past with other brands)
