To celebrate the winter break.....and also to freak my parents out, I want to dye my hair! I was thinking a light, very vivid blue. However, I have never dyed my hair in my life before, and only know a little bit from Googling. My hair length is around 4 inches and dirty blonde. For the most part there are no curls. Any tips of dying hair are appreciated. Also, I am not set on the color blue yet, so if you have any good suggestions don't be shy.
