Best Answer: Yes I've dyed my entire hair each color. Green and pink is hard to keep up with. They bleed quick. Green faces quicker if its lighter. I did go for two years with pink hair but sometimes pink does fade into a very beautiful light pink. Purple and blue were fun to. Couldn't get the blue as light as I wanted but the purple one was amazing. Had that one on for 3 years. And if you do all 4 colors at once you can get a very pretty effect of Mermaid hair or if your going for a more galaxy kinda look.
