I don't have any advice. What I can tell you is that in 2011 alone, at-home coloring in the US reached 1.9 billion dollars.
There are special shampoos and conditioners. Won't be hard to find them in the store because hair coloring products are a 1.9 billion dollar business in the U.S.!
I love to color my hair. I recently colored it purple. How interesting! Did you do it yourself or did you go to a professional? I did it myself at home. Do you have any advice on how to maintain it?
At home coloring in the United States reached $1.9 billion in 2011 and is expected to raise to $2.2 billion by 2016.
