Yes, in 2011 it reached $1.9 billion in the US and estimates has it at $2.2 billion for 2016.
It's big business. In America alone hair dye is a 2.2 billion dollar business.
My younger daughter hair once had blue hair! She loved it! Sounds interesting, does she partake a lot in hair coloring or the practice of changing her hair color? No, it costs a lot and she's always changing her mind you know. I don't really get the purpose for it either. Some of the main reasons for it would be covering gray or white hair, be fashionable or even to restore hair due to hairdressing discoloring or sun bleaching. My daughter did it just for the fun of it! lol I dye mine to color the grey for sure! Cool, hair coloring is quite popular. A study from University of Copenhagen found that 18% men and 75% women have used hair dye. That's really interesting, hair coloring sales must be great!
