I've both dyed my hair and used wigs for years. Wigs are a million times easier and you are much more likely to get the exact color you want without damaging your hair. If you get something heat-resistant, you can re-style and re-use them for many years (if you are gentle and nice to them.) I recommend Arda wigs. (I'm actually wearing an Arda hairpiece right now because I felt like having blue bangs today. Tomorrow, my hair can be another color with little fuss!
