Like cutting bangs, dying your hair is a real time commitment. I personally think that people color their hair because it represents their personality. Also, some people get bored and need a change, and hair color is the easiest thing for them to change. It’s a valid reason to make a change, and seems like a good idea to me. So, in summary, it is said that people dye their hair because they are somewhat desperate for a radical change and the color might fully display their personality!
