Meh, I have been coloring my hair for the better part of 15 years, since i was like 13 or so, never had an issue with it, I do it because I like it. Also have a ton of ink done, so attention is something I am bound to get. Dont feel its my job to change how I like to look because it makes someone else feel uncomphy. It wasnt the talking about the colors that pissed me off, it was the fact that he told me only black people have dreads and white people shouldnt want them because they are dirty. Being as how I have grown up in bigger cities and and ghettos, so most of my friends are black, and are not dirty. And alot of them have dreads.
I understand where you are comming from, but why change how you like to be to avoid ignorance from other people?
