This is a wonderful topic. We should keep bumping this.
I have dealt with this all my life as well. My mom relaxed my hair at a very young age and it had always been healthy and long. I always got the "you have white girl hair" comment, but I just ignored it. It wasn't until I got to college (a black college) and had to deal with people saying I thought I was "all that" and "her hair is a wig"...that I decided to cut it off. My hair was past the middle of my back (past my bra) and I went and got a fierce bob cut up to my ears. It was cute, still relaxed, and wouldn't you know it...I STILL GOT THE SAME DAMN COMMENTS!!!
During my transition, no one believed that I was growing out my perm because my pressed hair looked just like the relaxed hair. I then received comments such as, "There is no way a black girl's pressed hair can straighten like that without chemicals..." Then...I was labled as being Dominican. I don't know where that came from.
I finally got all the relaxed ends cut off a few weeks ago and I went curly to work and every where else. I'm still being asked the same questions. If my hair is long and straight, it's white girl hair. If it's short and straight with bounce...it's still white girl hair. If it's natural...I'm mixed or Dominican. I've simply accepted the fact that some people are inquisitive and others are just plain ingnorant. No matter how much I try to alter my hair, I will continue to get same freakin' comments and questions. :-)
LOVE YOUR HAIR AND WHO YOU ARE LADIES!!! Some people will never accept that we as people are different.
