I have accidental, unintentional ombre hair and I hate it! This is because I didn't color treat my hair during pregnancy. Before that, every time I colored it brown, it always turned auburn (I'm cursed!). I've colored my hair just one time since I had my daughter, and that was back in August of 2009, so my hair has obviously grown out a bit since then. My roots are a medium brown color and the rest is auburn-ish. My accidental ombre look isn't as pronounced as others since I didn't do this on purpose. Frankly, I was always embarrassed by it and I never would've thought it would be 'trendy'. I'm not trendy. Really, I'm not. I'm a jeans and hoodie type of gal, hence, why I love fall!
Now don't get me wrong, I'm not completely knocking ombre hair. I've seen it done where it looks really nice! Still, it just seems like something that's really easy to get bored with.
