Can't say that I've ever done this, no.

Perhaps I'm just "weird" and haven't caught onto the chameleon syndrome yet.    But when and if I ever cut my hair, I do it for myself and no one else, regardless of what's going on in my life.

Of course, I can understand the desire that many women have to look as great as possible after a breakup, because of the message it conveys to the world. They want to be perceived as strong, daring, sexy and show the world that they still have a lot to offer and that they're not the least bit devastated by the breakup.
    You must admit that letting your appearance go immediately following may have folks thinking that you're taking it pretty hard.

Most of the folks here know that I am divorced and also broke up with my last boyfriend 4 months ago. And neither event had any effect on my hair. My commitment to growing it long and healthy remained the same as it ever had, as it does to this day. I like to think of it as one of the few steady and constant things that I have in this life.
