I think your hair looks great Jennifer....
And if it makes you feel better I am that (semi) bilingual sister, and I've heard them discuss these kinds of situations and the women they are talking about are always offended and angry when really they aren't saying anything all that bad at all. Whatever they are saying is never as bad as people assume it is. You don't understand, so you assume the worst, which is understandable, but it's not like they're saying you smell or anything.
I also don't think it's unprofessional of them to talk about what they're doing in their native tongue...it is, after all, the language they know and speak best...she could have been saying anything. It wasn't necessarily bad. But for her to say it (and have people respond to her) in the her native language - well I just disagree with the posters that call that "unprofessional"....
But that's neither here nor there....I think your hair looks wonderful.
