Well, after my last haircut fiasco (see "Haircut backfired on me!" thread), I went yesterday and got my hair all chopped off! Went back to my classic bob. Even though I tried someone new and I don;t think she did a great job, I do look so much better.
I would love to have long, luxurious hair but the truth is, it never really looks great (like in the magazines) and it really drags my hair down. I just feel sexier with a more short, blunt cut.
So I say, you do what looks good for your face and you hair type, and as long as it looks healthy and it is a good cut, then it is the way to go for you.
