I actually sent my mother to BBB on her birthday a few years ago. She was a very good sport, but yes, all three hair styles they offer are horrendous, involve very tightly drawn hair and sometimes extensions. The tiara was included but are very cheap (and I had already gotten my mother a nicer one.) I don't know that my daughters will be going when they are even old enough. (They barely have hair at this stage.) I am hopeful that Disney does some upgrading on that particular attraction.
When I was a kid, my Mom got my Dad a haircut and a shave at the barber shop on Main Street USA, and we were all entertained by the Barber Shop Quartet. Better bang for the buck that was.
ETA - They offered three looks: The Princess, the Pop Diva and the Ballerina. All of them had the same basic look to your hair; pulled back tightly in a bun, slathered down with product. The Ballerina did not seem to use as much glitter. Princess came with tiara and some curly extensions. Pop Diva came with multi-colored extensions (a la Hannah Montana). They do makeup and nails as well. At the end, a fairy godmother dusts you with even more glitter. (Fairy Godmother "dusted" my Dad, too, as he was there with my Mom the whole time.) It was an absurd amount of glitter, but it was the experience I was paying for. The next day, after a shower, my mother was remarkably glitter-free. I think the whole deal cost about $60 and took an hour.
