I didn't get my hair done, but their nail services were extremely expensive. I didn't get a manicure, just a polish change (take off the old, put on new) and it was $25! (I can get that same service for less than $10 at home).
I found them to be overpriced, but I guess it all depends on what you pay for those type of services at home. I don't think that the skill involved for the polish change was any better done there than at my own salon. YMMV.
