Business Directory - specifically, hairdresser

My apologies if this information is somewhere and I'm just not finding it. I am looking for a hairdresser, and checked the business directory. There are two listed, one of which has 5 "thumbs up" but the directory doesn't seem to have (a) information on how these business got here (did they post it themselves, are they posted by an expat member, or some other way?); and (b) there doesn't seem to be a place for actual reviews (what did you like, what didn't you like, what did you have done?). So....do any ladies out there have more information than a thumbs up? I'm looking for color and cut. I went to a place that was recommended in Saigon about 3 weeks ago, and it's already faded and off-color
