Would frequent this place when I was still an undergraduate. Hairstylists are pretty chatty and I feel comfortable around them. They would provide free locker and mineral water prior to the service, as well as standard magazines. Most of them are Malaysians, it seems that local hairdressers located in shopping malls are pretty rare?
They have a loyalty card program which IMO is not as good compared to the student discount where I could get a straight 15%~20% off. You will have to choose which discount to take up during payment, either having points converted into your card for future reductions or a straight 15% (or 20%) off your haircut. I always choose the latter.
