I had it at Salon for several months ago, costed me HK$400. I finally got it at a beauty shop mainly selling hair care products which located at 1/F, Phase II,Metropolitan Centre, Tseung Kwan O charged me HK$190. I had the treatment by myself. It is quite easy and convenient, the result is quite good. If you need the info of the shop i can pm to you tmr.
