First of all, if you speak only English, this is not a place for you. There was just one person speaking English who wasn't my hair dresser.
Second, they just wash your hair before cutting it. I showed them a picture to cut my hair based on that but she just cut it and removed excess hair from me, nothing more.
Third, she didn't show me back of my head with a mirror. I could have asked, but they should do this automatically for satisfaction of customer.
Anyway, if I don't find someone English speaking, I might go there again, otherwise I gi to someone who can understand me and I be able to guide him/her to how cut my hair.
