It's possible to save a bit of money if one considers going outside TST and Central. I live in Mei Foo and Chinese friends recommended a place close to my apartment. Today I got a haircut from stylist Sam Man of Promised Land in Mei Foo, No. 29C3-C4 Humbert Street, Mei Foo Sun Chuen, Kowloon, 2307 4610. He's not fluent in English, but he communicated fine with me. He really listened hard and gave me exactly the haircut I wanted, plus suggested improvements, and he was right. A nice long shampoo by his assistant, pretty good scalp massage, a precise cut, blow-dry, more cutting, hair was totally soaked again, then a final blow dry. My hair is extremely fine, and he knew just how to handle it. It costs just under $200. This is not a fancy place, but I see lots of Hong Kongers with great haircuts on the MTR, and they go to places like these.
