Okinawa sits at #01-02 Anchorvale Fields, 351 Anchorvale Road, in Sengkang, and holds a 3.6 Google rating from 104 reviews; the directory files it under tattoo, yet every review on record describes a hair salon — patient, skillful stylists, a queue system, and complaints about early closures and cash-only payment. Good haircutting is mostly good communication. Regulars bring a reference photo, name the centimetres they can lose rather than asking for "a bit off", and check the back in the mirror before the cape comes off. A fringe shows unevenness at once and grows out fast, so it rewards a stylist with a conservative hand. Neighbourhood salons run on walk-ins and queue slips, so weekday mornings are calmer than weekend afternoons. However the tattoo tag got there, this Anchorvale Road unit is plainly where Sengkang goes for its hair cut — arrive early, carry cash, and say exactly what you want.
