With my straight hair, I used to cut it as simple as possible: short with the machine. Back home, I did not even bother going to the hairdresser, I did it myself!
I got a few nice experiences in the last months: Sarah cut my hair on the roofs of Ulan Bataar. The hair dresser in Bangkok has one dressing box per customer in a mall close to the metro. The barber in Varanasi made his services directly on the street. I enjoyed a hair massage after the cut in a salon in my last hour in Nepal. So did I in Kandy, Sri Lanka on the 1st of January, in the same house than the hotel!
