A little more than $4 U.S (150฿) in a local salon in Chiang Mai. Shampoo, 15 minute scalp massage, cut, shampoo again and then style. The pros at the salon are meticulous and it takes close to an hour. Haven't found a place quite as good in Chiang Rai and it's a little more expensive at $5.70 (200฿). A traditional Barber cut can be had for as little as 50฿, but many of the hip barber shops charge 150-250฿.
