Grandma here has a very old fashioned traditional Thai hairstyle. This is actually the first time I've seen it not in old photographs. Most of the hair is shaved in the back and sides, while the top is left short with two wisps in front of the ears. This was a common hairstyle for women before the Victorian era, when the King at the time decided that Western-style long hair (and shirts for that matter) were more acceptable for women. I hope this woman is not that old!
