Well the truth is this. There were (and still are) so many hair shops within ten minutes of walking from my apartment and that so few people in my neighborhood spoke any English that I simply hadn't built up enough courage to just pick one and go for it until after a year and a half.
I love these hats. I just haven't seen any around that are big enough for my head.
Actually, I wanted to go all gray, but I knew nothing about the process. In Korean, the dear shop workers tried to explain to me that it required two steps (bleaching, then coloring), the costs, and how long it would last. I called my boss to help translate. She did. I changed my mind. "Just do it black," I said. They understood that.
