This awesome video is from my sibling. Notice the use of vinegar to rinse hair near the end of the video! Vinegar is actually good for your hair, and is used in the no-shampoo community as an alternative to conventional conditioner.
Also cool is the use of a straight razor! I’m surprised the barber had such an old razor, though. In Japan at least, the traditional razor, used before Westernization, is the kamisori. I figure Korea used something more similar to that than to European straight razors.
