Otaku Hair Studio is a Korean-run salon in Osaka that does Korean-style cuts, perms, and coloring. Consultations cover head shape, face shape, and hair texture, and only the needed service is performed, such as a layered cut, down perm, or straightening. Bookings are taken through Line or KakaoTalk, and after the appointment the stylist explains how to blow-dry and style the hair at home. The salon runs by reservation and requires booking at least one day in advance.
