I often do this treatment and end up with patches that remain wavy and need re-touching (no matter where I go, also here twice before with other hairdressers) but this time, this issue was really really minimal if not unnoticeable (only one strand at the inner part of my hair is not as smooth) So I hope and feel I can trust Takuya long-term to re-do this procedure and finally have a place and person to be secure with. A little longer head massage would make things perfect!
