Welcome to part 4/5 of a 5-part series on the ongoing evolution of specific segments of the pro salon industry. This week, I share observations on both the history (the abridged version for some context) and current state of both segments; and ask what I hope are thought-provoking questions related to the future of each. Past episodes in the series (#'s 6, 8 & 10) offer my take on the state of the media, events & online learning categories- and where each might be headed in the future.
