The Harmony Barber Shop does not take reservations. This is a first-come, first-served experience.
Girls are welcome to have haircuts here. Many of the Moms Panelists have taken their daughters to the Harmony for a trim. My understanding is that the Barber Shop will no longer put a girl's
hair up in a bun, because that's now the domain of the Bibbidi Bobbidi
Boutique, but they will give her a great haircut (something the BBB
won't do) and apply glitter gel to finish the look.
It is not possible for you to directly contact the Barber Shop. However, if you have specific questions, you may be able to get the information you need via the Guest Communications Office.
They can be reach through the mail at:
