I know this isn't for "regular" hair salon visits, but for her very first haircut (or anytime you want it to be fun/special) there is a Barber Shop in the Magic Kingdom that does both girls and boys... we took our 3 yr old girl there for her very first cut and do....it was amazing. She sat way up high in an elevated salon chair and was given toys to play with and stickers all over her of Mickey. They cut her hair, then put it up in a cute pony with all sorts of glitter and pixie dust! And...the best part is that all cuts at the shop are $7.50 (plus tip of course)...yes, $7.50!!! She also saved her hair in some tissue and sealed it with a Disney sticker AND she got a set of Mickey ears that has embroiderd on the back "My First Haircut". All of this is INCLUDED for the $7.50. If it is not her 1st haircut (boy or girl) then you just don't take the Mickey ears. I thought it was amazing and she had a blast. We wil keep her hair trimmed locally now, probably at my salon by my hairdresser, but whenever we go back to Disney we will most definately go there again and again! Friends tell me the same thing!
Best wishes for a happy first cut! Take lots of pictures!
