It's funny, I leave my hair down to be able to "hide" easier, and it goes up again if I'm feeling more comfortable. I almost always leave my hair up in my day-to-day life because , though I like my long hair, it's a pain in the butt. In therapy, it's just easier to hide with it down. I am not sure T had noticed (I've only put my hair up maybe twice in session, and that was just in the last 2 weeks). I never thought leaving my hair up in a ponytail would present as "less adult". You'll have to keep us updated on your experiement.
