Attention NYC ladies.. I Need Your Help!

Alright all you New York City ladies, I am attending a wedding in NYC in October and I need to make a hair appointment.  Where do we go?  In a city where its impossible to get dinner reservations I am assuming a blow out at 3pm on a Saturday may book up fast, so my friends and I are going to make appointments now.  The hard part is we have NO idea where to go.  We are staying in Midtown East so any recommendations you can give us would be very much appreciated.

Please suggest away.

Thanks.
