I had a very similar experience as Cindy my first time in. "I am trans, I want a more feminine look. I need all the help you can give."
Beauty technicians, hair stylists, manicurists, waxers... etc. are like therapists, it is harder to get what you want from them if you don't just tell them. They booked an appointment with you after all, so chances are they want to get your continued visits as well.
You can always ask around or check yelp for the best reviews. I have a thing about communication, especially when I get my hair done, I am real specific and nuanced about certain things. I love it when I find someone who can get what I mean and still be creative in their own way on top of that.
