About hair: I asked women who have hair that is like mine - thick, wavy, etc. - who they went to for a hairdresser. I went to that hairdresser still presenting male. I liked how she cut my hair and we established a friendship of sorts. When I started coming out I went to her and said: "Before you pick up anything sharp, I have something to tell you." I then came out to her. She changed my hairstyle from male to female and told me how to take care of it.
I don't know if that would work for you. I've always wanted to establish a relationship with a barber or hairdresser, so that they would learn what I liked and didn't. If you don't know the person, you might carry a picture, but look at the model's head and face shapes to see if they are similar to yours. I think it is better to just describe what you want - fullness here, length, how much effort you're willing to put into caring for it, etc.
I agree that hair is important, especially when you still have some male features and mannerisims.
Good luck, Maiara!
