I recommend keep growing your hair.
My hair is a few inches below my shoulders. I just started taking collagen about 3 months ago and it had made a huge difference in my nails, skin and hair. I wish I took it years ago. I buy it in bulk on Amazon Prime. My hair grows faster and looks nicer. My nails were fragile and are now strong. My skin is so much better.
When I was growing my hair out and before coming out at work I would sweep the hair behind my ears. Then about a Month before coming out I let it come own on the sides. I had a bunch of comments and would respond I like my hair this way. (I too got the are you going for a sex change comment too and I would say yes and smile. The other person would smile back thinking I was joking). One guy would corner me and ask what is up. He did it at meetings and in the cafeteria in line and in the hallway. He is the Assistant Director in Security. I told him the President of the hospital and my EVP and the EVP of HR are fine with me wearing my hair this way, what is the issue?
About a week later I called his boss and asked for his help as I needed a new ID with a different name on it. He was super supportive as well as his assistant director.
I had hair transplants twice. I may go back a third time but I do not know if I need them. Anyhow, I love my hair, the thickness, the color (blond, I have since colored my hair and it looks different than in my avatar) and how it feels on my head. It really is something that says feminine. It makes my face.
At some point you will need to confront the dragons under the table. I choose to do it in steps. Growing my hair, I took a huge amount of daily crap for years at home. My Ex no longer lives here and my daughter never says anything about my hair. She comments my lipstick is to bright (she never wears makeup, does not have pierced ears and wears a T shirt and jeans). When I visit my ex she never has a comment about how I look.
So, if you grow your hair will you color it? If so, what color? How long do you want it?
