I'm so sorry your mom is at odds with you, and I would feel the same way if someone made me do something to my body that felt invalidating.
Idea for the future/creative compromise: you could wear stockings.
If you are living under your parents' roof, and especially if you are under 18, some of these things are going to be tough. Even as an adult, there was a time when I had to move back in with my dad after I had an injury, and there were simply some things I had to deal with because his rules/his house (that was before I realized I was trans

). The flip side is, it can motivate you to plan your future situation and figure out how to become more independent. It can motivate you to be successful. Anger and frustration CAN be temporarily useful, if you channel them into creating positive, productive changes for yourself.
If you're still in school, focus all of your frustration into being the best you can be, so when the time comes to leave, you have as many options for success available to you as possible. I haven't come out at my job yet, but I made a point of kicking my performance up to the next level once I realized I had to transition, because I NEED my job and want to keep it. I got a surprise raise without asking.
The good news is it's hair and it will grow back... pretty quickly. My guess is your mom really has no concept of how hurt and rejected that can make you feel, because she doesn't understand what it's like to have those trans feelings of conflict. She's probably scared for your well-being, too. I'm sure every parent wants their kids to grow up "normal," and never be bullied, never have to deal with any risks (being trans comes with a lot of social adversity), etc.
My dad means well, but still says things sometimes that make me get so angry I never want to see him again. Then I remember that it's coming from a place of love (no matter how ridiculous or hurtful it comes across), and that's enough for me to remember to calm down.
My advice would be to think about the long-term picture and choose your battles wisely. What are your goals? What kind of relationship do you want to have with your parents? Are they paying for your education?
Can you open up communication with your parents? Are they completely closed off? Might they come around with time?
Is therapy an option for you?
It hurts more than anything some days, and it's okay to feel that way. Do what you need to do to let it all out, and then dust yourself off, and work at being the best version of yourself you can possibly be. That's something no one can take away from you.
And also, depending on the family, sometimes weddings are a *HUGE* deal. I work with a lot of brides and bridal parties in my profession. My family doesn't have that culture, but if this was one of those "big deal" weddings, I wouldn't take this incident as personally. I have seen grown women get into raging fights over types of shoes and nail polish colors. People just get nuts about wedding sometimes and if this was a one-off situation, I'd chalk it up to wedding madness.
