Hay Jess! We seem to keep bumping into each other lol!

(I promise I'm not stalking you lol
♥︎*Hugs*♥︎ ).
Disclaimer - I'm only just starting out on this journey myself so what I say is based on what I've read rather than personal experience, but from what I gather HRT will halt male-pattern baldness, and some people say it even causes some hair to grow back again, although I'm not sure how accurate that is. I've also seen a lot of talk about DHT reduction (DHT causes hair loss I think or something..?

), but I don't fully understand the ins and outs of that so one of the others will have to fill you in there

What you can do further down the line though is get hair transplants into the balding areas, which can also feminise the general shape of the hair line too (bring it forward and give it more of a feminine curve rather than the masculine "M" shape). You can also get a scalp advance as part of
FFS which will likely help with this too.
Of course, you'll probably need wigs while your hair grows out in any case. Wigs can be really fun though and gives you a chance to quickly play with different hairstyles to find what fits you best, so it's not necessarily a bad thing

Anyway, hope I've helped hun!
