Congrats on your first step. Everything you say is exactly what I went through, however I didn't start losing hair till 28 or 29. But at 34 it bothered me so much I pulled the trigger on a ht. I researched for years and I can say absolutely, 100% this was one of the best decisions I've made.
For me telling my gf and parents was easy, however they didnt understand why I wanted to go thru with a ht. none of them cared how my hair looked. But we all have hang ups and to get my hair back and move on from thinking about it all the time really is a great thing for me. And it might be a great thing for you. But many people around you may not fully understand.
Send an email to jotronic of h&w or mattj from rahal. They will certainly point you in the right direction. Good luck with your decision.
