rsanders, Your experiance and situation mirrors mine to the tee.
I went to MHR when I was 26 to get my hairline back.
The doctor misinformed me, ok, he flat out lied, and I ended up regretting it.
The HT caused excellerated hairloss, and made my air look completely terrible. I went from thinning to bald in a matter of 10 months due to MHR.
You are fortunate to be asking questions now, and not have done the mistake I did. I went for another HT when I was 28 only to have picked another quack physician, putting money over the patient first.
Keep up hope, and don't give up. Start reading and learning. and you will find yourself in the right hands.
Feel free to PM me if you have any questions.
GOOD LUCK!!
