I am having a PRP treatment done Monday.  $800.00 and 1 hour. I watched all the videos and did a lot of reading. 
When I spoke to the Nurse she asked did I know if I had high T. I said I am pretty sure my T is low 

 She said she had the procedure done and it was great. The Doctor explained my hair fell out due to a hormonal sensitivity to T and that it would need to be repeated every 6 months due to the new hair will be sensitive to T. I can not wait !!!! 
I am a bit apprehensive about when I tell them I am trans, my t is 25 ng/dl, I am on oral estradiol and finasteride and want a feminine hairline. I will definitely let all know how well it works. 
Best of all it is 3 miles from my house!
