Welcome and thanks for posting your query on HCM.
As per your query you have alopecia universalis
since you were 9 years old. I m really empathetic to your problem.
Now the treatment part is bit difficult as the time elapses it becomes practically difficult to treat it. Neither it can be cured by blood transfusions and nor can be caused by the same.
The reason for above is the body of the suffering person secrets the antibodies
form the bone marrow
. SO we can not change the bone marrow. So also is true that blood transfusion can carry the antibodies but these are not effective in the receiving person.So it can not cause this type of illness in other person.
The very last thing to know is that hair per say are not very important for body and are of cosmetic importance only. SO there is no long term issue except for cosmetic appearance of a person.
Hope these informations are helpful. If you have any furhtr query I will be happy to help.
Wish you good health,
