Unfortunately, hair medication is largely a YMMW thing. Some people might have amazing results with it; some might have poor results. Most hair doctors recommend waiting at least one year after you have gotten on finasteride, spiro, and estrogen to see how they have affected your hair before moving on to the hair transplant option.
Also, there is hairline lowering surgery, which moves down your hairline instantly which means you don t have to wait a year for the transplanted hair to grow out again (the transplanted hair grafts tend to shed after being relocated due to shock). Most hairline lowering doctors prefer that you have full hair at the frontal line, however, so most males with MPB are not eligible because their hair is thinning as well. Females usually tend to qualify because they are not experiencing MPB. But, if you have thick frontal hair after a while on HRT, you can look into hairline lowering surgery as another option.
And... for the record, I would like to state that Avodart (dutasteride) also inhibit Type I in addition to Type II, and Type I is present in the brain tissue. Long-term research has not been done yet on how inibiting Type I enzymes in the brain tissue will affect humans in the long-term.
Currently, there are no human studies because no one have been born with a Type I enyzme defiency. There are already people who have been born with a Type II enzyme deficiency, which is why finasteride was cleared for long term hair loss with the information gleaned from those subjects' health. That is why most hair doctors are uncomfortable recommending dutasteride as the first mode of attack - they usually will prefer you try out finasteride first to see how you react to it before moving on to dutasteride, because - basically, you are gambling with your brain tissue and how it will be affected in the future, especially once you get to elderly age.
Dutasteride was intended for bengin prostatic hyperlasia in natal males - a medical treatment that is not intended for hair loss and certainly not a lifetime regimen. They move on to other options including surgical removal if the prostate gland does not shrink in response to dutasteride.
I just wanted you to proceed with caution, armed with information about Avodart (dutasteride).
