the fact that your hair fell out faster when you dropped the dosage down makes it more likely that niether the exemestane nor the testosterone is really the primary issue. as mentioned previously your finasteride dosage is LUDICROUS and the cause of your rapid and massive shedding is most likely due to prolactin, which is probably due to high dose finasteride (suppressing dopamine as well as the modulating effects of DHT on the ER) combined with the HCG.
it has been made very clear, more than once, that you are taking way too much finasteride. yet you continued, and even increased it further. not really sure what would possess you to do that.
did you even try the nizoral shampoo?
