Generally Facial hair is not reduced that much on HRT. Body hair yes, but facial hair not so much. It can reduce some for younger people, So it might reduce hair growth some.
HUM...Most doctors I'm aware of prescribe an estrodol (plant based) Bio identical estrogen. Permerin was used in the past all the time, but has fallen out of favor to the newer estrodol.. Permerin is effective, It will work, BUT it can and does effect clotting factors and liver function far far more so then other newer forms of estrogen. It's less of a problem when you are younger, but talk to your doctor. spiro is pretty standard btw and works well for MtF
Doses, etc can not be discussed here btw...
