I used a Tria Laser on most of my body hair pre-HRT and it hasn't grown back. After HRT, I don't need to shave those areas I couldn't hit with that like my back and back of my legs much, though a handful of hairs there still grow and will grow to full length, so I still shave them occasionally to prevent that.
Facial hair, I just had to go with electrolysis. Quite a lot of it was gray, and neither PM nor HRT had much effect on it.
