The guys I see have facial hair and arm hair. I have not viewed anywhere else.
If you take T then depending on time on the T your hair follicles will become active.
I do not know any way to stop the growth.
I have been on MTF hormones for 22 months. My torso hair is gone. My leg hair is very light, slow growing and sparse. My beard hair (being removed by electrolysis now and I had 3 laser sessions to) grows slow, but grows. I did not have much torso hair prior to HRT. My leg hair was there but light. So if you are on T and face hair grows I would think it will continue to grow. I do not know about arm hair, mine is thin and sparse.
Laser is a good way to get rid of dark hair. However, I have heard that if you are not on CHT hormones for 8 weeks (6 before GCS and 2 after) face hair can start to grow again. I do not know if this is true.
Perhaps posting in the FTM section may have better answers.
