I had a gray beard and got laser to get as much as it could get, followed by electrolysis for the rest. I also had laser on my legs and to trim the pubic patch. I had laser on my chest and will have an occasional white hair grow but otherwise no. I probably could have waited for the chest to see how HRT would affect it, but I was shaving regularly because I couldn't stand to have the hair there.
I haven't had my arms done and don't intend to, especially now that the hair is so fair and light. I also had my armpits lasered, just so I wouldn't have to shave them. I don't have noticeable hair on my back.
At one point my electrolysis tech sent me back to the laser tech for some hair on my face. Laser is quicker and cheaper than electrolysis for the hairs it can handle.
