Does Laser Hair Removal get rid of shadow for trans women? If so, how often on average do you need it done?

I am a post operative trans woman, which means I do not produce testosterone anymore. I don't have fast regrowth but enough for a shadow. I know electrolysis is the permanent one, but it laser works for a long time *and* gets rid of shadow for a long time I feel its worth getting it done semi-periodically. If laser does not get rid of shadow it's not worth it. Shaving isn't a problem, it's the shadow left. This is so important to me but there are so many different kinds of treatments with different claims, and it's hard to research online because distinctions between electro and laser are not often made. Price ranges are all over the place. Is laser like lip injections, where you get it once every 8 months or so? I just really need to get rid of the lip shadow, that's all. Thank you in advance!
