Beard Hair with some ginger hairs.

Hello, I am amale who is looking to have laser hair removal/reduction on my beardand mostache. I have pale skin and thought that my hair was prettybrown but when I went to the clinic the lady looked at it and saidthere were some orange and a few white hairs mixed in with the brown which would mean that it may not work well.When I just have stubble its quite difficult to notice the orange andwhite hairs but when I grew my beard a bit they started to becomemore noticable. What I am hoping is that it will reduce thevisibility of my stubble and make it much easier to shave. Also Ihave heard that if I have lots of sessions (at least 8) then I may beable to get rid of some of the orange hairs too. The thing Iam worried about is if I get rid of the brown hairs the orange andfew white hairs are still visible, even when it is just stubble thatshows after shaving and it will look weird and patchy. Or will itonly start to look odd if I leave shaving for too long? Also what type of laserwould you suggest would be best for this sort of thing, Thanksfor your help
