I want to get rid of my mono-brow, my Moustache (i'm a girl), bikini line, my back hair and my chest hair,

with the mono-brow, bikini line, back hair and chest hair get these all waxed. Or if your too embarrased theres creams and strips you can buy in tescos and normal shops like that.
with the moustache i think laser treatment would be best, because thats the worst place to have hair and you dont want it to keep coming back. Its quite expensive but if you really hate the hair then go for it!
hpe i helped.
