I have had laser treatment done on my whole face. I have had about 8 treatments. My hair is a lot finer now, but I still get re-growth 
I recommend to you girls to only get laser done, if you have fair skin and thick coarse dark hair. It works really well on underarms, and bikini line.
I shaved in between all treatments, and a month before my first treatment. It didnt looked like I shaved. I was worried about shaving, because I didnt want to look like a man! But thats the only hair removal you can do in between treatments.
I used to bleach my face, and thread my upper lip before my laser. The areas I bleached, were very thick and blonde. I do not recommend bleaching if you have very fine hairs. I think its best to leave them.
I am now thinking of electrolysis. Has anyone done electrolysis? I have read reviews, that this is the only permanent hair removal.
