Electrolysis. Have you had it? Does it work? etc?

I have phoned a local beauty salon to ask about having laser hair removal, but apparently electrolysis is better they have told me? I am a woman and have a really annoying problem with unwanted hair on my stomach kinda like what men get that trail thing. It is driving me mad to the point I am plucking so much and attacking the area that it is sore and scabby, it's really affecting my confidence. I have been told it costs £9 for 15minutes treatment. I am going for a proper consultation at 5.30 today, then going to book in once the skin has healed up etc. Have you ever had electrolysis or know anyone that has had it before? How does it work? Is it permanent? Does it hurt?
