Laser hair removal does work but it is pretty painful.
I suffer from polycystic ovaries and one of the symptoms is excess hair. It really knocks your self confidence. At one time even typing this would have me in torrents of tears.
I found this link which will answer all her questions:

After the first treatment I saw a noticeable improvement. I still go back every couple of months but my neck and upper lip were pretty dense with hair.
Electrolysis works but it takes years and years. None of the creams, waxing etc work - they just remove the hair until it grows back in, it might grow in slightly softer but it still comes back.
I hope she does at least try this treatment. It will hurt the first couple of times but after a while she won't even notice it.
Best wishes.
