It's definitely worth having your eyebrows threaded while you're there - I was really pleased with mine and it was a good 8 weeks before the re-growth started.
However, don't be talked into having any other facial hair threaded away... I came out of (the hairdresers opposite Romeo & Juliet - Sebastains? not sure of name) looking like a plucked chicken and I really don't know what I can compare the pain of facial threading to....

uuuugh, makes my eyes water just thinking about it! A process I shall definitely not be talked into again!! But I wonder if it's as painful on the legs....?? Anyone know?
I'll be sticking to eyebrows only from now on!
They do a great manicure and pedicure there too, and it's so much cheaper than having it done here!
