For me i dont find it hurt all that much. They say the first wax is the worst, but every wax after that gets less painful.
I got it all taken off.
I dont get anything else waxed, although i plan on getting my eyebrows waxed every 6w again.
I cant say you can prepare for the pain.
First time experience was a bit nervous, and a bit shy and i was scared about the pain, but it really wasnt all that bad. The lady that waxed me was very impressed with my pain tolerance. I did have to grit my teeth to start off with but after a few strips I was ok with the pain and fully relaxed.
