How do you prepare for a bikini wax at a salon?

i am a beauty therapist!!! you don't need to do anything as all will be done at the salon. the therapist will pre-cleanse the area, then apply some talcum powder (in case your nervous, it can cause sweating!). Most salons will provide you with disposable underwear but wear old undies just in case...... some of my clients say its helpful to take a few painkillers before going as this helps with the pain!!!! hope this helps.... good luck!!!
