Drink plenty of water. Hair is removed easiest from hydrated skin.
Avoid caffeine for 2 hours prior. Caffeine is dehydrating which can make it more painful/difficult to remove hair.
Avoid alcohol for 2 hours prior. This may result in excessive bleeding. Some pinpoint bleeding is normal.
Make sure your hair is long enough to remove! If you are able to pinch and pull the unwanted hair it should be ready.
Come to your appointment in loose-fitting clothes if possible. Your skin will want to breathe after!

No tanning. Hair removal also removes a surface protective layer of the skin and you are more likely to burn.
Don’t apply any lotions or oils. You pores are open and applying product may result in irritation, bumps, etc.
Avoid sweating. Your workout can wait!
Avoid hot water such as a bath or hot tub.
Feel free to exfoliate after 24 hours with a chemical or physical exfoliant to prevent ingrown hairs.
