Waxing - The Procedure
How long does the hair need to be to get a Brazilian or regular bikini wax?
Hair needs to be 1/4-inch long (about two weeks of growth after shaving). This length is perfect because the wax can easily grab the hairs and pull them out. Trim a bit if you have long hair before coming in for the first time. Long hairs make the esthetician's job a little harder, and waxing more painful.
