How Long Should Your Hair Be To Brazilian Wax. Some places will rush you and do your brazilian wax in 15 minutes or less. Hair needs to be at least ¼ inch long for effective waxing, and up to ½ inch long, or about the length of a grain of rice.
If it's shorter (or if you got waxed in the last six weeks), you should wait a bit. According to jess and flo, many shavers come in and their hair isn’t long enough. After a few sessions, it will only take around 30 minutes or less.
If you’re a shaver, you should wait at least 3 weeks after using your razor or else the hair will be too short.
Your brazilian wax should last between 2 to 3 weeks before you see any hair growth. Unfortunately, we will not be able to perform a full monty wax/brazilian on you if you are 5 months pregnant or more and have not ever received a brazilian wax, or have not been waxed for over a year. As you start your wax regime, you might need to wait for the hair to grow beyond 1/4, but this will probably change if you stick to regular wax treatments. This ensures that the wax can grab onto the hair and pull out the entire hair follicle.
