A small percentage of women who brazilian wax for the first time may break out with tiny whitehead bumps along the bikini area. This is known as folliculitis and can be a source of irritation and aggrevation. Folliculitis occurs in about 1% of first time brazilian/bikini waxers and is easily treated.
After waxing, the hair follicle is open for about 24-48 hours and is suseptible to anything that may cause infection, even your own skins bacteria.
Folliculitis lasts 1 to 2 days if using PFB (a product that helps prevent rash/waxing bumps & ingrown hairs). On its own, folliculitis clears up in 5 to 6 days.
