Those annoying red bumps that crop up after you shave are likely a case of folliculitis, an inflammation of the hair follicle. Unlike many other-itises, this one has wonderfully straightforward solutions. Upgrade your hair-removal tool kit with:
A salicylic acid scrub (like Bioré Pore Unclogging Scrub): Use it on your bikini line two to three times a week (between shaves) to buff away the dead skin that can block hair follicles.
A moisturizing shaving cream: It will soften both your skin and your stubble to make shaving less irritating.
A clean, sharp, razor: Look for one with four blades (you'll get a close shave without pressing too hard), and toss it after a few uses (when it's dulling and may be harboring bacteria).
An antibacterial soap (like Dial): Wash your bikini line with it every day to kill the bacteria that can inflame hair follicles.
