Waxing is a great alternative to shaving as it greatly helps reduce irritations associated with shaving, including ingrown hairs. However if you're prone to ingrown hairs or have sensitive skin, I always recommend having a regular skincare routine for prevention and treatment. It's basically like having a facial regimen for your vagina.
I suggest daily:
Clean: mild soap, ideally no non-natural fragrance./
Exfoliate, Exfoliate, Exfoliate: I cannot stress this one enough. It's as simple as firmly scrubbing with a wash cloth or luffa. For more persistent cases, try a sugar scrub 1-2x per week. I use just plain white sugar, but you can make your own by mixing in a few drops of oil if you like/.
Tone: I use alcohol free witch hazel. Apply after you shower and post-exercise if you don't have time for a shower right afterward./
Moisturize: I love oils, like grapeseed and coconut but if you prefer lotion avoid ones with added perfumes and dyes./
Spot treat: Tea tree oil is a great remedy for those pesky bumps and in-growns that are a bit more persistent. I suggest applying 1-2x a day until resolved.
Most importantly, DO NOT PICK! This is a difficult one and I get it, but you have to remember that picking typically makes it worse and can even lead to infection when bacteria from your hands or tools get into your blood stream. If you absolutely can't resist or you feel like the hair just needs some gentle coaxing, I suggest showering first to clean the area, hands and help open pores. Use a clean pair of tweezers or lance to help remove hair, and apply witch hazel or tea tree oil once your done.
As with any routine, CONSISTNECY IS THE KEY TO SUCESS.
