You might also need to use a body scrubber to help stop your skin from developing ingrown hairs. If you gently exfoliate with a pouf or some body scrub with oats or another gentle kind of abrasive material in it, before you shave, that can help.
Then scrub the same area for several days afterward as well. If you get rid of the loose skin cells it stops them getting trapped in the hair follicles. It can also help the newly growing hairs to break the skin so they don't start growing down and irritate your pores.
I really hate getting ingrown hairs, so I am sharing my best tips to help you get rid of yours!
