Actually there are a couple different things she can do.
First off, the reason she gets those red bumbp is probably do to thick hair. My guess is she's a brunette.
Tell her to soak her body in warm water before shaving. This will open up her pores. Also, there is this shaving gel called "Coochie" that works really well. It's made specifically for that area and wont dry out her skin either. If you can't get your hand on that stuff dont worry. She can use regular shaving cream. Just don't use regular soap...
After she shaves, tell her to apply either balmex or desitin (diaper rash creames). Don't wipe it off. Leave it on overnight and the red bumps will be gone
