Regular exfoliation + moisturiser after every exfoliating session almost always works. If you keep getting them, it might just be the way your hairs grow or you can invest in the special ingrown-hair creams.
Favorite item atm would have to be my Pink Bunny Bonnet from BtSSB but the cutsew dress I'm getting soon is apparently one of the most comfortable pieces of clothing ever made (not to mention adorable) so we'll see!
