I trim tiny bits under my girls eyes so the hair doesn't poke them -
I use these 2 tools - the black for Chanel cause she's a good girl about it
and the personal trimmer with the little comb thingie for Cheri cause it's quiet and she isn't thrilled with a trimmer on her face....but I go SLOW and only a TINY AMOUNT
it's best not to cut it if you don't have to
