Unbelievably good. I've never had somebody be so attentive to my face before, including my mom. My beautician literally plucks out ONE hair, exclaiming that that one hair can make all the difference. I don't question it, because my beautician knows my eyebrows.
I love how she wants you to look as beautiful as possible, even by that one tiny strand. She commented on how my eyebrows (though threaded) did not look even, but 15-20 minutes, my two eyebrows were shaped and matched.
Love her work! Albeit a bit expensive, but so worth it. Your eyebrows are essential features of your face, so treat them well!
