How Long Does It Take For Your Eyebrows To Grow Back After Waxing?
I was at a party and I thought it would be fun to wax off my eyebrows off.
I got told it takes 7 years, but that can't be right.
Can anyone help me out here?
And please be serious, and don't tell lies.
I look like a freak, lol..

lol..one night(alcohol was involved) I singed part of my eyebrow off.
it took me about two and a half weeks.

hope this helped, let me know, =)
