for me, it took me about a month to grow back in!.. or i think even less? like, between 3-4 weeks!.. but that's ONLY if you DO NOT pluck them at all! just leave them the way they are!.. and then when they do grow back in.. go to the salon to get it professionally shaped =)

OH! and about the massaging thing.. that may help! because massaging helps blood circulation which i guess may help the hair grow? look at this website.. and you can also go to the links at the bottom of the page! i think it'll help =) .. How to Grow Bushier Eyebrows - wikiHow
