It's true that over plucked eyebrows might not grow back but 7 weeks isn't long enough to draw any conclusions. Give it more time. If you did scar yourself for life, at least you're in good company. I think we've all plucked our eyebrows into oblivion at some point.
 

My mom was a beautiction for years before getting married. She's always told me that if you pull a hair out by the roots enough times eventually the root dies and the hair won't grow back.
Seems to be true for my eyebrows which she started waxing for me in elementry school as I had a major monobrow going on. Wish it was true of the dark black wire-like hairs growing out of my chin that I have to wax weekly and tweeze daily! *mutters* Pay over a $1,000 in laser treatments and still have them growing....

Thanks for all the responses. I have also heard anecdotal evidence that castor oil will help, so I may try it since it is so inexpensive. I've also heard of using Rogaine, but I don't think I'd go that far. JamiSings, I hear ya with the stubbornness of unwanted hair: areas I've plucked for years (dark stray nipple hairs!) come back faithfully in two weeks, but nooo, not my eyebrows! Frustrating.

Bethe - I remember as a kid when they first found a "cure" for sweaty palms they talked about it on the news, saying that they actually would suck out the excess sweat glands. That's about the time I realized how hairy I am compared to other women. Most women can skip a day of shaving. Not me, I have to shave every single day. I kept thinking "If they can do that for sweat glands, why can't they do that for excess hair?" I mean, they do hair transplants, right? So why not hair removals?

I'm using myself as a guinea pig for the great lash experiment. As I've started using castor oil on lashes only. My eyebrows are ok, I never really tweezered when I was younger. My eyebrows didn't figure in my list of things to change; spottinness, hair were much more my concerns ;) So far, no real change but I'm not fully in the habit yet. But I have noticed that the next day if I use it at night, mascara seems to make them longer. So just by conditioning them it might be making a change. I know the Brains will advise that I should do one eye only in order to have a control lash, but I thought I'd go for both and if I think there's a real, discernable difference stop using it on one eye to see if they reduce. I just don't fancy looking like Malcolm McDowell from Clockwork Orange, even for a few weeks though ;)
