Seriously, same exact problem. Someone needs to teach a class where they show us all how to do this. Whenever I fill them in, I look like I'm painting myself for halloween or something. It's always way too dark and way too obviously "filled in". Let me know if you figure it out, lol. Going to try a powder next, like Zazi suggested.
UGH! I SO wish I lived closer to you guys because THIS is what I do for a living, and I'm actually pretty good at it lol!
Ladies come to me with their forlorn, barren brows and, through a combination of will power and sheer, brute strength, ( I don't allow my clients to TOUCH their brows during growout), I'm able to turn their unruly, sparse brow beds into works of art..
(Ok, I know that sounded slightly theatrical and condescending, but believe me when I tell you, it's a process..!) In the last ten years, I've still yet to come across a brow I couldn't marginally enhance, as long as the client would follow my instructions:
Me: PUT THE TWEEZERS DOWN. Lol
I have the opposite problem I have bushy eye brows that grow crazy fast. they drive me crazy. when I last got them waxed I went to a benefit brow bar and the girl was gushing about how great my eye brows were and I was like my caterpillars???? how are they awesome? she said people would love me eye brows because she could wax them into any shape. of course that was a few weeks ago and they are all grown out now even with me trying to keep up with them.
