No, it's ugly (and I don't say that word much) and you will surely regret it later. It's almost as bad as permanent eyeliner. Eyebrows offer your eyes protection as much as eyelashes, it's like a natural sweat band.
NO WAY HOZAAAAYYYYYYYYYYYY! that would be the biggest mistake ever (unless your eyebrows are falling out). I dont understand why girls pluck their eyebrows down to little thin lines, look at Audrey Hepburn.
