The tendency to overcorrect or add too much flare can leave you with a terribly embarrassing pair of brows. To prevent

1. Don't over-tweeze. It can take a full eight weeks for the hair to grow back. That's a long time to suffer from an avoidable mistake. Always follow the "less is better" approach.
2. Don't carelessly yank out hair while tweezing. You'll run the risk of breaking off hair at its follicle base and causing an ingrown hair infection. Pluck one hair at a time and always in the direction they are growing.
3. Never apply an eyebrow color that doesn't match your hair exactly. Going even a shade darker will create an unflattering and terribly fake look.
4. Never pluck one eye at a time. It's crucial that you continually alternate from eye to eye to achieve a symmetrical look. If you focus on one brow first and accidentally over-pluck, you'll wreak havoc on the other eyebrow as you try to even things out.
5. Never wax your eyes by yourself. This should only be done by a professional. The risk of getting hot wax into your eyes is too great to chance it.
6. Never extend eyebrow liner (colouring) more than a quarter inch away from the natural hair line. If you do...the fake "hair" becomes too noticeable.
