Just remember, there is a big difference between "groomed eyebrows" and DRAG QUEEN.
In the Latin community, it seems its now stylish to have "gay" looking brows; heavily tweezed and arched. Even the str8 guys. Its always so OBVIOUS, and effeminate.
Over tweezing is always a danger because after awhile, they may not grow back.
My suggestion is always go to a professional at first, check their work before you let them work on you, and then follow the tips they give you.
