Defining brows with a pencil can sometimes look too obvious. For a naturally filled-in finish, I recommend toning brows down. If you prefer to use a pencil, always choose one that’s a couple of shades lighter than your hair color. Even if your hair is the darkest brown, try using a dark blonde or taupe-colored pencil. I suggest to use pencils that turn to powder or eyeshadows are good to fill in & then shape it.
