The Benefit brow kits are incredible, and if you're more into the natural look, NYX makes a really thin brow pencil that you can use to draw the hairs on individually. There are some really great brow tutorials on YouTube. Just make sure to keep the thicker inner areas of the brows softer. As far as tweezers go, invest in good ones- they'll last you a lifetime. Choose a color a few shades darker than your hair, and if you have cool undertones pick a warmer shade and go with a cooler shade of you have warm undertones. Tweezerman tweezers are awesome, and they have a lifetime guarantee. There's nothing worse than trying to pull out a stubborn hair with a dull set of tweezers. And don't over pluck! I did and my eyebrows never grew back. I had to get microblading eyebrow tattoos to cover the over plucked mess I had.
