My husband bought me the TARTE eyebrow kit a little while ago. I love it!!!
It is a teeny little kit (small 'nuff to fit right into your mini-purse, or makeup kit). I believe they have three or four different shade choices for blondes, brunettes, etc. The kit contains: A colorless brow wax (this is great), a brow powder, a teeny lil' brow pencil (this is so cute; it's small, for sure...but it works!), a teeny pair of tweezers (again..small..but they get the job done..I've used these several times when I'm in the car and spot that 'stray hair'), a mini brow gel, aaand last, but not least, it comes with three universal brow stencils plus instructions on how to get your brows looking their 'best'. I wasn't really that cheap, but with the mileage I've gotten out of it (with more to go!), I'd say it was money well-spent! Oh...did I mention the box is pink...and everything has it's own little "spot"...There is a compartement that 'twists' out (hard to describe) to reveal the brow powder and wax. SO adorable!!
Another good choice would be one of Anastasia's kits (she's the brow-guru to the stars)...They are expensive, but they have some great stuff in 'em. There are several varieties of kits (and items you can buy seperately)...and they are customizable for your coloring and needs. I've heard wonderful raves about these.
OR....Benefit Browzings...again, these come in a few different shades, and anyone I've ever heard from that has one of these kits LOVES it!!
Go to the Sephora website, and go to their "brows" section...you'll see literally TONS of stuff to choose from (it's almost dizzying)...Most every company has some sort of brow-product line, or kit...I hope I've narrowed a couple down for ya!!! Good luck, and have fun picking one out!
