1. The Angled Brush: This angled stiff brush is used to help you fill in your eyebrows. The angle makes it easier to create natural looking hairs in your brow and to work with the angle of your eyebrows. You want to use this with brow powder but you can also use it to put the wax onto your brows so that the powder will adhere to the brow.
2. The rounded shader brush: This is the most basic and versatile of eyeshadow brushes. You can use it to pack color onto your eye, do an all over light wash of color, put a matte color in your crease, and highlight your browbone. Be sure to use sweeping, not dabbing motions to apply your eyeshadow with this brush. Not only will it make your shadow look better but it will also make your brush last longer.
Now that you have all of these brushes and you've been using them, they're starting to look a bit grody, right? Have no fear, you can wash your brushes. You should actually give your brushes a bath every one to two weeks (or more if you are a working MUA like myself). But what soap should I use, you may ask. The best soap I have found is Dr. Bronners Castile Soap in the liquid form. You need very little to wash each brush. You put a little in your hand, run your brush under lukewarm water, and then swirl it in the palm of your hand in the soap. Then hold it under the running water, gently squeezing it, until the water starts to run clear. Then either lay your brushes on their side or upside down to dry, DO NOT stand them up. The water will run down into the brush and ruin the glue holding the bristles and brush together. Depending on varying factors it can take a few hours to a whole day for your brushes to dry. Here is a picture of the soap you should use:
