I dreaded eyebrows. I used to shy away from the brow part since it was my main weakness and I'm not alone. Alot other people I know hate eyebrows as well. Sad as it may say though, eyebrows are crucial in makeup. For one thing, they frame the face and it somehow "completes" it. Do makeup without eyebrows and it's practically like, uhm...cheeseburger without the cheese.
Even if anatomically speaking eyebrows may be a teensy fraction of the face, it actually can alter the mood and expression, depending on its shape, color, or volume. Depending on the technique, product, or shade used, eyebrows can make a person look differently or convey a different mood. Take a look at these photos for example..
As you can see, that's the same eye with the same eye makeup 
but if you notice, they both look different (I got this idea from Kevyn Aucoin's book Face Forward, with Isabella Rosellini as the model. Here, I use my eyes). The filled-in brow (right) actually makes the overall expression stronger than the subtle, casual brushed-and-gelled brow (left). So, there you go with the product used. if you want a natural look, just brush with gel. If you want more definitaion but subtlety, use powder to fill in. If you want uttmost definition.. whip out those pencils, girl!
Also... notice the difference:
The brow on the left is a filled in brow... and see how stronger it is than a naked brow? It's cool to note how a tad of definition can change the overall appearance.
Now don't get scared, ladies. Here are some tips for the kilay-phobes out there!
1. Get those eyebrows groomed. Nothing else says clean and put-together trhan a pair of well-groomed eyebrows. For brow virgins, you can get a professional to do that for you and if you're just as scared to pluck them yourself. Ask a friend whose brows you love where she gets hers done. TIP: I prefer threading or plucking as opposed to shaving, where regrowth is slower. I get mine done professionally then maintain it using tweezers. If I need a "booster," I just go back to the partlor.
2. Maintain those lovely brows. After major brow manicuring, it's now your job to get that perfect arch maintained. Ask the brow aesthetician how to maintin them. Pluck stray hairs when you see them. Soon you'll get used to it.
3. Color - the rule is: the brows should be 2 shades lighter than the head hair color, not darker. Black is too harsh and aging and can make a person look older than she really is. We can't go wrong with a light blond shade. Also, it's safer to get a lighter shade (try MAC brow shader in Walnut or Paul and Joe eyebrow pencil in #04) and build gradually than harsh shade. Another tip: blond mascara looks great with those summer blond hilites. The look is gentle but not fake (try MAC brow set in Sophisticated).
4. Find a technique that's yours - whether it may be simply lining the brow or a bit of powder or throwing the big guns of eyebrow pencils... just practice and see which one looks great on you.
5. If there is no arch, don't force an arch. Keep brow shape natural. The best brow shape is what nature gave you... all you need is just to keep them clean. Fill in brows where they ought to be, not where you want them to be.
6. To make waxy brow pencils stay put, dab some eyeshadow/eyebrow powder (same way as setting foundation). For eyebrow colors that tend to get red, neutralize with a brown with a green undertone like Elegant Minerals in Khaki. The result is very serene and subtle.
7. Less is more. Apply less product first and build on as you go. It's better that way. trust me.
So that's it for brows! Hope all you girls learned a thing or two. I promise, once you get the hang of it, you'll love brows as much as I do and start playing around them. Practice with your weaker side, and see what techniques you have. :)
Brows are my weakness too.
