Ever wondered what the heck that spiky brush is on the end of your eyebrow pencil? Or what those cheap wands at Sephora are good for beyond the makeup counter?

Well, my friends, this brush is formally called and "spoolie" and it can be your best friend if you know how to use it to its full potential.

1. Tame baby hairs and fly-aways

Ever put your hair up in a perfect pony tail, but your baby hairs and unruly strands ruin the look? Put some hairspray on your spoolie and brush through those hairs! The spoolie is small enough to perfectly get those small areas and can put the right amount of product on your hair without making it overly crunchy and noticeably hair sprayed.

2. Clean up mascara mistakes

It's always awesome when you put effort into your eye look and start putting on your mascara! But it's not so awesome when half of it gets on your eyelid instead of your lashes (we've all been there).

But fear not, your look can be saved! Just wait for the mascara to dry for a few minutes and brush it off with, you guessed it, a spoolie. It'll crumble right off and your eye will look like nothing ever happened! Just make sure to do it after it dries so the wet mascara doesn't smear.

3. Clean up liquid eyeshadow

I have recently been really into applying liquid eyeshadow with a doe foot applicator this summer, but the downside is that it always transfers from my lid to my crease! To clean up, I wait for the eyeshadow to dry and run the spoolie along my crease to get rid of the extra shadow. Like the mascara, it should crumble once ran across with a brush and come right off.

4. Un-clump your lashes

If you're as picky with your mascara as I am, you know that it's the worst when you are going for a voluminous look but your lashes won't stop tangling together. To fix this, grab a dry spoolie and run it through your lashes to get rid of the clumps and tangles. This works better than a wet mascara wand because the dry brush will take off excess product and allow your lashes to separate instead of clump further from the mascara's moisture.

5. And obviously, get your brows on fleek

One of the most popular ways to use a spoolie is as an eyebrow brush, where you can brush through the hairs before filling them in. Spoolies are oftentimes attached to eyebrow pencils and paired with brow pomades. Using one of these will filling in your brows will help make the pigment disperse evenly, making the brow look more "natural" and faded out. In addition to this, you can also spray your spoolie with setting spray and set your brows to make sure they don't move throughout the day, like the baby hair and fly away hack listed above.
