How often do you smudge your nails before the polish dries? I'd guesstimate that eight out of every 10 times I leave the salon, I ding at least one -- even if I logged the requisite time in front of the fan or under the UV light. (Does that thing even work?) And, when I do them myself, I ruin them pretty much every single bleeping time.

But, that was B.A. Before Ashley. She's my sister-in-law and she does the books for a hoity toity spa in Pasadena, Calif. And, when Ashley's not crunching numbers, she's picking people's brains for insider tips. Love that girl.

Here are her top four DIY tips that have been keeping me and my digits smudge-free for going on six weeks now (without having to use one of those "quick dry" polishes that never seem to work):

Tip 1: Allow the first coat to dry for at least five minutes before applying the second. If the first coat's not completely dry, the second one makes the whole thing mushy and you'll have to wait three times as long for the polish to harden.

Tip 2: Use a quick-dry spray. I love OPI RapiDry Spray. It reduces drying time by nearly half and, unlike many others, is in a pump bottle instead of an aerosol can, so it's not harmful to the ozone layer.

Tip 3: Empty out an old bottle of clear polish, wash the brush and fill the bottle with olive oil. Apply the oil (using the brush) to freshly painted nails and it will help expedite the drying process -- and impart a nice (albeit temporary) sheen.

Tip 4: Dip your hands into a bowl of ice water. The cold helps solidify the polish.

I also learned a cool trick for being able to tell whether or not your nails are really and truly dry; when you suspect that they are, gently touch two nails together -- you're good to go when they pull apart without a tacky, sticky feel.

Now that you have these tips, it's time to pick your polish -- this snazzy OPI app will help.

Then see why I'm steering clear of the blue polish craze and whether it's right for you.
