Speaking of granny hair, it's time we reconsider the humble pin curl. What could be simpler than styling your hair with bobby pins? This heatless hair style is ideal when you have some time to kill, e.g., eight hours of sleep or a lazy afternoon binge-watching "Transparent." And, with a little practice, the end result looks so polished and pretty.

When hair is slightly damp, work in a light-hold styling product. Grab 1.5-inch sections of hair and roll (don't twist) each section up to your scalp, pinning them with bobbies. Kick it while your hair dries, then unpin your curls and brush them out. If the curls are too tight, don't freak out; a water-based salt spray like Herbivore Coconut + Sea Salt Beach Wave Hair Mist will relax your Shirley Temple tendrils into sexy, Blake Lively waves.

"Wrapping your hair in a loose braid overnight for movement is an easy style trick," says Leal. But what if you're after ripple-y, princess waves instead of the beachy, crimped look you get from wearing your hair in braids?

The rope braid -- created by sectioning the hair into two pieces instead of three, then twisting it together -- is an easy way to get pretty waves overnight. Start by separating slightly damp hair into two sections, twisting each section away from the face, as you wrap those sections around each other. (If you're scratching your head, here is a great video tutorial.)

When you take your hair down in the morning, fluff and brush your waves, then add body with a thickening styling product. Leal recommends dry texturizing spray, which she says is great for adding "lift at the root." Try IGK Down & Out Dirty Spray.

Manipulating a blow dryer while you wrangle a round brush takes a lot of coordination. For a DIY blowout that's a lot less cumbersome, try a hot-air brush. If you prefer a sleek blowout, check out the Revlon Pro Collection One-Step Hair Dryer and Styler, which is paddle-shaped for maximum smoothness; to get a voluminous look, try the Sultra Vixen Volumizing Dryer Brush.

Start by rough-drying hair with your usual dryer. Then, pull the hot-air brush through hair with long, slow passes from scalp to tip, maintaining tension. When your hair is nearly dry, try focusing the brush on your ends, gently rotating your wrist away from your face. Your at-home blowout will have a pretty, fresh-from-the-salon flip.

What if you love that mermaid-wave look, but you don't want to mess with a round brush or even a curling iron? If your hair has a slight natural wave or curl, creative finger-styling while blow-drying can make all the difference.

First, coat barely damp hair with a styling product like Amika the Perfect Body Whipped Mousse. Separate your hair into large sections and twirl them into tight twists. Blast the twists with your blow dryer on the highest heat setting, then hang out while they cool. When you shake them loose, your waves will have blowout-like bounce and uniformity. Finish things off with dry texturizing spray or hairspray.
