One of the biggest time-depleters in the morning? Your hair. Sure, you can swipe on some lipstick in the parking lot before you head into the office, but good luck fitting your blow dryer and your curling iron into your purse (let alone finding an accessible outlet). And yet, nothing lets the world know you hit snooze a dozen times like bed head, cowlicks, and noticeable dry shampoo overload.

As a night owl who shudders at the thought of wearing buns all week in order to get out the door on time, I'm happy to report that ingenious "overnight" hairstyles exist. With these five hairstyles, you do your prep work the night before, so you can wake up, shake it out, and go. The cherry on top? The main ingredient for all of these hairstyles is something you (hopefully) have a steady supply of: sleep. No crazy texturizing treatment, no damaging hot tool, just a pillow and some good old-fashioned z's.

Want to skip the dry shampoo and wake up with Bridget Bardot volume in the morning? Sleep in a trendy topknot.

1. Start with damp hair, and apply a frizz-taming lotion throughout.
2. Flip your head over, gathering all of your hair into a ponytail at the very top of your head. Use a soft bristle brush to smooth the top and sides of your hair as you go. Secure with an elastic. (Keep it looser than usual to avoid tugging overnight.)
3. Wrap the ends of your ponytail around the base of the elastic, forming a bun. Secure the ends at the base of your ponytail using bobby pins. Mist with a hairspray, like Sexy Hair What A Tease, $15.71, to recreate that just-teased volume and hit the hay.
4. Wake up and let your hair down. Lightly brush through hair with a soft bristle brush and lift at the roots for added volume. Re-fresh with hairspray if needed.

I'm not sure who wouldn't want to wake up in the morning looking like Veronica Lake. To get true retro waves, ditch the curling iron and follow the path of vixens past with classic pin curls.

1. Apply a workable texturizing cream (we like Pureology Texture Twist, $22.10) to damp hair, then create a deep side part and have several bobby pins on deck.
2. Start at the front of your head and take a two-inch section of hair. Wrap it multiple times around two fingers, then carefully remove your fingers while maintaining the curl shape.
3. Pin the curl to your head using a bobby pin, and repeat this process until you've pinned all of your hair.
4. Once you've completed your entire head, add a second bobby pin to create an X shape so your curls don't budge once you lie down.
5. Wake up, remove all pins, then brush your hair using a boar bristle brush. Brush until your curls start to resemble loose retro waves.

Thse perky rag curls will put some pep in your step even before you start guzzling the coffee.

1. Create a side part in damp hair and spritz a curl-enhancing spray, like Tresemme Flawless Curls Spray Gel, $4.99, throughout.
2. Rip up 1-inch wide pieces of an old t-shirt or pillowcase, and roll a 1-inch section of your hair up around the paper towel toward your roots.
3. Once you reach your scalp, tie the ends of the paper towel together to secure the curl. Repeat this process until you've rolled your entire head.
4. Wake up and remove the paper towel pieces. Use your fingers to gently separate the curls as desired. Lift at the roots and finish with a mist of strong-hold hairspray.

It may be hard to believe, but a little frizz can look pretty. Crimped hair has reemerged on the beauty scene with a more modern spin on the 80s staple that is less prom and more runway chic.

1. Apply mousse, (Paul Mitchell Sculpting Foam, $23.49, is a top-rated pick) to damp hair, focusing more on the length and avoiding your roots.
2. Separate your hair into four sections, then braid one section, starting as high up as you want the crimps to fall, and secure the end with an elastic.
3. Repeat the process on the three remaining sections of your hair.
4. Tie your four braids together to keep them in place while you sleep, then hit the hay.
5. Wake up, and unbraid your hair. Then, use a paddle brush to brush through your hair and create small crimps.
6. Finish with a moveable hairspray.
