Works best on: Chin-length or longer, straight or wavy hair
Hairstyle how-to: Step 1: Apply a spray gel (if your hair is fine) or mousse (if your hair is thick) and diffuse hair, holding your head upside down to add volume to your roots.
Step 2: Once hair is dry, scrunch a dime-size amount of gel or mousse on hair to add a piece-y texture.
Step 3: Take the bottom half of your hair (from the ears down) and secure into a low, loose bun.
Step 4: Next, divide the top portion of your hair into small sections and tease the underside of each section, then twist and loosely pin each one into place above and around the bun, keeping the volume on top.
Step 5: Spritz with hairspray to finish.

Works best on: Medium-length or longer wavy hair
Hairstyle how-to: Step 1: Use a spray gel on hair and blow-dry using a paddle brush for smoothness (hair doesn't have to be perfectly straight).
Step 2: To determine where your part should be, Strahan says to draw a line from the highest point of your eyebrow arch diagonally back. This allows the hair to fall forward slightly, better framing your face.
Step 3: Curl the hair around the crown of your head with a large (one-inch) curling iron, holding it vertically, then place hair in Velcro rollers to set.
Step 4: Use a smaller (3/4-inch) curling iron on the rest of your hair. Curl one-inch sections at a time and wrap them all in the same direction.
Step 5: Once the rollers on top of your head are cool, remove the rollers. Mist a boar bristle paddle brush with light-hold hairspray and gently brush out curls so they form waves.
Step 6: Finish by smoothing finishing cream over strands to smooth flyaways.

Works best on: Long, curly hair or straight hair that has been tightly curled
Hairstyle how-to: Step 1: Divide hair into three horizontal sections and secure the bottom section into a pony at the nape of your neck.
Step 2: Pick up the mid section (leaving out a one-inch piece on each side) and divide it in half. Tie the sections into a knot (like you would tie your shoes) and secure the knot to the bottom pony, leaving the ends hanging.
Step 3: Next, go back to the top section and lightly tease it.
Step 4: Create a side-part. Separate the top mid-section into smaller pieces and twist and pin them around the knot you created in Step 2.
Step 5: Loosely pull back sides of your hair (the ones that are still hanging) and pin them around the pony to hide the elastic, leave the ends hanging.

Works best on: Medium-length or long hair of any texture
Hairstyle how-to: Step 1: Wash hair and let it air-dry.
Step 2: Pull hair into a low, slightly loose, pony, just above the nape of the neck.
Step 3: Take one inch sections of the pony and smooth each of them with finishing cream or shine serum. Twist each section and pin it into place around the pony, twisting pieces around each other to create the knot look you see on Klum.
Step 4: Finish by smoothing finishing cream over the top of hair.

Works best on: Any hair length or texture (but you'll need two faux hair pieces, a bun, like Easihair Elegance Hairpieces, and a braided piece, like Easihair Serenity Hairpieces)
Hairstyle how-to: Step 1: Use a gel or pomade to slick hair back into a super tight high bun. Use an old toothbrush with gel on it to slick every tiny hair back.
Step 2: Attach the dome/bun hairpiece on top of your bun, then wrap the braided hairpiece around it.
Step 3: Use finishing cream or pomade to give hair a final polish and keep flyaways in check.
