Mary-Kate Olsen

Mary-Kate Olsen's super-long Rapunzel hair works best for thick-haired ladies looking to sneak a man up into their castle. Get the look: 1. If your hair isn't this long you might want to enlist the help of some good ol' clip-on hair extensions. Make sure you invest in some good ones though or else hair tends to look ratty.2. The night before you want to wear this style, apply some curling mousse to wet strands.3. Then, create one large French braid starting at you crown and going all the way down to your ends. Get your beauty sleep, princess.4. When you wake up, before letting your braid loose, blast it with some heat from the blow dryer to make sure it is completely dry. Shake braid loose and finger comb your way into wavy perfection. Add the extensions in if needed.5. Mist with a flexible-hold hairspray.

Mary-Kate Olsen's light brown layers add texture and volume to fine, straight hair. 1. First, prep damp hair with a shine serum.2. Blow dry entire head with a flat paddle brush to get rid of any kinks and to get a straight, even style.3. Using extra large hot rollers, roll the top layers of your hair up and let hair sit on heat for about 10 minutes. Velcro rollers work too, you just need to blast them with heat from a hair dryer and let them sit on for about 30 minutes. 4. Let hair loose from rollers and shake out, finger combing to combine the waves with the rest of your hair. 5. Designate a sexy side part and use a bit of wax on the tips of your layers to perfect Olsen's messy look.

Mary Kate Olsen's wavy hairstyle is so boho-chic. Steal her style: 1. Before you go to bed, rub a texturizing product through damp hair and create two semi-tight French braids on each side of your head. 2. The next morning, take out the braids and use your fingers (NOT a brush) to separate and loosen up your waves. Touch up any straggly ends with a curling iron3. Slip on a braided headband that matches your hair color for an extra bohemian touch. Or, if you're feeling ambitious, create a French braid starting at one ear and over to the other. Use your fingers to make it looser and messier.
