When you can't decide on a hairstyle, go with the one from Rachel Zoe's runway show. It combines side-swept hair, braids and a ponytail. Here's how to get the look:

1. L'Oreal Professional hair stylist Pepper Pastor started by prepping wet hair with L'Oreal Professionnel Densite and then blow-drying. Then, apply L'Oreal Professionnel Perfect Shimmer on the ends and use a flat iron to straighten.
2. Create a part that spans from ear to ear on your crown -- like a headband. Part the front down the middle, then divide each of those sections in half (four sections total in the front section) and clip them to get them out of your way. Pull the back half of the crown part into a low ponytail that lines up with your earlobes.
3. French braid the middle section of each side into a cornrow-like braid. Pull back both braids and pin them to the ponytail.
4. Comb the front section of the hair into a smooth swoop, covering the ears and bringing it back to the ponytail. Pin both sides alongside the braids.
5. Combine the strands you just pinned back with the braids to create a three-strand braid on top of the ponytail. Secure with an elastic.

Usually half-up hairstyles tend to bring '90s moms to mind, but not at the Zero + Maria Cornejo Spring '15 runway show. Here's how to get this decidedly non-frumpy 'do:

1. Phyto stylist James Pecis started by spraying Phyto Professional Workable Holding Spray from roots to ends. Then, blow dry the hair for a fluffy, almost static-electricity texture.
2. Make a deep part in the hair on the right side, swooping the hair across the forehead. Add Phyto Phytolaquie Light Hold Hair Spray at the parting. Using it on just the part will give this element a super clean, graphic finish.
3. For the knot in the back, divide the hair into four quadrants. With the top section held apart, take the left and right sections and tie a knot.
4. After the knot is secure, drop the top section over the knot and tie another knot on top using the same right and left section ends to hold everything in place.
5. Apply Phyto Professional Workable Holding Spray to finish the look.

News flash: Normcore fishtail braids are out, and herringbone braids (a deconstructed version of the fishtail braid) are in. Proof? The gorgeous braids every model was sporting at the Spring '15 Suno show. Here's how lead stylist Odile Gilbert for Kerastase created the look:

1. On dry hair, create a deep part using a tail comb.
2. Starting at the roots, apply a generous amount of Kerastase Paris Forme Fatale to the top half of the hair for a voluminous, wet look.
3. Comb hair back in an upwards wave on each side and secure with clips.
4. Create a cage herringbone braid by parting the dry ends into three sections. Begin crossing the lengths over each other and underneath like you would with a fishtail braid, but keep the middle section of your hair out of the braid until it's braided past your scalp.
5. Loosely deconstruct the braid for added volume and a lived in feel. Spray all over with Kerastase Paris Laque Noire for hold.
6. Finish with Kerastase Paris Gloss Appeal for instant shine.
