Unstructured updos get dressy with delicate hair jewels.

Easy and elegant, this updo will last all night. Hair is parted from ear to ear; the back section is lifted, given a twist and secured against head. Back-combed front pieces are smoothed away from forehead, then bobby-pinned, disguising the twisted section, while hair ornaments create the gentle chignon. Perfect product: Fight fuzz with Pantene Pro-V Frizz Control Extra-Strength Serum.
