For this look:
Ask for caramel highlights if you have dark hair. A few strands around the face would be gorgeous. I recommend the balayage method when getting highlights on dark hair.
Long hair requires some layers to keep it from going limp and A-line (pouffy at the bottom). Ask for long layers that hit at the chin and the collarbone. Shorter hair? Start the layers at the cheekbone.
Long, side-swept bangs are flattering on thick long hair, such as Cruz's.
Don't grow your hair this long if your face is long, or oblong. This look better suits heart-face shaped girls and those with round faces. Long hair draws down an already long face.
