There are some hair styles that withstand the test of time. These styles look good whether it is 1920 or 2008.
Timeless classic winning hair style goes to Michelle Pfeiffer. She is wearing a long, layered hair style that looks great whether curls or straight hair is in style.
The layers start at about chin level and taper down from there. This type of hair style will require a little extra work to keep the layers in place. Also, frequent trims are helpful for keeping the layering well positioned.
Runner up goes to Tom Cruise: This classic men's hair style will never be out of style. Layering is slightly longer on top, with the sides and back shorter.
