"You straighten your hair just to curl it again?!" I've been asked that question incredulously several times, and the answer is, well, "Yes!". With natural curl you can't get the soft waves that curlers grant, so I straighten all the layers before setting them on hot rollers.
Today it didn't work as well as it could have because it was so cold (2 degrees) that my hair was static and dry. A little moisture in the air is best. The overall look five hours after the hot rollers came out, with no hair spray, is below. My bangs are swept to the side because they are too long to be across my forehead; this style would look better with the bangs.
