One way to choose a fall hairstyle is to allow a summer cut to grow out a bit and style it a little differently. For example, you can grow a chin length bob into a longer angled bob that falls between the chin and shoulder.
Another idea is to grow a pixie cut into a textured boyish cut with longer fringe in the front. Layer the fringe from the eyebrows to the cheekbones to highlight your bone structure. Grow a long bob into a style that falls just past the shoulders and have a stylist cut long layers that start at the shoulders. Keep the beachy summer waves in a long bob or long layered cut, but incorporate an accessory such as a beanie, a wide-brimmed hat or a thick woven headband.
When making the change, use a clarifying rinse to clean the hair of all product build-up. Consider a color change to a warmer tone or a take the color a few shades darker. Colder weather usually means a dryer climate, so use shine sprays and serums to combat dullness. Add fringe with a new cut or clip-on bangs to change up the style. Consider a simple style change by wearing a ponytail, chignon or bun.
