Summarize this article:

If you want a quick way to combat bed head, hold your comb under running water or lightly mist your hair with a spray bottle. Once your hair is slightly damp, comb it into your favorite style. Another benefit of short hair is that you can use your fingers to create a cool hair style! Just tousle your damp hair, then let it air dry. Protect your hair from heat damage by using rollers. Wrap your damp hair around soft rollers, then allow it to air dry for several hours or overnight (or sit under a hooded dryer). You may need to use a smaller roller in your hair if your hair is very short.  Special styling tools called end papers can help you grip the end of short hair to wrap sections evenly around rollers. If you have to go out while you have rollers in your hair, wrap a pretty scarf around your head. A pillowcase can absorb moisture from your hair, and friction as you move your head across your pillow can cause your hair to break. Protect your hair by wrapping it in a silk scarf before you go to sleep. This will also help your hairstyle last longer. If you don't have a silk scarf, try buying a silk pillowcase.

Summary:
Style your hair quickly with a damp comb or a spray bottle. Try roller setting your hair instead of heat styling it. Wrap your hair at night in a silk scarf.
