Summarize the following:
Once your bun is finished, you can tackle the bottom section of hair. You certainly don't need to use a curling iron or a straightener on the bottom section, but you can if you want. Skipping the hot tools is the easiest option, and rocking your hair au natural. The great thing about this look is that it is messy and carefree, so it doesn't require meticulously curled or straightened hair. Use a comb or brush to tease the underside of this hair at the root. This will add volume to this section, so that it doesn't hang limply. Since you added volume and texture to the top section, you want to make sure the bottom section has it as well. Once your top knot is perfected and your hair is styled, secure it in place. Spray your favorite hairspray, focusing on the actual top knot. Don't spray much on the hair left down, because you want that hair to look soft and touchable. Use a handheld mirror to double check that everything looks good from the back, and enjoy all of the compliments you're sure to get on your half up top knot!
Style the bottom section of hair. Tease the hair left down. Add hair spray.
