I love Leslie Mann. I love Leslie Mann's hair, too. This is a quick and easy solution for when you want your hair casually out of your face, and don't want to deal with pinning a bun into place. (Though there are pins involved, beware—but only about two or three!) So! First step: Part your hair, and tuck behind your ears. If you want the front pieces to be a bit looser, pull them out as you lightly hold your hair at your ears. Lightly pull hair into a ponytail to the left (or right, totally up to you!) of the nape of your neck with your hands. Pull out a small section of hair at the very bottom of the ponytail. Secure the majority of your hair with an elastic. Now, take the loose section of hair at the base of the pony and wind strands around the elastic to cover it—stop wrapping your hair around the elastic when you have about three inches left at the base. (Can't wind hair around without getting the ends of hair sticking out? Undo once.) Pin underneath, running pins parallel to your ponytail. Start one pin from the neck and another from the pony-side to ensure no strands of hair escape! If you're into it, curl the hair in the ponytail, or leave it straight for a sleeker look.
