Apply texturizing spray to dry strands. This will give hair more grip when you lock in your chignon with bobby pins. After a few spritzes, part your hair to your liking -- a center part is a pretty go-to. Starting at the top of your head, create a section of hair on both sides in front of the ear and forward. You can secure the sections of hair with a hair tie or allow them to rest free for now -- whichever is convenient for you. (Those with mermaid-like long hair might want to tie back.)
To give your chignon a little life and volume, lightly tease the crown for extra oomph. To really amp it up, you can spritz some dry shampoo at your roots before you tease (try Psssst Instant Dry Shampoo, $6.99). Taking the back section of hair (not the two sections in front of the ears), put hair into a low ponytail, and lightly tease the ponytail to add fullness.
Grab a small section of hair from the bottom of your ponytail and wrap it around the base of the ponytail to hide the rubber band, securing the giant strand with a bobby pin. (Minus the major dog ears we've got going right now, this is also a simple way to dress up a basic ponytail.)
Take the remainder of the ponytail and wrap it around the base, until the full length of the ponytail is in a giant coil at the nape of your neck. Secure your chignon bun with bobby pins. You can gently spread the bun apart for a more tousled look or keep it clean. Either way -- do you, girl.
To finish the look, take the remaining hair from the front sections and run a comb through them to make strands smooth. Then crisscross the two lengths on top of the bun in the back, tucking the ends into the bun and securing with bobby pins. For a little extra intrigue (think of those selfies), let a couple of pieces around the face fall, then lock in the look with hairspray.
