1. To get Allison Williams' hairstyle, spray a heat protectant throughout damp hair and blow dry using a paddle brush.
2. Create an off-center part, and then use a 2-inch barrel curling iron to curl your hair. Clamp down and roll the iron up, stopping at eye level. Then, spritz a medium-hold hairspray and hold for a few moments before releasing.
3. Spritz a shine serum onto to your hair, avoiding the roots. Then, brush through your hair a few times to loosen your waves and distribute the product evenly.
4. Finish with a flexible-hold hairspray.
