1. To get Leslie Mann's hairstyle, apply a heat protectant to damp hair and blow dry straight using a paddle brush.
2. Once your hair is dry, create a side part. Then, use a ceramic flat iron to straighten your hair, focusing on the roots.
3. Use a boar-bristle brush to smooth your hair flat against your scalp, then pull your hair back into a tight mid-height ponytail. Secure with an elastic.
4. Finish with a strong-hold hairspray.
