1. To get Jessica Alba's hairstyle, apply a texturizing mousse to damp hair and scrunch the hair up with your hands.
2. Next, spray your hair with a heat protectant and blow dry using a diffuser, taking small sections at a time.
3. Once your hair is dry, part it down the middle and scrunch in another quarter-sized dollop of mousse.
4. Finish with a light hold hairspray.
