1. To get Katherine Heigl's hairstyle, apply a straightening serum to damp hair, then blow dry straight using a paddle brush.
2. Create a side part, and mist hair all over with a heat protectant spray.
3. Next, use a ceramic flat iron to smooth any untamed pieces. Then use the flat iron to gently wave your front sections of hair away from your face.
4. Mist a shine serum throughout the length of your hair, then finish with a flexible-hold hairspray.
