1. To get Christina Aguilera's hairstyle, apply a straightening serum to damp hair and blow dry straight using a fine-tooth comb for your bangs and a round brush for the rest of your hair.
2. Once your hair is dry, spritz your hair lightly with a heat protecting spray. Then run a flat iron through your hair, flipping the ends slightly outward as you go.
3. Mist a shine serum over your hair to finish.
