As Ali, a girl who moves from a small town to pursue her dreams in LA, Christina Aguilera's character goes from sweet to sexy as part of the transformation. To get her wild waves:
- On dry hair, use a small-barrel curling iron to create spiral curls, alternating the direction of the iron as you move along the entire length of the hair.
- Use your fingers or a wide tooth comb to lighten the texture and create volume.
- Spray on a humidity-resistant, moldable spray. Samuel used Sebastian Professional Re-Shaper.
