Halle Berry is wearing her hair in a long, curly hair style that features a side part.  To create this style on you own, first add a curl-enhancing gel or styling product to your hair.

Blow dry the hair using a diffuser attachment and just your fingers for shaping the hair.

If you do not have naturally curly hair like Halle's you will need the help of a curling iron to create the all over curls and waves.

After curling your hair, apply a shine serum to create the glossy look.
