1. Wash and deep condition your hair.
2. Warm up your curling and/or your crimping iron.
3. Brush or comb out your hair, and part on a side.
4. Her hair is slightly messy, so make slight curls and waves with your irons.
5. Another alternative to this is to spray water with sea salt in it on your hair with a spray bottle. This will make slighter waves, but almost the same effect.
6. (optional) Spray with Hairspray.
