Here are some video ideas:

- Let's hear the model's voices.. do they speak English? Even if their English is not too good, it would be good to hear their voice.

- Interview them about their life and hair.

- Have a plot to the videos. Are they getting ready for work and their hair is not behaving? Getting ready to meet a new boyfriend and worried how their hair looks? Thing of a haircut and going to the hairdresser's only to back out at last minute?

- Some fake hair cutting or hair play would also be nice. Maybe someone is trying to cut their hair (again, fake!) and they are trying to get away. Perhaps work a kidnap plot into the story.
