Airbrush/Painting Hair

Does anyone ever airbrush or paint on the hair? I have seen photos of painting on the hair, and I was wanting to know how you do this. Do you just use your face paints? Do you add hairspray? I remember in one class I took, the just added a little paint the front of the hair (I think it was for a tiger). I want to know how to do all over looks/styles, etc.

Thanks

I've seen it done with stencils... just held over the hair and sprayed with the regular airbrush make-up. On darker hair, spray white first, then the colours.

I've use sponges to apply cake face paints, and my hands to apply creams to hair too...

Spray the hair with hair spray first not critical but it does a few things -
keeps the hair in place for ease of application and a better looking design and acts as a barrier when applying makeup to clor treated hair. As grey and very highlighted or stripped hair can pick up the makeup color.

Then airbrush is your best application. Use water based makeup like Mehron Liquid only.
