Blender importing animated character with two rigs

Problem importing animated character from blender to unity.

I have a character who is rigged and has a run cycle animation. I have parented a ponytail mesh and animated the movement of the hair while the character is running. So in blender the hair stays on the characters head and animates while the character is running.

I've imported the file into Unity and the hair animates but the body doesn't.

Does anyone know what I have to do so that both animations run at the same time?

Thanks
