How to use curves to style hair in blender 2.79?

I’ am not able to style hair with bezier curves (in the Hair Force field settings I have selected the option curve guide but nothing happens-- see the attached .blend file curve-guide-hair.blend (945.1 KB) --)
Where am I doing wrong?
Thanks in advance

I don’t use this method any more but this is one way to do it.

Thanks, now it works. (I had not enabled Physics for the bezier curve)

So glad that my lazy response was useful. :sunglasses:
