Simulated hair isn't affected by force fields? I have uploaded a blend file with a "Wind Blowing Hair Test" and it is my hope that perhaps someone can offer some assistance. I utilized a UV Sphere and applied a particle system along with a pair of "Force Fields - Wind" and the hair falls to the bottom of the sphere leaving the top bald while the wind force retains little movement. Any ideas would be great!

I noticed two issues with the wind forces, they are quite weak and they are facing the wrong direction.

The affected axis (under Falloff, next to Power) was set to -Z (in local coordinates), but the force fields have their positive Z arrows pointing towards the object.

Increase the strength and set the axis to +Z:
