So, I was thinking of making a custom fragment shader to displace the texture with noise, so it will look that the hairs are moving with the wind, but I don't know if I can do this, legally talking.
The result would be something like this:
I'm using UV displacement, and created a alpha mask sprite with the regions that I want to offset (the region in the eyes, for example, the mask alpha is 0.0, so there isn't any offset), and OpenSimplexNoise texture.
