Thank you very much for your answer Brent, i ended up trying this also, but the puppet tool messed up when the camera started to move. I was on a bit of a hurry so i opted for breaking the hair in the individual hairs and faking the wind blowing with a turbulent displace on each layer of hair, offsetting them a bit so they didn’t move all the same. I didn’t have a lot of control, but it was good enough for the purpose.
Have a nice day!
