Whenever I've had issues with static, I will get my run tangle-less brush under water, bang it against a towel a couple of times and then brush my hair with it.. generally I have to wet it a few times to get all of my hair a tiny bit damp... That usually works for me.. even after the water has dried..
If not, then I put in a leave in conditioner.. Something I'm looking forward to trying this winter is coconut oil, in a very small amount, I'm sure it will help, and it's very good for your hair.
Plus, you could use Aloe Vera Gel, it works great as a hair gel, doesn't really build up, and is also good for your hair.
