Those of you with longer hair might consider some changes in your hair routine. The motion to flip your hair either to the front or to the back again can be enough of a motion to your brain that it can cause symptoms to persist or relapse.

I sort of cringe when I see women flip their head from side to side to get hair out of their face. This same motion would stop me in my tracks.

Remember the term Sub-Concussive impact. Those are the motions that cause subtle traumas to the brain that do not cause immediate symptoms but combine to cause much more serious symptoms.

On a scale from 1 to 10, you may have suffered a 6 or 7 concussion and needed to recover. Later, you can suffer multiple 1 or 2 sub-concussive impacts that combine to cause symptoms much worse than the 7 concussion. That hair flip may only be a 1 or 2 but can cause havoc over the long run. There is sound science to back up this claim.
