I have low potassium in my hair. Is there something concerning about having a low level of potassium?

Well, it’s often a sign of anxiety and burnout.  

People who have low potassium in their hair have often gone through some stressful life event or trauma.  

A lot of people who are completely run down by chronic stress end up having low potassium. 

I had low potassium as well.  

So one thing it suggests to me is that you should look into EMDR and neurofeedback. Because low potassium often correlates with trauma and PTSD.
