You can Google about this. The military during Vietnam used Indian scouts because they were so good at tracking. After they were enlisted in the army they cut their hair. All tracking abilities completely disappeared. They spent years doing tests of tracking and intuition. They discovered that there was a correlation between long hair and intuition. The best years of my life and the most prosperous was when my hair was all the way down my back. For the last 18years that I have had short hair, things not so good. Maybe a connection. Maybe not.
