Spirituality and hair length

[Reaper]

I think culture has a lot to do with this phenomenon. In a culture where long hair is commonplace or even regarded as sacred, suddenly having it cut could easily produce psychological and even physical symptoms, whereas in a culture where it is common to be bald (such as in a Buddhist monastery), being forced to grow out one's hair could have just as detrimental an effect.

You definitely do not need long hair (or any hair) to have psychic abilities.
