if anything i see this only in a symbolic realm. dw has said he was guided to grow his hair to 4" or longer to improve his abilities. i'm not sure if this has scientific backing or not... but when we look at it symbolically, we can see that as longer fingernails mean you can scratch deeper, longer hair could mean you think deeper. maybe if there were light of evidence showing strands of hair acting like antenna of some sort, then we could postulate that it's picking up thought essences lingering in the cosmos.
