Oh my, could this group be called the Splint Enders's ? Kinda hairy... almost sounds like a Rock Band. Michelle on the mike, Sir Elf on the horns, and Oneironaut on the drums. I'd pay to see this
Don't put me on drums, I can't keep a steady beat to save my life. If I were in a band I would be more along the lines of the guy in Mighty Mighty Bosstones that just dances in the background because he can't sing or play an instrument, yet his friends still took pity on him and let him be a member even though he dances like he's having a seizure.
Back around to the har topic: Thinking more about "potency" in the hair brought to mind the opposite end of the spectrum, as I understand that there are those who purposely have kept their hair short or shaved, not due to length having any consideration for their personal power, but moreso to prevent others from using hair clippings against them through sympathetic magick.
I was taught that a hex/curse could be further empowered by having a focus item of personal nature to the intended target. Hair, nail clippings, blood, etc are about as personal as you can get...and hair is usually the easier to acquire stealthily (of a physical nature at least).
