Coming from a culture able to create jewels capable to emit their own light, vials that trap the light of a star, or ropes that untie themselves just by telling Galadriel's name, or cloaks that could take up the hue of their natural background, or stones able to transmit images from other stones, or travel bread that could be kept indefinitely and sustain just as much broken than whole, or Rings of Power and so on, I believe that mastering the hidden art of the buzzcut is within their grasp.
It's just nitpicking at this point. Granted, it is much easier to pick nits in a short hairdo than in a full mane of hair...
