So as you know the Song twins melted their family crests and dipped their hair in it but they'll never be able to cut their hair bc they want to keep the metal in their hair, they can't redo it and they can't cut through metal so they can't cut their hair, what do they do when their hairs to long? Idk just a rando thought.

And isn't metal heavy? Bc then they have half metal hair do they ever get head aches from a heavy head? Or maybe it's light non weight metal?

Last thing how do they make it so that their hair can look like regular hair did they dip each strand in separately? All together?
