Hmmm, I know Lugol's solution helps to dissolve scars (and skin!) and the BF&C has herbs that 'dissolve' as well as herbs that 'regrow'.
Being cautious not to 'overdue' with the Lugol's, I'd get them good and irritated using that, then apply BF&C to the irritation for the healing & regrowth.
But that would DEFINITELY be "an experiment" - insert typical disclaimers here!
