We show that in all theories in which black hole hair has been discove
red the region with nontrivial structure of the nonlinear matter field
s must extend beyond 3/2 the horizon radius, independently of all We a
rgue that this is a universal lower bound that applies in every theory
where hair is present. This no short hair conjecture is then put forw
ard as a more modest alternative to the original no hair conjecture, t
he validity of which now seems doubtful.
