We show that in all theories in which black hole hair has been discovered, the region with non-trivial structure of the non-linear matter fields must extend beyond 3/ 2 the horizon radius, independently of all other parameters present in the theory. We argue that this is a universal lower bound that applies in every theory where hair is present. This \it no short hair conjecture is then put forward as a more modest alternative to the now debunked \it no hair conjecture.
