Abstract
The black hole no-short hair theorem establishes a universal lower bound on the extension of hairs outside any 4-dimensional spherically symmetric black hole solutions. We generalize this theorem beyond spherical symmetry, specifically for static, axisymmetric hairy black hole solutions and prove that the "hairosphere"must extend beyond the radial extent of the innermost light ring.
