  We introduce a new set of chemical variables for the accelerating black hole.
We show how these expressions suggest that conical defects emerging from a
black hole can be considered as true hair -- a new charge that the black hole
can carry -- and discuss the impact of conical deficits on black hole
thermodynamics from this `chemical' perspective. We conclude by proving a new
{\it Reverse Isoperimetric Inequality} for black holes with conical defects.
