Any Hair Any Mesh - Hair Utilities is a Blender addon built around transferring hair from one mesh to another in a single click, without artifacts. It groups several hair-related operations into one set of tools.
Transfer Hair copies all hairs from the active object to every selected object in one click, provided the origin and transform match. Apply Rot Scale applies the rotation and scale of a mesh carrying hair without destroying the grooms. Match Origin sets the pivot point of selected objects to the active object's origin, and Bald Head removes all hairs from selected objects. All features are reachable from a pie menu via Shift+Alt+q, with a second pie menu for particle editing brushes available in particle edit mode. Version 1.2 added the option to transfer only selected hair from the active mesh and to keep existing hairs when transferring.
The addon runs on Blender 2.93 through 3.2, ships with documentation, and is offered under a royalty-free license.
