Pro Hair is a geometry nodes-based tool for generating hair and fur guided by user-drawn curves. Users define the flow of the hair by drawing curves from the root to the tip on the surface of an object.

Hair volume is managed by creating a secondary cage object, duplicated from the base mesh, which can be sculpted into the desired overall shape. The generated hair acts as a foundation that can be further modified using Blender's built-in hair nodes for additional control and detailing.
