Techniques for configuring hair for animation include obtaining a first representation of a set of hairs on a surface and a second representation of a subset of the hairs. At a vertex of the surface, an interpolated hair is generated by minimizing a difference between a shape of a first hair and the interpolated hair. An edit is received to modify the shape of the first hair. At the vertex, a modified interpolated hair is generated by minimizing the difference between the modified hair shape and the modified interpolated hair. The interpolated hair and the modified interpolated hair are projected onto a root of a second hair. Rotation parameters indicating a rotation and a scaling factor indicating a scale difference between the projected interpolated hair and the projected modified interpolated hair are computed. The rotation parameters and scaling factor are applied to the second hair to propagate the edit.
