HairClump is a Blender add-on that parametrically controls the randomness of hair shapes. Multiple controls based on clumps—length control, kink control, and other various controls—makes it easier for users to style a complex hair shape through the simple guides.
Hair_Extension_Toolkit is an add-on that highly enhances the controllability of the hair in Blender. There are many practical functions, like merging and splitting particle systems, resetting the number, steps, and length of the guides, applying the effect of children to the guides, recording the hair selections (There is a PieMenu about hair selections), etc., thus greatly helping users improve the efficiency of the creation of the hair.
HairShapeKey is a Blender add-on, supporting adding shape keys of hair, making it possible to record the transition between multiple shapes of hair-like models. Users can switch between the different shapes freely, keyframe animation, and set driver control, which makes it more controllable to style hair. Just have a try!
