Hair Tool is add-on for Blender that will help you generate hair-card, shell hair or curve hair in non destructive way, using geometry nodes and python.
For Blender 3.6 – use Hair Tool 3.x (only new hair curves are supported) – and Hair Library 3.0_date
For ‘old’ Blender 3.3 up to 3.6 use ‘old’ Hair Tool. 2.46 (last version that supports ‘old’ curves) – use HairLib_18_12_2022 with it.

There are multiple ways to generate hair-cards with Hair Tool:
Hair System – procedural hair generation based on geometry nodes – great for all kind of complicated hair styles (braids, curls, punk etc)
using Guide Mesh (grid surface) – best for modeling long hair strands – now rewritten to use new hair curves, in HT 3.0
using Track To Mesh – great for short to medium hairstyles
interactive grooming – old method that uses particle hair to generate hair-cards, replaced by Hair System
drawing and extending hair strands similar to Grease Pencil drawing – now rewritten to use new hair curves, in HT 3.0
using short hair modeling method – for short to medium length hair – animal fur, short human hairstyles
using shell hair modeling – great for very short hair (fur, carpet). Bit complicated to setup in game engine.
Some of the features:
tools for curve based hair modeling (cutting, extending, deforming etc) – rewritten to support new curves
automated UV workflow (you can define uv regions, which can then be automatically assigned to hair strand)
easy hair rigging and animation with Jiggle physics
hair library that contains various hairstyles and sub-components,
various adjustable ribbons profiles – Mesh Profile, Curls Profile, Circle, Flat, Braids etc.
convert: Curves to Particle Hair, Particle Hair to Curve ribbons, Curve ribbons to mesh ribbons and so on.
curve resampling and decimation (increases/decreases curve points count)
generating vertex color/weights gradients, transferring UVs and vertex weights from character to mesh haircards.
texture baking from new hair curves; supports: normal, ao, diffuse, tangent, ID, root, flow and more maps
