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.

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.

Update: 4.2.0 – for Blender 4.2+ Last update 30.4.2025,, cant find for 4.2.1

Added Flatten option to clumps,

Updated Default Hair Texture (more variation in strand length and sizes),

Updated Hair Baking setup,

Added option to store Deformer presets,

Added option to reset hair UV to the default layout (new default UV layout for new Hair Texture in HT 4.2.0),

New: added ‘Push out Along Normal’ deformer,

Added option to paste hair system as new System (previously paste could only override active HSystem),

Fix errors in how Hair Systems tree structure is calculated in UI (sometimes indents in HSys list were wrong),

Fix: Curves From Grids – could give bad results when grid mesh was split with ‘Split Edge’ modifier,

Added BiDirectional influence range input mask,

Fix strands overlay drawing on undo-redo,

Switching Hair System type is done in Deformers menu now (fist deformer -strand generator has to be selected),

Updated Noise Deformer: it correctly handles frequency mapping now (e.g. when Frequency input is masked with Influence Range mask), added Vector Offset parameters – for both Uniform and Per Strand noise for precise noise adjustment,

Strands from Grid has new ‘use Count as Density’ option – it helps to give uniform strands density, when same hair system is attached to multiple Grid Guides – with different lengths,

Strands ‘remember’ now mesh island ID from which they were spawned from – this way strands spawned on border between two mesh islands will behave nicer when using e.g. Track To deformers,

Added: option to store (single or multiple) Hair System presets,

Generated Multi Profile cards are now distributed in both X an Z axes,

Fix: Project Roots modifier (limit projection range, and fix the algorithm),

Added new strand generator: ‘Prism Mesh Guide’,
