Guide · AI head swap with hair

AI head swap with hair: swap the whole head, not just the face.

A face swap pastes a face and keeps the old hair, head shape and ears, which is why it so often looks wrong. A head swap moves the whole head, hair included. Cubric Studio's Head Swap Flow does it on your own PC.

Short answer

For a face swap with hair, use a head swap. Cubric Studio (free) plus its Head Swap Flow (sold separately on Gumroad) swaps the whole head, hair included, from one picture onto another, locally.

Face swap vs head swap with hair

Face swap tools replace the face inside the old outline. The hairline, the hair, the ears and the shape of the head stay from the original photo, so the person never quite looks like themselves. People search "face swap with hair" because that is the part that is missing.

A head swap takes the whole head from your reference picture (face, hair and all) and places it on the body in your base picture, then blends the neck and lighting so the seam disappears.

How the Head Swap Flow works

Pick the base picture, the one whose body and scene you keep.
Pick the reference picture, the one whose head you want.
Draw a box round each head and run.

It runs on FLUX.2 Klein 9B with a head-swap LoRA, on your own graphics card. The Flow carries its own tuned settings, and the finished picture lands in your project like any other card, ready to edit further.

What you need

Cubric Studio, free and open source.
The Head Swap Flow, a Flow package sold on Gumroad. Drop it on the Flow Library and it installs its own models.
A graphics card with about 16GB of video memory (FLUX.2 Klein 9B peaks near 15GB), or a rented RunPod graphics card from inside the app.

FLUX.2 Klein 9B has a non-commercial model licence that you confirm before it downloads; the pictures you make stay commercially usable.

Swap only heads you have permission to use

Use your own photos, or photos of people who agreed. Putting someone's head on another body without their consent can be illegal, and sexual pictures of a real person without consent are illegal in many places.
