Hairstyle Changer
Try any haircut or hair color before you commit. Upload a selfie and use the hairstyle changer workflow to a variety of hair options.
简介
Hairstyle Changer is a ComfyUI workflow that lets you preview different haircuts and hair colors on a selfie before you commit. It starts with LoadImage to bring in your photo, then routes your style choices through ComfySwitchNode and preset strings defined in PrimitiveStringMultiline. Those choices are combined with StringConcatenate and, when needed, pulled from a structured presets block via JsonExtractString. The edited result is displayed in PreviewAny and saved through SaveImage.
At the core is a custom processing node (id: d4c06663-cb1a-4a41-a36b-f09c93e55e7e) that applies the hairstyle/color change using the inputs prepared upstream. CustomCombo is used to package the image and text parameters into a clean input for that node. This parameterized design makes it easy to A/B test looks simply by flipping the ComfySwitchNode or tweaking the preset strings—keeping your original photo intact while focusing changes on hair appearance.

# run() also passes api_key to the partner nodes in this workflow.
job = client.run(workflow, api_key=api_key)常见问答
A front-facing photo with even lighting, minimal shadows, and hair clearly visible. Avoid hats, heavy hair accessories, or obstructions. A neutral background helps the processor focus on hair.
It is configured to target hair appearance via the custom processor (node id d4c06663-cb1a-4a41-a36b-f09c93e55e7e) and its text parameters. Minor spill to nearby regions can occur; if you see drift, try a tighter crop around the head, reduce extreme style changes in the preset text, and rerun.
Edit PrimitiveStringMultiline to include new preset entries (e.g., keys like "copper_lob" or "icy_blonde"). Use JsonExtractString to pull those entries, and ensure your ComfySwitchNode points to the correct keys. StringConcatenate will assemble the final parameter string for the processor.
Install the extension that provides the custom node with id d4c06663-cb1a-4a41-a36b-f09c93e55e7e and restart ComfyUI. Check the ComfyUI console/log for the exact repository or package name if it’s indicated by your setup.
