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.
