AI Hairstyle Preview Generator with OpenAI & LINE Sharing

This workflow enables salons and creative teams to generate customized hairstyle previews effortlessly. Users submit an image and text instructions via an n8n Form trigger. The system uses OpenAI's Image Edit API to modify only the hairstyle while preserving the original face and identity, ensuring realistic and consistent results.

The edited image is automatically uploaded to Cloudinary for secure, public URL generation. It then pushes the final preview directly to a designated LINE group using the Push API—no reply tokens needed. Group ID is stored securely in n8n's Data Store after initial setup, preventing mis-sends.

Benefits include rapid prototyping for client consultations, team collaboration without manual sharing, and scalability for high-volume requests. Ideal for beauty salons, barbershops, or marketing teams showcasing hair trends. Saves hours on Photoshop edits and streamlines social proof sharing.
