Hey Peerlist community! 👋I'm Kai, an indie developer passionate about generative AI. Today I'm excited to share a side project I've been refining: AI Hair Studio.<h3>🤔 The Problem</h3>We've all been there: staring at the mirror, wondering "Is my face Oval or Square?" or "Will bangs look good on me?" Most online guides are vague ("if your jaw is wide..."), and trying a new haircut is a high-risk gamble.<h3>💡 The Solution</h3>I built a 2-step AI tool to solve this:Step 1: The Face Shape Detector (Free Tool) Instead of guessing, I use computer vision (facial landmarks) to calculate your exact facial ratios:<ul><li>Three Courts: Vertical balance (Forehead vs. Nose vs. Chin).</li><li>Five Eyes: Horizontal width balance.</li><li>Face Contour: Jawline angle and cheekbone width.</li></ul>You get a detailed report telling you if you're a Diamond, Heart, or Oval shape, with visualizations of your metrics.Step 2: Virtual Hairstyle Try-On Once you know your shape, you can visualize the result. My main app allows you to:<ul><li>Upload a selfie.</li><li>Pick a hairstyle (e.g., "Curtain Bangs", "Buzz Cut").</li><li>Use Generative AI to realistically render that hair on your head.</li></ul><h3>🛠️ Tech Stack</h3><ul><li>Frontend: Vue 3 + Tailwind CSS (hosted on Firebase).</li><li>AI/Backend: Python (Flask) with Landmark Detection models + Generative Diffusion models for the hair swap.</li><li>Deployment: Google Cloud Run.</li></ul><h3>✨ Try it out</h3>I'd love to get your feedback on the accuracy of the detection and the quality of the hairstyle generation!<ul><li>Detect Face Shape (Free): <a target="_blank" rel="noopener noreferrer" class="break-all link-break text-gray-500 hover:underline" href="https://www.aihair.studio/faceshape">https://www.aihair.studio/faceshape</a></li><li>Main App: <a target="_blank" rel="noopener noreferrer" class="break-all link-break text-gray-500 hover:underline" href="https://www.aihair.studio">https://www.aihair.studio</a></li></ul>Let me know what you think! 💇♂️💇♀️
