If you have ever struggled to explain a haircut you want, this resource turns that uncertainty into a clear, visual result. With one photo and a brief quiz, the system studies your features, hair characteristics, and daily context, then delivers 10 matched cuts together with a detailed barber guide. Behind the result is not a simple filter, but a mathematical model with 50+ parameters and 3D head mapping, designed to show why a style works for you. Rather than applying a generic hairstyle overlay, it uses a mathematical approach with anatomical scanning to explain which details are emphasized. What you receive is a photorealistic lookbook, designed to avoid the flat look of toy-like filters and instead present a realistic rendering. It also includes a step-by-step haircut plan with parameters and notes for the barber, so the idea is easier to communicate in real life. The workflow stays lightweight: upload one selfie, wait roughly 30 seconds, and review the outcome without creating an account first. It is especially relevant when you want a haircut that matches your face, your hair, and your real life, not just a passing trend. https://hackaday.io/hairpicknet?saved=true
