Build Your Own AI Hairstyle Try-On App (2026)

If you’re searching for a hairstyle try-on app’s GitHub source code, you probably want something you can shape to fit your own needs — your styles, your colors, your look. This guide shows you how to build your own version in Auto instead of forking someone else’s repo.

Why build instead of clone?

Searching “ai hairstyle changer github” turns up a handful of repos and demos. Most are half-maintained, wired to a “hair changer api” you have to key in yourself, and styled for someone else’s taste. You can build a hairstyle changer with the Replicate API and stitch the front end together — but that’s a weekend of setup before you try on a single haircut.

Auto skips that. It’s camera-first: you describe the app you want, snap or upload a photo, and Auto builds you a personal mini-app — a Frame — around it. No code, no app store, no generic app that almost fits. People have already built ones like Hairstyle Studio, which is proof the concept works — but the point is that you make yours.

Building it in Auto

1. Open Auto and describe what you want: an app that swaps the hair in a selfie for different styles, with controls for color and length.
2. Upload a photo of yourself (or whoever’s trying looks on).
3. Ask for the specific styles you care about — the cuts your people actually want, not a fixed top-15 list.
4. Refine it: change the accent color, add hair colors, fix any layout that feels off. You just say what you want and Auto adjusts.

The whole loop takes minutes, and the result is tuned to you.

How someone built theirs

One Auto user built a real hairstyle studio, and their prompt history is a good template.

They started broad: an app to replace hair from a selfie with the top male and female styles, then swipe through a look book — each hairstyle with a chosen style, color, and length (S/M/L).

From there they got specific. They asked for a comb emoji on the Afro style and a different icon for the slick-back. When a tapped photo in the look book grew but got clipped by its container instead of going full screen, they flagged it and Auto fixed it. They recolored the whole app pink. They caught a cropped selection ring on the color picker — not enough padding — and had it fixed while adding salt-and-pepper, grey, and white to the color options.

Later they migrated the project to Auto’s current template, hit a build validation error (a cloud function missing from the manifest), pasted the error back in, and had Auto register it. A final “update to the latest components” and it was done. Every step was plain description — no code.

FAQ

Do I need the GitHub source code to build this? No. GitHub repos and the Replicate API are one route, but Auto builds the whole Frame from your description — no cloning or API keys.

Can I use my own hairstyles and colors? Yes. That’s the point — ask for the exact cuts, lengths, and colors you want, and change them anytime.

How long does it take? Minutes for a working version. Refinements are just more prompts.
