What Actually Happens When You Try "The Haircut Game"
I ran into this project about six months ago when someone on a design forum started complaining that every AI hair visualization tool they tried kept making people look like cartoon characters instead of actual humans. The concept sounds simple enough at first glance. It's supposed to let you upload a photo, pick a haircut style, and get back something that looks realistic. Most tools in this space fail hard on the first try. This one actually got close. The core of it uses a generative adversarial network paired with a segmentation model that separates your face from your existing hair, then synthesizes a new hairstyle based on your head geometry. Most people don't realize how much head geometry matters here. A side profile will look completely wrong if the model was only trained on front-facing images. I learned that the hard way.
The Haircut Game How Cuttingedge Technology Is Revolutionizing The Way We Get Haired
Here's the straightforward process. You download the tool, install it locally because the web version exists but throttles resolution severely. The local install runs on your GPU. If you don't have at least 8 gigabytes of VRAM you're going to have a bad time. Once installed, you take a well-lit front-facing photo. Not a selfie from below. Not a group shot. Just you, facing forward, even lighting, hair pulled back if it covers your forehead. The model needs to see your scalp line clearly. You select a style from the library, adjust the length slider, and run the generation. Wait time ranges from about 30 seconds to four minutes depending on your hardware and the output resolution you choose. The default is 512 by 512. I usually bump it to 1024 for anything I plan to show other people. One thing nobody mentions in the promotional material is the edge case where fine or thinning hair gets completely lost in the synthesis. The model tends to fill in texture that isn't there. I have a client who does beard and mustache work and needed to show a patient what a full fringe would look like with his thinning crown. The AI just painted on a full head of hair that had zero connection to his actual growth pattern. It looked like a helmet. I had to manually composite the result with a second pass using a different style preset and blend the transition zones in Photoshop. Took another twenty minutes but it was honest enough to show.
What the Tool Gets Wrong and Why It Matters
The biggest limitation is that it doesn't account for hair texture match. If you have tight curls and pick a style from the straight hair category, it will render that style as straight. It won't adapt the curl pattern. For barber consultations this is a real problem because a cut that looks good on straight hair looks completely different on coily textures. The developers are aware of this and have it on their roadmap but there's no ETA I can give you. Another issue is lighting mismatch. If your reference photo was taken indoors under warm light and you generate in what the model assumes is daylight, the color of the new hair will look off. The fix is to take your reference photo in neutral daylight whenever possible or use the built-in color correction pass before generating. It's not perfect but it gets you closer. There's also the matter of background. The segmentation model handles most backgrounds fine but if you have a busy background with similar colors to your hair the edges will fringe. I've seen this happen with dark brown hair against dark wood furniture. The workaround is to use a plain wall behind you or run the image through a basic background removal tool first. That adds a step but it saves you from fixing artificial halos later.

Performance Reality Check
This isn't a replacement for a stylist consultation. It's a conversation starter. I've used it with clients who couldn't articulate what they wanted and having a visual reference changed the entire direction of the cut. Sometimes it sends people in the wrong direction too, which is why I always follow up with a discussion about whether the generated look actually matches their daily routine and maintenance tolerance. The download link is on the official GitHub repository. There's a standalone executable for Windows and Linux. Mac support is experimental and honestly I wouldn't recommend it yet unless you know what you're doing. The community Discord has some walkthroughs that are more current than the README which hasn't been updated in three months. You'll also want to grab the style pack extension separately because the base install only includes about forty presets and the full library has over two hundred. Expect to spend an afternoon getting comfortable with it. The first five generations will probably disappoint you. By generation ten you'll start noticing what settings to tweak and when to just move on to a different approach entirely.
