How well does it work with hair? Hair is notoriously hard to select well in Photoshop for most retouchers, so it would be amazing if the automation somehow became better than professional humans doing the editing. There are a ton of manual techniques out there for extraction, none of them work incredibly well out of the box depending on the background you're working with.

I found this class on hair retouching to be great btw, goes pretty in depth on the latest techniques used in commercial-grade work: https://proedu.com/collections/available-tutorials/products/...
