I thought that this entire process was simply incredible when I was reading it. The process involves first using the pen tool to select the area of the face. After that it goes into the burn tool and also you’ll need some brushes, the link of which is posted in the tutorial. After all of that you can adjust the levels, curves and saturation. The next couple steps after that involve careful mask layers on the eyes and some parts of the face. After that you can load any image you’d like to be the connecting hair on the subject. Then adjust all the settings as before to get the image how you like. Apply some brush strokes and feathering and you’ll be done!
