Perhaps six months ago, somebody posted a video tutorial for how to insert a woman with complicated hair into another image (it was an interior room of a house). Rather than selecting and extracting the woman and her hair, he placed the entire photo of her---including the background---onto the new image then cleverly made the unwanted background disappear using (I think) blend modes, leaving a perfect selection of her hair. The video was narrated and may have had music. That's about as much of it as I can remember. I tried searching this site for various keywords such as 'hair' and 'selections', and I also searched the Tutorial forum, but I can't find it. Any help please?
