Repairing details with a warped ellipse

So here I am looking at that alpha channel called final mask and you can see…that this entire region of hair is a mess.…I suppose things are okay in the center, but up at the top it's awfully scrappy…and down here at the bottom it doesn't even make sense.…So we are going to essentially re- create this section of the mask using…the Elliptical Marquee tool, but this area isn't really strictly speaking elliptical.…It's more of a shorter ellipse on the bottom than it is at the top.…So we are going to peel the ellipse into two pieces and stretch one of those…pieces independently.…

And here's how it works.…I am going to switch back to the RGB image so we can see the actual hair, and I…will go ahead and switch to the Elliptical Marquee tool, and then I am going to…position my cursor right about here.…Notice this would be the center point for any sort of ellipse we would…draw around this region.…So I am going to move my cursor directly in from that center point about yay far…from the match, and I'll press and hold the Alt key or the Option key on the Mac…
