Methinks some photoshopping has been done on the first one. The head is just a smidge too small, the skin tone is just a smidge off when you compare the face to the chest, and there's a hint of blurring around the hair, most noticeably at the top, where the photoshopper tried to obscure the edges of the overlay. (I've done this kind of thing myself, lol).
He doesn't need it. The one that's natural actually looks better to me!
