Both my brother and my father have it, have for years. But it's not until I didn't shave for a full week or so that I confirmed what I suspected ever since my brother decided to go for facial hear: I, too, am half redhead. The line starts about halfway down my ears, and everything south of that comes in ginger. I thought about keeping it going but it's summer and I'm not a huge fan of how long it takes Ben or I to grow a respectable beard so I shaved it all off today. And boy, does it look red once it's lying there in the sink.
