i don't think there's many pure bred people left, I've got Irish, Sioux Indian, German, English... The fine red facial hair just doesn't come in that well, and when it finally does it's patchy and kinda does its own thing...
Mine is similar when it starts out. Fairly similar background too except it isn't Sioux. It starts off fine red hair then ends up turning into bushy, ginger goodness. The thinner/patchy areas end up filling in. Of course, I'm getting some coarse white hairs mixed in these days.
