Red hair dye looks fake; I don't know why people use it.
Blondes require two recessive genes, too.
The ancient Scythians had red hair, a long ways from Scotland. Scotland and Ireland do produce a lot of redheads. Maybe they will save the genes for it.
We aren't going to die out. The gene for red hair is tied to the gene for reproducing like rabbits on caffine.

I would be pretty upset if redheaded women were to become a thing of the past. I have quite a fondness and attraction towards them...;)
