Actually the problem with Red heads isn't that they don't breed enough, but that they only come naturally from Ireland. Apparently if you go far enough back any red heads ansestory, you find an Irishman there somewhere.
And since both parents must have the gene for the child to have red hair, it's being produced less and less.
So the obvious solution is for the Irish to mate with anything that walks!
Then, it'll be in everybody's genes and more people with be born with the Red.
Unfortunately, they haven't discovered why Red heads are always more stubborn or how to breed that out.
And Windwalker, my hair is the same way. It's naturally a brown mess, but it's got natural red and blonde highlights, with strawberry lowlights...
I've had a few people suddenly stop talking and stare at me for a few minutes when I'm on the bus or in a car... My hair has suddenly gone bright blonde. then brown and then flaring red in just a matter of seconds... apparently it really throws people off.
Mind you, I do tend to die my hair when given the chance... I die it Red Auburn... When asked why I do it, if I already have red hair, I always answer the same... "Yes, but not enough!".
