I think red heads are very attractive especially for women. 
Only 1-2% of people in the world have red hair...so the women with red hair are few and far between!
That's very true, especially for the attractive one :/
What hue of red hair do you like?  It varies from deep burgundy to a burn orange/strawberry colour?
I like strawberry blonde, but also deep burgundy, really depends on if she has an attractive face.
You'll have to go to Germany or Celtic nations, thats where you'll find more red heads!
Why does it originate from there ? Is it because of genetics ?
Yes because of genetics,  people from those countries are more prone to receiving two recessive alleles on chromosome 16!
