Red hair is rare because the trait is a recessive gene when paired up with other types of hair. In most cases both sides of the parents have to have that gene to even make it possible.
Many people have the trait for red hair, but it takes 2 people with the trait to produce an offspring with red hair, making it twice as difficult. That is why red hair is not typical.
This could be an extremely difficult question if your talking in general since people dye their hair all the time (Mine's dyed right now actually) but if you're talking about natural hair color then I believe that would be red hair. I'm not really sure why, it's a matter of genes I guess.

But It's Rare To Keep To Pure Blonde For Over 10 Years.But Red Is A Different Story. It Is Rare To Produce A Child When Both Parents Aren't Red Haired. Although - It Is More Common To Have A Child When Both Parents Are Red Haired. Did You Know About 1-4% Of The World Are Red Haired And Pure Blondes Are 2%? But This Is A VERY Hard Question To Solve... Personally I Think Pure Blondes Are The Rarest!
