I'm thinking about dying my hair, but I'm not sure which color. What do you think about red?
Red hair is really rare! only 1 to 2 percent of the world population has red hair.
Really?! But which shade of red? Like fire engine red, or orangey?
Well it mostly comes from people with western european ancestry. There are a ton of different shades!
I've seen a lot of Irish people with red hair before. I wonder if red hair is more common in Ireland than anywhere else
It is! It is characterized by high levels of the reddish pigment pheomelanin which is more prevalent in Ireland.
Does the weather have anything to do with the red hair in Ireland or is it based on their ancestors?
It is mostly just regional, it is associated with fairer skin color and lighter eye colors as well.
