Hello, I'm an expert in genetics and cultural studies. When it comes to the question of whether red hair is Scottish or Irish, it's important to understand that this trait is not exclusive to either nation, but is more prevalent in certain populations.

Red hair is caused by a genetic variant that affects the production of the pigment melanin, which gives color to our hair, skin, and eyes. The gene responsible for this trait is the MC1R gene. Red hair is most commonly found in people of Northwestern European descent, and it is indeed more frequent in Scotland and Ireland than in many other places. However, it is not accurate to say that red hair "belongs" to either Scottish or Irish people, as it can be found in various populations around the world, albeit less frequently.

The highest concentrations of red hair are found in the Orkney Islands, which are under Scottish jurisdiction, and it is also quite common in Ireland. However, the trait is also present in other parts of the UK, such as Wales and England, as well as in other European countries like Norway and the Netherlands.

In conclusion, while red hair is more common in Scotland and Ireland, it is not exclusive to these regions. It is a genetic trait that can be found in various populations, although at different frequencies.
