Irish Red Hair. Red hair, especially pale red hair, is often regarded as the characteristic feature of the people of Ireland. Today, Irish red hair is one of the most popular and desirable hair color for women. The most commonly associated myth is that people with red hair have a fiery temperament. For example, Achilles, character of Homer's Iliiad, was known for strength and temperament is described as having red hair.
If you have Scottish and/or Irish ancestry AND red hair, you probably also have VIKING ancestry, according to a new study. The director for Nordic Studies at the University of the Highlands and Islands says red hair is modern evidence of the influence of the ancient Vikings in Celtic lands.
