Genetics and Biological Factors of Hair Color
- Approximately 2% of the world's population has naturally red hair
- Brown hair is the most common hair color worldwide, covering approximately 79% of the population
- People with blonde hair are more likely to have lighter eye colors, such as blue or green, with approximately 85% of blondes having blue or green eyes
- Gray hair typically appears in the elderly, but can start as early as the teenage years due to genetics
- The gene responsible for red hair is MC1R, which is recessive, meaning both parents must carry the gene for their child to have red hair
- Natural redheads tend to have a higher pain tolerance compared to other hair colors, according to some studies
- People with red hair produce more sweat in their hair follicles due to higher levels of a hormone called adrenaline
- In Japan, black hair is the dominant natural color, with over 99% of the population having black or very dark hair
- The genetic mutation for blonde hair is most common in Northern Europe, especially in Scandinavia and the Baltic region
- Gray or white hair typically results from the natural aging process due to the reduction of melanin production
- In the United States, about 16% of the population identifies as having a naturally red hair color
- The most common hair color for newborns is black or dark brown, which often lightens with age
- Natural black hair contains the highest amount of eumelanin, giving it its dark coloration
- People with black hair tend to have darker eyes as well, with over 70% of such individuals having brown eyes
- Light hair colors, such as blonde and light brown, are generally associated with higher levels of pheomelanin, a pigment responsible for reddish and yellowish hues
- The use of hair dyes can cause allergic reactions in about 1-5% of users, with sensitivity more common among those with lighter hair colors

Hair Characteristics, Health, and Aging
- The average person has about 100,000 to 150,000 hairs on their head, with variation depending on hair color
- Hair shedding is normal, with individuals losing about 50 to 100 hairs daily, regardless of hair color
- The hair growth cycle averages about 2-7 years for each strand, regardless of color, but the total amount of hair and rate of shedding can vary
