Rarest kind of redhead Having red hair and blue eyes is the rarest hair/eye color combination possible. The odds of a person having both of those recessive traits is around 0.17%. Instead, most redheads have brown, hazel or green eyes, according to Medical Daily.
The statistic is that red hair and blue eyes is the rarest combination. This article in MedicalXpress by a professor at University of Melbourne says, ``Around 17 per cent of people have blue eyes, and when combined with 1-2 per cent having red hair, the odds of having both traits are around 0.17 per cent.
The rarest shade of red hair is often considered to be ``auburn,'' which is a darker, richer shade of red with brown undertones. However, the most strikingly rare is ``ginger'' or ``fiery red,'' characterized by a bright, vibrant hue.
For a recessive trait to be expressed the individual must be pure breeding, hence two red heads can not produce any other colour in a child. If red hair is dominant, the chances are one in four that a child will NOT be a red head if mum and dad are both ginger nuts.
Women with red hair color exhibited higher sexual desire and sexual activity, a higher number of sexual partners of the preferred sex, earlier initiation of sexual life, and lower sexual dominance (and therefore higher sexual submissiveness).
Prior research has already put red-haired humans and mice into the spotlight, pointing out that they have a higher pain threshold. They also don't need as high of a dosage of pain-killing opioids, and they tend to require more anesthesia compared to people with non-red hair.

Having red hair and blue eyes is the rarest hair/eye color combination possible. The odds of a person having both of those recessive traits is around 0.17%. Instead, most redheads have brown, hazel or green eyes, according to Medical Daily.
The rarest eye colors are red and violet, which are primarily found in individuals with albinism. Excluding those affected by albinism, green and gray eyes are considered the most uncommon.
Type 1A: The rarest hair type, this one is very straight and fine with a “wispy” appearance. It's very difficult to get it to hold a curl.
Red is the rarest hair color, but to understand why that's the case, you need a basic grasp of the science.
Black hair or jet black hair is the darkest hair color. It has large amounts of eumelanin and is denser than other hair colors and is the commonly seen hair color in Asia and Africa due the fact that the people in these regions tend to have lower levels of tyrosinase in their bodies.
The most common eye color is brown. More than half of the world's population has brown eyes (some experts include amber as a shade of brown, too). A key reason is the range of shades that fall under this color. Brown eyes can range from light to dark.
That's why brown hair and brown eyes, which are both dominant, make up such a large percentage of hair-eye color combinations. But the red hair and blue eye combination is so unusual because it is the result of two different sets of DNA instructions, or mutations, happening in the same person, according to Elgar.
The Rarest Eye Shape
Almond, monolid, downturned, hooded—the list goes on. But the rarest one is up for debate. Beauty is subjective, and opinions can vary drastically.
How Rare Are Purple Eyes? People with purple eyes make up less than 1% of the world's population. This means purple, or violet, is truly one of the rarest eye colors across the globe. Finding accurate statistics for eye color is always a bit tricky because large-scale studies and data are few and far between.
One thing these survey results have in common is that light-colored eyes — green, gray, blue, and hazel — are named as the most attractive eye colors in the world.
Redheads have less hair and thicker strands than most people. On average, it's believed that those with red hair have 90,000 strands, while blondes have around 110,000 and brunettes have 140,000. Redheads are less likely to go grey.
Red headed women reported more frequent diagnoses of cervical uterine cancer, cervical uterine precancerosis, ovarian cancer and other cancer. Both male and female redheads reported more frequent diagnoses of colorectal cancer.
One of the many facts about redheads is that their hair will never turn grey. The pigment in their hair that causes it to be red will just fade over time, causing their hair to turn blonde or white, but never grey.
