Red hair. Red hair ranges from light strawberry blond shades to
Natural red hair is the rarest hair color in the world, only occurring in 1 to 2% of the global population.
Quercitron yellow takes the crown as the most forgotten color. This is partly due to its two confusing names—what we now know as quercitron yellow used to be known simply as quercitron or more commonly as “Dutch Pink.” Umm, what?
Interestingly, natural blondes are increasingly rare, constituting only about 2% of the global population, according to the WHO. So why the comparative scarcity of towheads? The alleles for light hair are recessive genetic traits.
Black hair is the darkest and most common of all human hair colors globally, due to large populations with this trait. This hair type contains a much more dense quantity of eumelanin pigmentation in comparison to other hair colors, such as brown, blonde and red.
The level system is made up of 10 numbers which help determine the depth level of your natural hair. 1 is black, 5 is light brown, 6 is dark blonde, 7 is blonde and 10 is the lightest blonde.
According to Curlkeeper, less than 20% of people have curly hair, making it a rare hair type. However, curly hair comes in all kinds of different styles starting with super coiled curls to slightly wavy. Curly hair requires work to maintain and take care of it, making it hard for some to stick to the routine.
Age: With aging, the activity of melanocytes, the cells that produce melanin, changes. In childhood, these cells might produce less melanin, resulting in blonde hair. However, as one grows older, the melanocytes can become more active, leading to the production of more melanin and, consequently, darker hair.
Gray eyes and green eyes are considered to be the rarest eye colors. Your eye color is determined by multiple combinations of genes that produce and distribute pigments. Some rare conditions can affect your eye color as well. Some people are born with heterochromia or different colored eyes.
1a hair type is the finest and straightest subtype of Type 1 hair. This hair type is generally gleaming and tends to be very smooth to the touch. However, it can also be quite delicate and prone to breakage due to its thinness. It is also the most challenging type to create volume or style due to its lack of texture.
Despite its popularity, strawberry blonde hair only occurs naturally in between 1 and 2 percent of the world's total population — which means it takes hair color and technique to make it happen for the rest of us. In fact, it's a hue that's been rare yet in demand for centuries.
A general observation across experiments was that straight hair was perceived as younger, healthier, and more attractive than wavy hair and darker shades (medium copper and brown) were perceived more positively than blonde hair.
According to an article by evolutionary biology professor Mark Elgar, PhD, of the University of Melbourne, blue-eyed redheads are the absolute rarest, with 0.17% of the population having that combination of hair and eye color. So if that describes you, you're most likely one in a million—or more!
Coily hair is often referred to as afro or kinky hair, as well as type 4. Coily hair can consist of very tight corkscrews or a 'Z' shaped pattern that starts right from the root. Due to its tight curls, this curly hair type often appears shorter than it actually is - this is referred to as shrinkage.
Nature's Rarest Palette: Red Hair Standing at the apex of rarity, natural red hair occurs in just 1-2% of the global population. This striking shade results from a specific genetic variant of the MC1R gene, requiring both parents to pass on the recessive trait.
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.
In 2025, hair colour trends are shifting and clients are moving away from icy platinum tones and embracing warmer shades like butter blonde, beige blonde, honey blond and strawberry blonde. Bright blonde is also a versatile option achieved through finely woven highlights for a natural look.
Hair morphology is one of the more conspicuous features of human variation and is particularly diverse among people of European ancestry, for which around 45% of individuals have straight hair, 40% have wavy hair, and 15% have curly hair.
The standard deviation (±) and range are expressed for each of the averages. Straight hair was the most predominant hair type − 84% (21/25) in men and 64% (16/25) in women - followed by wavy hair − 12% (3/25) and 28% (7/25), respectively. Curly hair was present in 4% (1/25) and 8% (2/25) of men and women, respectively.
Representing only about 2% of the global population, natural blondes are relatively rare, making this hair colour one of the less common natural shades.
What is 2 Hair Color? Unlike 1 and 1B, 2 hair color is a shade of dark brown. While it looks black from a distance, up close, you can see the subtle brown hue. It is one of the most natural-looking dark shades and has a warmth not found in true black shades.
The Letters like N mean natural, A for Ash , V for violet, . So 5N is 5 natural . Each hair coloring company has a hotline might need to call because I'm not sure about just "5" being neutral also. For myself I always use the "neutrals " because it looks better .
