Sea otters have the thickest fur of any animal.
Their fur contains between 600,000 to 1,000,000 hair follicles per square inch. Unlike most other marine mammals, otters lack a blubber layer. Instead, they depend on their dense, water-resistant fur to provide insulation.
Caucasians have the highest hair density among the ethnicities studied. Black people have the lowest. Asian people have hair density that falls somewhere in between.
With a million hairs per square inch, the hairiest animal in the world is the sea otter. An adult sea otter can have over a billion hairs.
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.
Yes, only 11% of the population have curly hair.
Curly hair is not certain to a race or ethnicity, it appears all over the world in many forms. White, brown, black and everything inbetween! There is also a scale on which curly hair is classified (2a-4c).
The luxurious locks of Xie Qiuping (China) achieved the longest hair in the world on a female with a length of 5.62 m (18 ft 5 in), as verified on 8 May 2004. She started growing her hair in 1973, when she was just 13 years old.
While ladder-length hair is out of reach for most people, there's no set point at which all hair stops growing. Instead, hair growth is the complex product of genetics, health, care, and even seasonal changes.
Long Hair Can Make You Sick
More surface area means more places for viruses, pollution, and bacteria to settle. And when you consider that hair often sits near mouth level of others, it is no surprise that it can act like a home-grown mop for attracting disease carrying droplets.
Geneticists at the University of Tokyo and several other institutions in Japan, Thailand, and Indonesia have now used the HapMap to explore why Japanese and Chinese people have thick hair: The cross-sectional area of East Asian hair fibers averages about 30% larger than that of Africans and 50% larger than that of ...
(Another fun fact: While men experience their thickest hair in their 20s, many women experience their thickest head of hair in this decade.)
Thicker strands of hair are more likely to have a defect, making them more prone to breakage, the researchers believe. Lustrous, thick hair may be desirable but it is not necessarily the strongest. Scientists said thin hair tends to be stronger than thicker locks, after looking at the way they break.
Many Asians have naturally straight hair, but there is a significant group of us who do have naturally curly or wavy hair! However, because it's the norm to see straight and sleek hair, curly haired boys and girls tend to think that their hair is some kind of unruly straight hair that isn't behaving.
Hair type 1A is super-straight. It doesn't even hold a curl! 1A is the rarest hair type. It is usually found on people of Asian descent.
Most people of East Asian descent have thick, straight hair. This corresponds with a SNP (rs3827760) in the EDAR gene which is involved in hair follicle development. The ancestral allele of this SNP is the A-allele. The G-allele is the newly derived allele that leads to the thick, straight hair.
One popular myth is that hair loss in men is passed down from the mother's side of the family while hair loss in women is passed down from the father's side; however, the truth is that the genes for hair loss and hair loss itself are actually passed down from both sides of the family.
And while the results did vary, in the end we found that 58% of the fellas agreed that curlier is sexier.
A single hair has a normal life between 2 and 7 years. That hair then falls out and is replaced with a new hair. How much hair you have on your body and head is also determined by your genes. Nearly everyone has some hair loss with aging.
We actually have the same density of body hair as other apes of our size, but ours is largely fine and colourless rather than thick and dark. We are coated with a layer of short, fine hair, known technically as vellus hair and colloquially as peach fuzz.
But the evolutionary reasons why hairiness varies with ethnicity are unclear. Caucasian people are generally hairier than the Japanese, for example, even though testosterone levels are the same. The difference seems to be in how sensitive the hair follicles are to those testosterone levels.
