The thickest strand of human hair is 772 micrometres (0.03 inches) and was plucked from the beard of Muhammad Umair Khan (Pakistan), in Lahore, Punjab, Pakistan, as verified on 3 March 2021.
It has been reported that Asian hair is generally straight and is the thickest, while its cross-section is the most round-shaped among these three. Caucasian hair is generally straight or wavy and is the thinnest, while its cross-section is relatively elliptic.
More than 90% of Han Chinese, 70% of Japanese and Thai people, and 60% to 90% of Native Americans carry the “thick hair" version of the gene. Meanwhile it's almost nonexistent in people of African and European descent.
Sweden. Livings standards, healthy lifestyles, geography, and diet are the primary factors why people in Sweden have the healthiest and beautiful hair.
Caucasian hair usually appears thicker since it is more difficult to see through the scalp than other ethnic hair types. However, Asian hair is the thickest and coarsest hair of any ethnic group.
The reason Asian hair tends to be thicker is that it has around 10 layers of cuticles. Cuticles are the small areas around the inner protein structure of your hair–they are there to protect those proteins.

Czech Republic - 42.79% of Prague men balding or bald (takes the #1 spot) Spain - 43.60% men bald or balding. Germany - 41.24% men bald or balding.
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.
It is not always true that Asians have thicker hair. Although it may appear thicker due to its dark hue, it is not necessarily thicker. Asians often have quite fine, thin and dry hair. This occurs when individuals shampoo their hair too frequently or when they do not take appropriate care of the hair itself.
Genetic studies found that hair thickness in Asian populations is linked to genetic variations. Fujimoto et al observed a correlation between a nonsynonymous single nucleotide polymorphism (SNP) in ectodysplasin A receptor (EDAR) gene and hair thickness in Asians in a genome-wide analysis.
“It is usually dark brown or black, has the thickest diameter of any of the ethnic groups and, moreover, is one of the strongest types of hair, with a capacity to grow to a greater length than that of other races - often over 40 inches,” he writes.
Asian hair the most dominant hair type in the world out speeds the rest with a growth rate of 1.3cm per month, and despite an estimated 80,000 to 140,000 scalp hairs, it usually has the least density.
The density of Caucasian hair is the highest of the three ethnic groups, so it is the most dense.
Individuals of African ancestry, for example, are more likely to have curly hair due to the oval shape of their hair follicles. Additionally, the Keratin Associated Protein (KAP) cluster genes, responsible for the structure of keratin fibers, have been found to have variations in many African populations.
We believe one of the reasons is that super-straight hair — also known as type 1a hair — is so rare. In fact, it's the rarest hair type. Only 2% of the world's population has 1a hair. It's mostly found in people of Asian descent.
Hair type 1A is super-straight. It doesn't even hold a curl! 1A is the rarest hair type.
Chinese and Japanese men have the lowest rates. For some unknown reason, this form of hair loss is does not occur among Native Americans. Male pattern baldness runs in the family. If your grandfather, father or brothers went bald early, the chances are that you will too.
While Asian hair tends to be more coarse than other types, those of Asian descent can still experience thinning hair. Androgenetic alopecia and female pattern hair loss are common types of hair loss among Asian populations.

Genetic factors appear to play a major role in determining hair texture—straight, wavy, or curly—and the thickness of individual strands of hair. Studies suggest that different genes influence hair texture and thickness in people of different ethnic backgrounds.
First things first, thick hair doesn't necessarily mean healthy hair. Some peeps desire thick hair because they associate it with fuller, healthier-looking hair. Many folks try to avoid thinner hair because of its perceived links to unhealthy hair and hair loss.
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.
