Fine hair has the smallest circumference, coarse hair has the largest circumference, and medium hair is anywhere between the other two. Coarse hair has a more open cuticle than thin or medium hair causing it to be the most porous.
Leiotrichous hair (Asian) has the largest diameter, followed by cymotrichous hair (Indo-European), while ulotrichous hair (African) is generally finer than all the rest.
If you mean individual shafts of hair, East Asians have the broadest diameter, Europeans intermediate diameter, and sub-Saharan smallest diameter in cut cross-section. This is an average per forensic examiners since people have moved about the planet and intermarried.
Fine hair has the smallest diameter, whereas coarse hair has the largest diameter.
It is found that the average diameter of human hair can vary anywhere from 17 micrometers to 181 micrometers. So, taking an average value of its diameter as 50 micrometers, which can further be written as 50000 nanometers.
Asian and African hair have lower densities, with 175 hairs/cm2 and 161 hairs/cm2, respectively. Asian hair is the thickest, with a larger diameter of about 70 µm. Caucasian hair has an average diameter of 65 µm, and African hair is the finest, with a diameter of 55 µm.
Pubic hair shaft was thickest (respective male and female diameters were 100.21 μm, 88.40 μm) and eyebrow hair was thinnest (53.97 and 46.69-μm diameters in males and females, respectively).
Caucasian hair is oval. Its natural color ranges from light blonde to dark brown, with shapes that can be straight, curly or wavy. It has an average diameter of 0.07 mm. Caucasian Scandinavian hair is oval and very light blond with an average diameter of 0.07mm.
Asian hair is by far the thickest of all hair types – 80 - 120 µm in diameter. Because of its extra diameter, it is also the strongest, and most resistant to damage.
Root Diameter (R.D.) is the diameter of a circle around the bottom (root) of the gear tooth spaces. Base Circle is the circle from which the involute portion of the tooth profile is generated.
Mechanical properties vary among different ethnicities. Asian hair demonstrates the highest hardness and elastic modulus, followed by Caucasian and African hairs, respectively.
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. The hair was discovered on Muhammad's chin as part of his beard.

Final answer: Coarse hair has the largest diameter compared to fine and regular hair types.
Diversity of the hair diameter probably results from the fact that hair miniaturization does not equally affect all the hair follicles of the same area, resulting in the simultaneous presence of terminal, indeterminate, and miniaturized hairs. Indeterminate hairs (0.03-0.06 mm in diameter) are rare in the normal scalp.
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. Type 1B: Though still straight, this type has a medium (rather than fine) texture and a little more volume.
genes and me » hair curl. Human hair comes with all sorts of colors, textures and shapes. Notably, African hair is more coiled and dry; Asian hair is straighter and thicker; and Caucasian hair is somewhere in between with around 45% having straight hair, 40% having wavy hair, and 15% having curly hair.
A: In very general terms, the darker the hair, the thicker it is and the lower the density (hairs per area).
Coarse hair has a larger diameter and tends to be thicker and stronger than fine or medium hair. It is often more resistant to breakage but can be challenging to style due to its natural density. To care for coarse hair, focus on moisturizing and nourishing your strands.
H. Harris, publishing in the British Journal of Dermatology in 1947, wrote Native Americans have the least body hair, Han Chinese people and black people have little body hair, white people have more body hair than black people and Ainu have the most body hair.
African hair is seen to be much thicker and more dense meaning that the hair follicles are larger. Density represents the amount of hairs that grow from the head, with denser hair resulting from more hairs growing closer together from the scalp.
