Diameter of human hair. A single bacterium is about 1000 nanometers long. Primarily our genetic is the most factor decides the average thickness of human hair whether we have thick or thin hair. Flaxen hair is the finest from 11500 to 1500 of an inch in diameter and black hair is the coarsest from 1450 to 1140 of an inch.
The diameter of human hair on the scalp varies between 004mm and 025mm. Black hair is the coarsest or thickest. In my research I have found the diameter of human hair to range from 17 to 181 µm millionths of a meter.
A strand of hair is about 80000 to 100000 nanometers wide. A strand of human DNA is 25 nanometers in diameter. The hair thickness is determined by the size of the hair follicles whereas the size of the hair follicles is mainly determined by their number on the scalp.
With diameter less than 25μmjust 3 percent the diameter of a human hair. Black hair is the coarsest or thickest. Determination of diameter of human hair by laser diffraction method.
This hair type grows diagonally and at a rate of about 12 centimeters per month. This measurement is not precise because human hair varies in diameter ranging anywhere from 17 μm to 181 μm. Its color can vary from blond to dark brown.

At William Collier Design we specialize in non-surgical hair replacement helping Seattle WA area clients overcome their hair loss and look in the mirror with confidence. A human hair is approximately 80000- 100000 nanometers wide A single gold atom is about a third of a nanometer in diameter On a comparative scale if the diameter of a marble was one nanometer then diameter of the Earth would be about one meter One nanometer is about as long as your fingernail grows in one second. Individual strands of hair range in thickness from 11500 to 1500 of an inch in diameter depending on the properties of the hair in question.
Applied mathematics expert Stefan Robert explains that you can calculate the diameter of a human hair by using an infered beam and simple measurements. In addition to contributing to risk of lung disease PM 25 particles pass even deeper into the lungs alveoli the blood vessel-covered air sacs in which the bloodstream exchanges oxygen and carbon dioxide. The micron is symbolized by the Greek lowercase letter mu The abbreviation micron was initially used to distinguish the units of a tool used to measure small distances also called a micrometer.
Our tax-ID number is 91-0282060 and donations are tax-deductible to the extent allowed by law. Another factor is that the closer to the root of the hair the thicker a strand of hair would be. One nominal value often chosen is 75 μm but this like other measures based upon such highly variable natural objects including the barleycorn is subject to a fair degree of imprecision.
The diameter of human hair varies from 0017 to 018 millimeters 000067 to 000709 in. Europeans consider hair with a diameter of 004 to 006 mm as thin hair with a diameter between 006 and 008 mm as average and hair with a diameter between 008 and 01 mm as thick. Caucasian hair strands are oval in shape.
By comparison with European hair Asian hair is significantly thicker. The average diameter of human hair is roughly 00035 inches in diameter which is equivalent to 75 microns. Seattle Humane is a 501c3 organization.
Once PM 25 particles enter the bloodstream via. Individual strands of hair range in thickness from 11500 to 1500 of an inch in diameter depending on the properties of the hair in question. Typically blond hair is thinnest since it usually does not have a middle layer like dark hair does.
