As a subject matter expert in the field of human anatomy and physiology, I can provide you with detailed information regarding the size of human hair. Human hair is a fascinating structure that serves multiple functions, from providing warmth and protection to being a significant aspect of personal appearance and identity. The size of a human hair, particularly its diameter, varies among individuals and can be influenced by factors such as ethnicity, age, and overall health.
To begin with, let's discuss the unit of measurement that is often used to describe the fineness of hair and other small structures: the micron. A micron, also known as a micrometer, is a unit of length equal to one millionth of a meter. This is a very small measurement, roughly equivalent to 0.00004 inches. It is a standard unit for expressing the size of microscopic objects, including human hair.
When we talk about the size of human hair, we are typically referring to its diameter. On average, a single strand of human hair has a diameter that ranges from about 17 to 181 microns. However, this is a general range and the actual size can vary significantly. For instance, the hair of individuals with African descent tends to be curlier and has a flattened, ribbon-like shape, which can affect the measurement of its diameter. In contrast, hair from individuals of Asian descent is often straighter and rounder, with a more consistent diameter.
The average diameter of a human hair is often cited as being around 75 microns, but this is a generalization and the actual size can be influenced by various factors. For example, the hair on different parts of the body can vary in thickness. Head hair is typically thicker than body hair, which is usually finer and more delicate.
Additionally, hair thickness can change over a person's lifetime. As people age, their hair follicles may produce thinner and finer hair, which can make the hair appear more delicate and less dense. Nutritional deficiencies, hormonal changes, and certain medical conditions can also impact the thickness and health of hair.
It's also important to note that the thickness of hair is not the only factor that contributes to its overall appearance and texture. The shape of the hair shaft, whether it is round, oval, or irregular, can affect how the hair looks and behaves. Round hair shafts are typically associated with thicker, more voluminous hair, while flat or irregular shapes can lead to thinner, less full hair.
In conclusion, while the average diameter of a human hair is often cited as being around 75 microns, it is essential to recognize that this is a general figure and the actual size can vary widely among individuals and even within an individual's head. Understanding the factors that influence hair thickness and the importance of hair health can help individuals take better care of their hair and maintain its beauty and functionality.

A "micron" is an abbreviated term for "micrometer", or a millionth of a meter (1/1,000,000 meters). This is about .00004 inches. For Size comparison, a human red blood cell is about 5 microns across. A human hair is about 75 microns across (depending on the person).
