The average weight that a single strand of human hair can hold is 3 ounces (85 grams). It is said that a whole head of hair combined could support the weight of around 12,345 to 18,518 pounds (5,600 to 8,400 kilograms), or the equivalent to the weight of two elephants. Human hair is both stretchy and strong.Īlthough human hair is not as strong as steel, it is so strong that it could hold more weight than a piece of copper wire the same length and width as a single hair. ![]() The chemical particles remain part of that exact piece of hair forever. Once the hair starts to grow up and out the body, it carries these chemical particles with it as they are part of the strand of hair when it formed. The chemical particles remain where they were deposited in the follicle and as the hair strand starts to grow, the particles deposit into the cortex of the hair strand itself. When we consume something it is broken down into particles, certain elements enter the blood stream.Īs the particles travel around our bodies they can be deposited into the follicle of a growing hair. Here are the stages of how your hair stores information of what you have ingested. We can see from hair samples if certain drugs were taken, if there was a lack of vitamins and nutrients at a point of time in someone’s diet. However in hair these changes aren’t visible to the naked eye, but there are methods of testing that allow us to see the changes made to a piece of hair when it grows. This has been used for many years as a way to see if someone is malnourished or is lacking something in their diet. Now you might think this sounds crazy, our hair doesn’t have a hard drive or a “cloud” to store things, so how can this be true?Īs our hair grows it carries our biological make up with it.įor example when our nails grow and we see white marks, they are indications of a lack of nutrients or vitamins in the body at the time that part of the nail was formed. This could be in the form of hair removal, taking certain medication for illnesses like cancer or even through stress. There are other things that can affect the number of hairs you have on your body, but most of these are by human intervention. People with naturally blonde hair tend to have more follicles, with an estimate of 150,000 hairs on their head, whilst people born with naturally red hair tend to have only around 90,000 follicles. ![]() ![]() The number of follicles you have is hereditary and can vary depending on your hair color. You are born with an exact number of follicles on your body and you don’t grow more as you get older. Not only this but we also have up to 150,000 hair follicles just on our head and around 5 million over our entire body. This furry extension to our body is more interesting than you may have ever thought! We have 100,000 hairs, and counting…ĭid you know that the average adult human can have around 100,000 hairs? Over time as we have evolved, hair has transitioned from being an important part of our survival by keeping us warm, to becoming a tool that we use to express our personality.ĭo you ever sometimes wonder why we have it, or what the point of it is? On our heads, faces, limbs, and in hidden places too, it’s a natural part of the human body.
