4 UNTAMABLE FACTS ABOUT HUMAN HAIR

We all have hair. On our heads, faces, limbs, and in hidden places too, it’s a natural part of the human body. 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. Do you ever sometimes wonder why we have it, or what the point of it is? This furry extension to our body is more interesting than you may have ever thought!

What is the growth cycle of a follicle?

The first step is the growth of a hair. Around 85 to 90 percent of your follicles will be in the growth stage at the same time. Once the hair is fully grown, it enters the transition stage. This is where it has stopped growing but stays in the follicle until it is ready to fall out. A single hair can have an average life span of around 5 years before it falls out. Although the number of follicles stays the same throughout your life, as you get older your hair can naturally fall out. The average person loses between 50-100 strands of hair a day.

Human hair is both stretchy and strong

Although 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. 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. The average weight that a single strand of human hair can hold is 3 ounces (85 grams).

Information can be stored in our hair

As our hair grows it carries our biological make up with it. There are methods of testing that allow us to see the changes made to a piece of hair when it grows. 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.

We have 100,000 hairs, and counting…

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. You are born with an exact number of follicles on your body and you don’t grow more as you get older. The number of follicles you have is hereditary and can vary depending on your hair color.
