While it might not seem like it, your hair is one of the most durable parts of your body. Even though it might seem flimsy or easily broken, hair is surprisingly resilient. Here are five interesting facts that you probably did not know about the human hair.
1. A single strand of hair can support up to 100 grams. Human hair is surprisingly strong and each strand can hold up to 100 grams of weight. That’s equal to about 40 pennies, 100 paper clips, or an iPod.
2. The average hair growth is around 1cm a month. It takes about two and a half months for the average person to grow an inch of hair, so think twice about whether you really want to cut your hair short. It could take the better part of a year to grow it out again.
3. Only 4% of the world’s population can boast natural red hair. We all knew that natural redheads are few and far between, but only about 4 percent of the world’s total population is a ginger. To put that in perspective, that’s about 288 million people out of over 7 billion people in the world.
4. Hair is the second fastest growing tissue in the body. The fastest growing tissue in the human body is bone marrow, but the second fastest growing tissue is hair. This is despite the fact that only about 80% of your body’s hair follicles are producing at any given time, and the average person loses between 50 and 100 hairs a day.
