What is a strand of hair?

According to much research and observation, hair is a protein filament that grows from follicles found in the dermis. A long time ago, hair is considered to be one of the decisive factors in the beauty of humans. Having a healthy and beautiful hair has, for a long time, become the dream of many people. There are many different opinions on the definition of a strand of hair. Some people consider that the noun strand refers to things that are long and thin. Therefore, a single hair or human is known as a strand of hair. Other people believe that a strand of your hair simply describes a single hair. In our article, we recommend that you should understand this concept as a threadlike piece of our natural hair, also called a single strand of hair.

What constitutes a strand of hair?

Each hair strand is made of three main parts including medulla, cortex and cuticle. In those three parts, the medulla is an open and unstructured region. The cortex, which is the primary source of mechanical strength and water uptake, is highly structured and organized. The third part, follicle, determines the shape of the cortex, and the shape of the fiber is related to how straight or curly the hair is. Often, people who have straight hair own round hair fibers. In other contexts, oval and different shaped fibers are generally more wavy or curly. The diameter of human hair varies from 0.017 to 0.18 millimeters.

What is the lifespan of a strand of hair?

It is said that up to 150,000 sprouts from each human head. Each strand of hair grows at roughly one centimeter a month, creating the gross product per head about 10 miles of hair every year. Researchers have shown that a strand of hair reaches the end of its life and is shed after four years or so. Each of us loses around 50 strands of hair a day. And if we don’t have our hair cut in a long period of time, it can reach huge lengths. The world record is held by a Hindu holy man in the late 1940s. In his record, the man makes everyone surprised with his amazing tresses which were estimated at seven to eight meters.

How strong is a strand of hair?

You may think that a strand of your natural hair is weak. However, this is absolutely false. The fact is that hair is strong. A single strand of hair could hold about 100g in weight. The combined hair of a whole head could support 12 tons or the weight of two elephants. So amazing, right? Weight for weight, it is not as strong as steel: more like aluminum, or reinforced glass fibers or Kevlar, which is often used to make bulletproof vests.

Why do I have one strand of hair that is extremely long?

It seems quite strange but this is an ordinary question of many people. A person shares that “I suddenly found a strand of hair that was about 2 inches longer than the rest of my hair and I just cannot understand why it was so long”. At that time, the person got frustrated and pulled it out. Not a long time later, she met another similar situation with another strand of hair. This makes her so confused.
