The Composition of Hair
Before we dive into the numbers, let’s first understand what hair is made of and where it comes from. While we will focus on the hair on your head, it’s worth noting that all the hair on our bodies functions in the same way.
On your scalp, hair begins to form at the root, which is located inside a follicle, a tube-like structure in the outermost layer of the skin called the epidermis. Underneath the roots, your hair is composed of cells bonded together to form a protein called keratin. As your hair grows, shafts of hair emerge from the dividing cells of the hair matrix, which shares the foundation of the follicle with dermal papilla cells inside the hair bulb.
Let’s break down these parts one by one:
Dermal papilla cells are the core component of every hair follicle. They’re surrounded by blood vessels called capillaries and play a crucial role in determining the speed of hair growth and the life stage of the follicle.
The germinal matrix sits above the dermal papilla and is responsible for new hair growth. It transfers color to the hair through the transfer of melanin, the same compound that gives our skin a tan or makes a mole appear darker.
The hair bulb is a larger, round-shaped structure that includes the dermal papilla, germinal matrix, and the base of the growing hair shaft. It protects its contents and sits below the surface of the skin.
The sheath covers the outside of the growing hair shaft, giving it shape and structure. It’s like a holster for the hair shaft, similar to those worn by knights in fantasy movies.
The sebaceous gland, located closer to the skin’s surface, produces oil that lubricates our hair as it grows. We’re all familiar with clogged sebaceous glands that lead to unwanted pimples and acne.
The arrector pili is a tiny muscle that contracts to make our hair stand up, causing what we commonly know as goosebumps.
Why Do We Need Hair on Our Heads?
Hair is not just for show – it serves several purposes. Different types of hair on our bodies have different roles:
Body hair helps regulate our core temperature. It keeps us warm when we’re cold and acts as a motion sensor that detects bugs and other creatures on our skin.
Nasal hair acts as an air filter, preventing germs from entering our bodies when we breathe.
Eyelashes and eyebrows function as filters, catching dirt and dust to prevent them from getting into our eyes and causing irritation or infection.
The hair on our heads keeps us warm, and when well-maintained, it adds style and attractiveness to our appearance.
So, How Many Hairs Are on a Human Head?
While we have nearly five million hair follicles throughout our skin, the average person has approximately 100,000 hairs on their scalp. It’s important to note that we naturally lose about 50-100 hairs every day, which is completely normal. So don’t worry if you notice some hair falling out during brushing, washing, or even just sitting still. New hairs are constantly replacing the ones that have fallen out. Each hair on your head grows for about 2-6 years before entering a rest phase for a few months and finally falling out. The hair growth cycle then repeats, with a new hair growing from the same hair follicle.
Taking Care of Your Hair
While hair knows how to grow on its own, you can create an optimal environment to support hair growth. Here are some tips:
Consider using a natural shampoo free from harsh ingredients like sulfates or parabens to keep your scalp healthy and prevent the overgrowth of bacteria.
Use a scalp massager to encourage blood flow to your roots and stimulate the scalp, promoting health and restoration deep in the hair follicles.
Pay attention to your diet, as nutritional deficiencies can contribute to hair loss. Incorporate foods rich in iron, zinc, fatty acids, and vitamin D, which are beneficial for hair health.
