The average human scalp is 120 square inches (774 square centimeters) in size. According to the Harvard Biological Numbers database, your hair’s color affects how many strands are on your head:

How Many Hairs On A Human Head Per Square Inch?
How many hairs are there on your head per square inch now that we know how many there are? This is referred to as hair density.
One older studyTrusted Source calculated hair density in 50 participants. They discovered that there were typically 124 to 200 hairs per square centimeter, or 800 to 1,290 hairs per square inch.
Hair Follicles Of Hairs On The Human Head
A hair follicle is a tiny pouch in your skin from which your hairs emerge. On your head, there are roughly 100,000 hair follicles. This closely matches the average number of hairs on your head, as you can see.
The stages that hair follicles cycle through include:
- Growth. The hair follicle is where hair growth happens. Between 85 to 90 percentTrusted Source of hairs are in the growth stage during a given period.
- Transition. Even though the hair is not growing at this stage, it is still inside the hair follicle.
- Resting. Hairs fall out of the follicle during this period.
This cycle can be broken occasionally. For instance, there might be a difference between the amount of hair that grows and the amount that sheds. This may result in hair loss or thinning of the hair.
What Is Hair Made Of?
The first thing you need to comprehend is the exact composition of hair and its origin. While the focus of this blog is on the hair on your head, it is important to remember that all of the hair on your body, whether it be on your legs, arms, or anywhere else, is created and functions in the same way.
The roots of the hair start to form on your scalp. The root is housed in a follicle, which is a tube-like structure in the epidermis, the top layer of the skin. Your hair is made of cells that are bound together to form a protein known as keratin underneath the roots. As your hair starts to grow from there, hair shafts will start to emerge upward from the dividing cells of the hair matrix, which shares the follicle’s core with dermal papilla cells found inside the hair bulb.
Let’s examine each of those components separately now:
- Dermal papilla cells are the core component of every hair follicle. They’re surrounded by blood vessels called capillaries, and the division of dermal papilla cells plays a part in how fast your hair grows, what stage of life your hair follicle is in, and more.
- The germinal matrix sits above the dermal papilla, and new hair growth comes from germinal matrix cells as they divide and push upward through the skin. They also transfer color to the hair, known as pigmentation, by transferring melanin, the same compound that makes a mole on our skin look darker or gives us a tan when we’re out in the sun.
- The hair bulb is the larger, round-shaped structure that includes the dermal papilla, germinal matrix, and the base of the growing hair shaft. It is embedded beneath the skin’s surface and shields its contents.
- The sheath covers the outside of the growing hair shaft, giving it shape and structure. Imagine the hair sheath as the holster for the sword that knights in those fantasy films wear around their waists if the hair shaft is like a sword.
- The sebaceous gland, closer to the skin’s surface, produces oil that lubricates our hair as it grows out. There are sebaceous glands everywhere, and we’re all familiar with how clogged sebaceous glands can result in unsightly pimples and acne.
- The arrector pili is a tiny muscle that contracts, or tightens, to make our hair stand up. Think goosebumps!
What Is Hair Growth Cycle?
- Anagen. The hair is actively growing during the anagen phase, which is a growth phase. This phase lasts for about three years.
- Catagen. The transitional phase is known as catagen. The rate of hair growth slows down a little during this phase, and the hair begins to separate from the follicle. This stage lasts for about two weeks.
- Telogen. The resting phase is called the telogen phase. This is when the hair stops growing but has not yet started to fall out. This stage of the hair cycle could last for three months.
- Exogen. In the shedding phase, also known as the exogen phase, hair falls out. New hair is also starting to grow within your follicles at this time.
Any of the aforementioned stages could be present in any one of your hairs at any given time. But occasionally this cycle is changed.
People going through hormonal changes like pregnancy, childbirth, or menopause may notice that their hair is either falling out much more quickly than usual or staying put.
Many people find post-partum hair loss alarming because it frequently happens suddenly; fortunately, this issue resolves itself on its own.
Additionally, until a condition is under control, certain medical conditions or treatments can alter your hair’s normal shedding. Even stress and poor nutrition can interfere with the natural growth cycle of your hair.
Maintaining good physical and mental health can prevent hair loss from exceeding the normal rate.
Why Do We Need Hair On Our Heads?
Hair keeps us looking good, but it also has practical uses. Depending on where it is on our bodies, our hair plays a variety of roles.
- The temperature of our bodies is regulated by body hair. Consider goosebumps as your hair’s way of casting a wider net to trap more heat. It not only helps us warm up when we’re cold!—but it also helps our bodies to notice things touching it. Consider every hair as a motion sensor that searches our skin for bugs, parasites, and other creepy crawlies that we might not otherwise notice!
- When we breathe, our nasal hair functions as an air filter to help prevent the entry of germs into our noses.
- Eyebrows and eyelashes serve as another kind of filter, removing dirt and dust that might otherwise enter the eye and irritate or infect it.
- The hair on our heads keeps us warm, but when it’s taken care of, it also looks fashionable and appealing.
Hair Density: Does Gender Matter?
Some people might think that gender influences hair density. However, it doesn’t appear that our head hair count is influenced by our gender. However, it does change the direction of hair growth.
In general, men’s hair tends to grow more quickly than women’s hair. Men who want to keep their hair a certain length must get it cut more frequently for this reason.
Can You Increase The Density Of Your Hair?
We assume that by this point you have a pretty good idea of how many hairs are on a human head. Your next concern might be whether you can make your hair more dense.
There is no way to increase our hair density because there are only a limited number of scalp hair follicles that can produce hair. After all, there is nothing we can do to produce more hair follicles.
But what we can do is make sure that we’re eating a healthy diet, which will guarantee that each hair follicle is supplied with the nutrients we need for normal hair growth.
There is no other way to increase the number of hair follicles on your head, but hair transplant surgery can help to increase hair density if you are experiencing severe hair loss.
We advise consulting a medical expert to go over your options if you’re experiencing hair loss or shedding. We’ll talk about how to deal with shedding and hair loss in the following section.
How Much Hair Loss Is Normal?
There are always stray hairs in the shower drain, between our fingers, or in the bristles of our favorite brush or comb when we shower or brush our hair.
Even on a regular basis, we might notice stray hairs on our clothes or bedding. Given that the average person loses between 50 and 100 hair strands per day, this is completely normal.
There’s no need to be concerned about this hair loss. Like the rest of our bodies, our hair experiences regular growth cycles.
