Have you ever wondered how many hairs does an average person have on their head? It’s a common question, but there are many factors that affect this number.
One of these factors is hair density. This depends on several things including race and hair color.
Hair Density
Hair density is a measurement of the number of hairs in one square inch of your head. The average person has about 2,200 strands of hair within one square inch of their scalp, but this can vary.
Density can be determined in a few different ways. The most accurate is a strand test, where someone counts every strand in a 1-inch square patch of your scalp. This can be a tedious process, but it is the most accurate method available.
Another method involves a scalp density assessment done by a professional. This is a faster and more accurate way of determining your density.
Gender
The average person has around 100,000 hairs on their head, but it varies from person to person. Gender, age, and natural hair color all play a role in determining how many strands you have on your head.
The long and the short of it is that this number can vary a lot from one person to the next, depending on their height, diet, lifestyle, and general health.
The most impressive numbers belong to blondes, who get an estimated 150,000 hairs on their heads, followed closely by brown haired folks with 110,1000 follicles. Redheads are a bit behind the curve, with an average of 90,000 hair follicles per square inch.
Race
There are three main classifications of hair type based on race: Asian, Afro and Caucasian (or European). All three categories have unique hair properties such as shape, color and follicle size. But there’s no question that the most interesting strands of hair on a human head are the ones that have migrated from one ethnicity to the next over time.
Although the concept of comparing hairs from different ethnic groups is still considered taboo in many circles, a plethora of empirical data indicates that hairs are indeed forged from follicles of mixed ilk. The most important takeaway from this research is that hairs are a complex assemblage of molecules, and a variety of other factors can contribute to their uniqueness. The biggest challenge is determining which of these elements is the most crucial to achieving your desired hair type.
Hair Color
The average person has about 100,000 hairs on their head. But that number can vary depending on the individual and their hair color.
People with blonde hair typically have the most follicles in their scalp, averaging close to 150,000. They are followed by brunettes with about 110,000 follicles.
The color of a person’s hair is determined by eumelanin and pheomelanin, which are pigments in the strands of their hair. A higher percentage of eumelanin gives someone dark hair, while a lower percentage of pheomelanin results in lighter colors like blond and red.
Hair Loss
An average person loses 50 to 100 hairs a day. This usually isn’t noticeable because new hair is growing in at the same time.
Hair loss is caused by a number of different things, including extreme physical stress or shock to the body (e.g., surgery or severe illness), medication, hormonal changes during pregnancy and menopause, and thyroid problems.
Eating disorders like anorexia and bulimia may also cause hair loss. This happens because the body isn’t getting enough protein, vitamin and minerals it needs to support hair growth.
Medical conditions may also contribute to hair loss, including alopecia areata and lichen planopilaris, which causes patches of hair to fall out on the scalp. It’s also sometimes a side effect of certain medications, such as those used for cancer, depression, heart disease and gout.
