How Many Hairs Are on the Human Head-Exploring Hair Density

What do you think, how many hairs are on your head? Most people indeed have around eighty thousand to one hundred fifty thousand (80,000-150,000) hair follicles on the head. Still, the number may vary according to hair color, density, and individual genetics. In this blog post, we will take a look at what determines the number of hairs on a person’s head, the hair density of diversity in hair color, and the degree and types of interesting facts concerning hair growth. 

The average human head

The number of hair follicles on the average human head is around 100,000. However, this number can be less or more accurate but can still depend on other factors such as hair color, age, and genetics. The particular hair color average hair count can be given as follows: Certain hair colors were found to produce an average: blonde hair: 120,000–150,000 hairs, brown hair: 100,000–120,000 hairs, black hair: 100,000–110,000 hairs, red hair: 80,000–90,000 hairs. 

Such variations are primarily due to the thickness of hair affecting its density, i.e. people with fine hair tend to have more strands while those with stiffer hair tend to have fewer strands since one follicle takes a lot of space per scalp area.

Factors That Affect Hair Count and Density 

The person may have a different number of hairs on his head, as well as different hair growth rates, hair density, and size. The key factors are: 

Hair Types 

In considering hair type, the number of hairs is evident. Blonde hairs tend to be the most concentrated with strands, followed closely by dark hairs and the least red hairs. Redheads usually will have a much heavier definition of the hair shafts.  

Genetics 

Genetic factors are also the critical ones in both hair counts, hair density, hair texture as well as other genetic traits possessed by the individual. If the individuals’ parents have a thick head of hair, chances are, they will also possess very thick hair density. 

Age 

When a person becomes older, the number of active hair follicles may shrink and therefore become the cause for the thinner hairs. Early adults have the broadest hair distribution than aged people. 

Hormones 

The above condition may also be seen in many cases during which the androgen hormones are present within the body structure as they affect the hair size, growth rate, and density of hair follicles. In girls, menopause or massive technique change, such circumstances may temporarily surge to hair count density, however, males have different patterned baldness and this decreases the hair counts.

Diet and Nutrition

In order to promote hair growth and thickness, it is important to follow a diet rich in vitamins and minerals like biotin, iron, and zinc. On the other hand, some deficiencies may also trigger hair loss or poor growth.

Hair Growth Cycle:

On the surface of the head, every follicle of the hair is subject to a cycle that involves growth, rest, and eventually, loss. This cycle includes three main phases:

Anagen (Growth Phase)

Anagen phase is also referred to as the active hair growth phase since hair cells divide for growth in this phase and it lasts between 2 and 6 years. At any given time, 85 to 90% of hair is in this phase of growth. 

Catagen (Transition Phase)

This phase lasts between two and three weeks and acts as a transition period. During this phase, hair is produced at a reduced rate and the follicle begins to contract. During the catagen phase, only 1% to 2% of hair is in this phase.

Telogen (Terminal of Growth Cycle)

The telogen phase is the last phase of the cycle and is also called the “resting phase” and it lasts for a period of about 3–4 months. Hairs do not grow during this phase. Rather those hairs remain attached to the follicle and will later shed out with a natural process to make space for new growth. There are about 10 and 15% of hairs in the telogen phase at any point in time for any individual.

It is generally accepted that most human beings lose a normal head of approximately 100 hairs per day as a result of natural loss. A reasonable amount of evidence indicates that this is indeed part of the growth cycle.

Some Interesting Facts About Hair On The Head of A Human Being

A hair growth rate

 researchers have concluded that the growth of hair takes an average of half an inch (1.25cm) in a month or six inches (15cm) in an entire year. 

Interhair area coverage

 a person with 100,000 hairs, the area which is covered with hair on the scalp for a fully grown and spread out hair all over the scalp is roughly 10 square feet

Individual hair continuity

 individual hair continuity can be estimated from the time frame between 2 and 7 years. Hair expects to grow any hair looking after genetic, individual health, and lifestyle factors have been taken into consideration as well.

Hair Strength

 Most hair experts agree that hair is one of the most durable materials. A single hair strand is capable of holding up to approximately 100 grams in weight. Hence, if we take into consideration the average number of hair strands a human has, it can be said that the head of hair can support the weight of 2 elephants.

Tricks for Hair Care

To protect the scalp and hair, as well as to guarantee the lifespan of the hair follicles, a person may do the following:

Balanced Diet

 Foods providing vitamin and mineral ingredients, especially iron and biotin as well as omega-3 fatty acids should be included in the diet as they are essential for healthy hair.

Over-Styling

 Overexposure to heat styling tools, chemicals, and tight hairstyles leads to the weakening and slicing of hair making it sparser.

Gentle Hair Care Products

 Most shampoos and conditioners contain sulfates which are harmful to the scalp so choose products with caring ingredients and no sulfates to avoid damaging the hair.

Scalp Massage

 Hair loss can be reduced by using scalp massage daily, as it encourages increased blood flow which enhances the delivery of nutrients to the follicles.

Decreased Stress Factors: Excessive stress can lead to loss of hair and interfere with the growth cycle, stress management techniques can help retain healthy hair.
