Hair Growth 101 – Fast Facts

Sharing is caring!


Hair is probably the most obvious thing you can see, but the human hair is far more complex than you would credit it for. Hair plays a big role in the way we look and has a direct impact on our confidence. Generally, in most cultures around the world, women tend to have longer hair than men.

There is nothing many men and women dread more than losing their hair and going bald; because baldness or loss of hair is a sign of aging and has a negative impact on our confidence. In this article, we discuss everything you need to know about hair growth.

Some of the terms related hair growth that you should know…

The human hair has two parts – the hair root which is just below the scalp and the hair shaft, which is the part of the hair that is visible to everyone and grows from the skin. Hair shaft has an outer layer called a cuticle, an inner layer known as medulla and a middle layer called cortex.

The hair follicle is a tube like structure which contains the hair root. The sebaceous gland is a gland of the skin which secretes sebum oil which provides lubrication to the hair, skin and the scalp.

How does the hair grow?

The first signs of hair are found in the developing fetus in week 22 when the hair follicles are formed. During this stage there are over 5 million hair follicles on the body, including one million on the head. There will be 100,000 hair follicles on the scalp. In fact, it is the human fetus that has the most number of hair follicles, much more so than a grown up man.  The density of the scalp hair reduces the older we get, and as we move from childhood to adult hood, and also because the scalp becomes bigger as we grow.

The Hair Growth Cycle

There are three phases in the hair growth cycle, and these phases repeat time and time again.

Anagen Phase– During this phase, the new hair grows. This phase usually lasts 3 to 5 years, but can be longer for some people. You may have seen men and women with a luxuriant growth of hair. It is possible that they have an especially long anagen phase. 90% of our hair is grown during this phase.

Catagen Phase– The catagen phase marks the end of the growth phase. It is when the hair growth transitions to the rest phase. Only 1% of the hair growth happens during this phase. It is a very short phase and a lasts just 14 days or so.

Telogen Phase– This is the phase during which the hair is no longer growing and actually starts shedding. Around 10 percent of human hair belongs to this phase and it lasts 3 to 6 months.

The different phases come together once the telogen phase ends, following which the anagen phase begins and the hair growth cycle starts all over again. This is one full hair growth cycle.

An average person grows about half-an-inch of hair every month.

Shedding hair

On a daily basis, an average person sheds between 100 to 150 pieces of hair. This is a natural process and is a part of the hair growth cycle. When pieces of hair are shed, it only means that new hair will grow in their place and it is nothing to be scared about. People shed and grow hair almost every day.

When should you start worrying about hair loss?

Shedding hair is a sign of a healthy scalp. However, when you start experiencing excessive hair loss, then you should be worried. It is suggested that those who are losing more hair than normal should visit a doctor immediately, as hair loss can be a symptom of a disease, or a side effect of a medication.

It could also mean that you are unable to deal with stress, either at the workplace or in a relationship. Hair loss can also be because of hereditary reasons. In fact, Male Pattern Baldness is generally caused by genetic factors.

How to prevent hair loss?

Any improvement in the nutrition and dietary habits, avoiding junk food or anything that contains too much sugar, salt and sodium; and increasing your intake of fruits and vegetables does help arrest hair loss to an extent. There are also several natural treatments for hair loss that you should try.  Finally, have plenty of water, as much as possible. Water gets rid of the toxins in the body that impede the growth of hair.
