PARTS OF HAIR | THE SCIENCE OF HAIR

Before you going to know about the hair growth cycle firstly you need to about hair parts. There are three parts of your Hair The hair shaft, The hair root, The hair follicle.

                                                   What is the structure and function of the hair follicles?

The Hair Root- The root of the hair ends in an enlargement, the hair bulb, which is whiter in color and softer in texture than the shaft, and is lodged in a follicular involution of the epidermis called the hair follicle. 

The bulb of hair consists of fibrous connective tissue, glassy membrane, external root sheath, internal root sheath composed of epithelium stratum (Henle's layer), and granular stratum (Huxley's layer), cuticle, cortex, and medulla.


The hair follicle- The hair follicle is an organ found in mammalian skin. It resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions. 

The hair follicle regulates hair growth via a complex interaction between hormones, neuropeptides, and immune cells.


The hair shaft-Your hair shaft is that the part of your hair will be seen above your scalp. It is made from a protein called keratin, compacted, and fused together.

Keratin is that the same material that nails, hoofs, feathers, and claws are composed of Keratin may be a remarkably strong protein, very immune to wear and tear. 

It is held together by two kinds of bonds: disulfide bonds and hydrogen bonds.

disulphide bonds are extremely durable. In fact, they are one of the strongest naturally occurring bonds in the world. 

When you permit or relax your hair, these disulphide bonds are broken and reset into a different configuration. This is what allows you to permanently change the form of your hair.

Hydrogen bonds are weaker and more numerous than disulfide bonds. They help give your hair its flexibility. 

When you wet your hair, they're easily broken and maybe temporarily reset with heat until they become wet again (either from water or humidity). 

This is what allows you to style your hair with hairdryers and tongs after washing.

HOW DOES THE HAIR GROWTH CYCLE WORK? | Hair Growth Cycle - The 4 Stages Explained

There are 4 stages of the hair growth cycle, from starting growing of hair from the root to hair shedding. 

These are known as the Anagen phase, the Catagen phase, the Telogen phase, and Exogen (Hair Shedding) Phase.

 THE ANAGEN PHASE

This is the first stage of the hair growth cycle and is also called the growth period or the Anagen Phase. 

In this phase, the cells in the hair bulb divide themselves rapidly creating the growth of new hair. 

The hair follicles become inactive after 2 to 7 years. Before this, the hair remains in the anagen phase for 2 to 7 years and grows rapidly, And during this 2 to 7 years your hair grows to a minimum of 18 to 30 inches. 

The length of this phase depends on healthy hair. If your hair is healthy then increases to the maximum length, And many other reasons also depend like genetic, age, health. 

THE CATAGEN PHASE

The second phase of your hair that comes after the anagen phase is called the catagen phase.

 The second phase of your hair, ie, the catagen phase lasts for a very short time, that is, it lasts for 2 to 3 weeks.

 In this phase, your hair stops growing and detaches itself from the blood supply. This hair is called club hair.

THE TELOGEN PHASE

This is the third phase of hair that comes after the catagen phase which is also known as the telogen phase.

 In this phase, your hair stays in the resting phase, Where the club hair rest in the roots new hair starts growing from below. Your hair lasts about 3 to 6 months in this phase.

Exogen (Hair Shedding) Phase

This is the last phase of hair that comes after the Telogen phase which is also known as the Exogen (Hair Shedding) Phase. 

After 3 months your club hair falls out to allow new hair to come out through the follicles. There is nothing to worry about it. 

This is a natural process that should go completely unnoticed. Each one goes through a growth cycle at different times so that you do not lose your hair patch at once. 

You only lose 50 to 100 hairs every day. 80 to 90% of your hair remains in the anagen phase and these hairs growing rapidly and strong.

 After the exogen phase, the follicle then returns to the anagen phase, and the cycle repeats.

Your hair stays in the first phase of the hair growth cycle i.e 2 to 7 years in the anagen phase and during this time your hair keeps growing rapidly.

 Your hair needs adequate nutrients to grow properly and should be in the harmonic balance of your body. 

If you facing hair loss problem or hair thinning then its means hair growth may occur when your growth cycle is disrupted. 

This can be triggered by conditions such as metabolic imbalances, hormonal imbalance, illness, improper nutrition, stress or medication, surgery, pregnancy or menopause, etc.

For example, If you getting more stress or 6 weeks after restrictive dieting or a high fever or surgery or childbirth you may experience telogen effluvium (sudden diffuse hair fall).

 This happens when there is an obstruction in the growth cycle of the hair in your anagen phase due to some reason, for this reason, many hairs go into the telogen phase at the same time. 

If your hair growth cycle is getting interrupted repeatedly or your hair is not getting an adequate amount of nutrients then you may find that your hair will not grow as long as it used to. 

This happens because the hair of your anagen phase goes into the resting phase for some reason and your hair stops growing.



How does hair growth cycle related to your hair loss problems?

In any healthy person usually, the ratio of Anagen (Growing Phase) and Telogen (Resting Phase) is the same. 

About 90% live in our Anagen phase and 10% live in our Telogen phase. every day we have some hair fall and the same new hair comes back again and grows.

That is why there is a maintenance balance between hair fall and hair growth.

This daily shading is a normal phenomenon and normal hair growth is only one part of the cycle.

Who has thick hair on his head and any healthy person 100 to 150 hair fall is a simple thing.

During your bath you can see that your hair is falling or while doing kanji you can see that your hair is falling a little bit, then you do not need to panic. such a simple thing.

But the problem occurs when the ratio between anagen and telogen phase becomes suddenly changes. 

When the majority who anagen phase hair they prematurely go into the telogen phase.

They leave before completing their 6-year 8-year term this is the biggest problem. they go away before time and there is no more hair in the anagen phase. 

Moreover, the anagen phase suddenly starts getting smaller and it turns 8 months instead of 8 years.

That is why less hair grows in the anagen phase and more hair falls in the telogen phase. 

Due to this imbalance, we face the problem of hair fall. Nowadays more than two types of hair fall problems are found in everyone.

One of these two is named Androgenetic Alopecia, also known as pattern alopecia and the second named is Telogen Effluvium.

But what exactly is this androgenetic alopecia? and what happens in this telogen effluvium. 

Hair fall comes in androgenetic alopecia and also in telogen effluvium but what is the difference between them.

Let us understand these two carefully fast  Androgenetic Alopecia is what we call male or female pattern baldness. 

In this, your hair becomes eventually thin out and your anagen hair gets miniaturization and he goes into telogen phase before time.

Anagen hair is reduced and converted to the telogen phase, before the time it is not a sudden process, it is a slow process, it is a slowly occurring process that keeps happening slowly.

Anagen phase to telogen phase conversion process takes many years and many months to go. 

This process in baldness and pattern baldness hair fall, a process that runs slowly for many years.

InTelogen Effluvium, the anagen phase hair converts to the telogen phase on many days or many months in this situation your hair is converted suddenly or fastly.but during Androgenetic Alopecia, the hair starts becoming weak and hair follicles start miniaturization and baldness.

In this process, your hair is converted into many stages that are first thick hair than thin hair then go vellus hair then baby hair and then no hair gradually in this last stage your hair follicles die.

These prematurely become miniaturization this happens because of the effect of Dihydrotestosterone hormone and there are many reasons why this baldness is fast, it does not happen just because it is affected by the hormone and there are many reasons.

It is not just due to hormones and it is happening for many reasons. for this hair fall problem, due to which the hair of people falls at an early age.

But this is happening due to some of the reasons, which is that stress, the lake of exercise and lake of proper sleep and fate dieting those are thinks.


Due to these reasons, the effect of DHT(6) hormone starts appearing in your hair and your hair starts falling. and the reactions of this hormone can be easily seen in your weak hair.
