4 Hair Growth Cycle: Ultimate Life Span Of Hair

The Roots of Hair

The hair growth cycle begins like the development of an infant. A baby has the entirety of its hair follicles shaped. At this phase of your hair and life, there are around 5 million hair follicles on the body. There is a sum of 1,000,000 on the head, with 100,000 of those follicles dwelling on the scalp. This is the biggest number of hair follicles a human will have since we don’t create new hair follicles whenever throughout our lives.

Many people will see that scalp hair thickness is diminished as they develop from adolescence to adulthood.

The longevity of hair comprises four stages Anagen Catagen Telogen and Exogen. 

The Complete Life Span of Your Hair

Our hair is made up of two diverse parts- The follicles and the hair shafts. Let’s have a piece of the depth of knowledge.

The Follicles

The hair follicles are subdivided into four major parts: hair bulb, dermal papilla, arrector pili muscle, and sebaceous glands.

The hair follicle is a passage like a portion of the epidermis that stretches down into the dermis. The structure contains a few layers that all have separate capacities. At the base of the follicle is the papilla, which contains vessels, or little veins that support the cells. The living piece of the hair is the extremely base part encompassing the papilla, called the bulb. The cells of the bulb partition each 23 to 72 hours, surprisingly quicker than some other cell in the body.

  • Hair Bulb- It has a semi-curved shape which is located beneath the scalp. The round structure helps it to get locked by the Dermal Papilla.
  • Dermal Papilla- Precisely, Dermal Papilla is also found beneath the scalp. It is the cone-molded acme which is available at the base of your hair follicle. It finds a way into the hair bulb and holds it. The dermal papilla is associated with the blood vessels.
  • Arrector Pili Muscle- This muscle causes goosebumps when it contracts. It can be found at the base of the hair follicle.
  • Sebaceous Glands- These glands are responsible for secreting sebum from your hair as it has oil glands directly connected to the follicles.

The Hair Shafts

This is the visible part of the hair that grows outside the scalp. They are made up of Keratin and protected by a layer called ‘cuticle.’

In the hair growth cycle, this protein is, in reality, dead, so the hair that you see is certainly not a living structure. The internal layer is the medulla. The subsequent layer is the cortex, and the external layer is the fingernail skin. The fingernail skin is a firmly shaped structure made of shingle-like covering scales. The cortex and the medulla hold the hair’s shade, giving it its tone. Following are some parts of the hair shafts.

  • Cuticle- Beginning from the outermost layer, the cuticle is the hair’s protective layer, as we read. A strong and unified layer leads to shine and smoothness to your hair.
  • Cortex- Now comes the middle layer. The protein present in the cortex is liable for the flexibility and shade of your hair.
  • Medulla- The innermost layer of your hair is present only in the thick hairs.

Moving on,

Now comes the major section of the guide.

Hair Growth Cycle Explained

The Life Span of the Hair, which means hair growth stages, is divided into Four essential sections- Anagen Phase, Catagen Phase, Telogen Phase & Exogen Phase. The hair on the scalp develops around 0.3 to 0.4 mm/day or around 6 inches each year. In contrast to different vertebrates, human hair development and shedding are irregular and not occasional or repetitive.

1.Anagen Phase- The Growing Stage

Why is it a growing period? The Anagen Phase is the beginning of the cycle (The first stage of the Hair Growth Cycle), as this is the phase when your hairs start growing from the follicle root. Generally, this phase is the longest phase of the four. It takes about three to five years to grow hair. During this stage, the hair develops around 1 cm at regular intervals. Scalp hair remains in this dynamic period of development for two to six years.

However, the time varies from person to person. For some people, it takes seven or more than seven years. Like eyebrows and pubic areas, some parts of the body go through a short period of the Anagen Phase. In this stage, the hair grows up to 18 to 30 inches long.

2.Catagen Phase- The Modulation Phase

With the termination of the Anagen Phase starts the Catagen phase. As per the heading, this is a transitional phase that ends up in two to three weeks. In this temporary stage, hair quits developing and withdraws itself from the blood gracefully and is then named a club hair. During the catagen stage, the hair follicle reestablishes itself by contracting to 1/6 of its length, and the papilla rests. The catagen stage is momentary, and about 3% of all hairs are in this stage.

3. Telogen Phase- The Dormant Period

After comes the Telogen Resting Phase, which means the third stage of the hair growth cycle.

The telogen stage ordinarily keeps going around 3 months. An expected 10 to 15 percent of your scalp hairs are in this stage. Hairs don’t develop during the telogen stage; however, they don’t, as a rule, drop out by the same token. Likewise, the telogen stage is when new hair begins to grow in follicles that have recently delivered hairs during the catagen stage.

4. Exogen Phase- The Sloughing Era

Finally, the hair reached the last stage of the hair growth cycle, which instantly sheds hair while brushing or washing. This phase lasts for 3 to 5 months and leads to 50-100 hair falls per day.

Why the hairs shed?

During this phase, the old hair is lost, and new hair grows.

What Causes Split Ends?

Split Ends hairs- Barriers of a hair growth cycle. However, it gives a worse look to the hairs. The reason behind this is many. All hair types have to suffer from split ends, whether due to genes or other ethnic reasons. It can be caused due to the weather, water quality, or product you are using for your hairs. Well, actual speaking, it results in damage to two hair.

Alopecia is a bald sickness that can happen in anybody at any phase of life. Explicitly Alopecia areata is an immune system infection that makes hair suddenly drop out. It is chiefly described by uncovered patches on the scalp or different body pieces and can eventually cause hair sparseness over the whole body. This sickness meddles with the hair development cycle by making a follicle rashly leave the anagen, or dynamic development, stage and enter the resting, or telogen, stage. The hair development in the influenced follicles is diminished or halted totally.

Wondering how to get rid of damage? Here is something advantageous for you…

Prevention From Split Ends

Having weak hair shafts results in split ends and splits the hair-like fibers. This is a con for the hair growth cycle. Regular oiling can help your hair to get proper nourishment and smoothness.

Heating for long is also a culprit for having split ends. So, find out other natural methods despite heating. Other methods include using Flexi rods for curling and low flame dryers in place of straightening machines.
