how long does the telogen or resting stage of hair growth last?

Hair growth is a complex process with three main phases: Anagen (growth phase), Catagen (transition phase), and Telogen (resting phase). 

During the Telogen phase, the hair follicles are dormant, which means the hair does not actively grow during this time.

Instead, it remains firmly anchored in the scalp until the next cycle begins, in which the hair sheds. 

So, how long does the Telogen or resting stage of hair growth last? And what could cause it to influence its duration?

Keep reading to find out answers to these questions and learn tips to reduce hair fall that follows the Telogen stage.

The duration of the Telogen phase

On average, the Telogen lasts for about four months.

At any given time, 10% to 15% of the total amount of hair on the body is in the resting stage.

A change in this phase pushes the hair to the shedding phase, which can be seen as excessive hair fall.

However, individual variations are common, and some people may experience a shorter or longer Telogen period. 

The duration of this phase can be influenced by various internal and external factors, which we will discuss in the following section.

Fact:
When there is a sudden increase in the shedding of the hair due to premature entry of hair follicles into the Telogen phase, the condition is Telogen Effluvium.

Factors influencing duration of Telogen phase

The following factors might cause changes in the length of the Telogen phase:

Genetics

The duration of the Telogen phase is influenced by genetics, making it one of the most significant factors determining the length of an individual’s hair growth cycle. 

Each person inherits a unique genetic makeup that governs various aspects of their hair, including the time spent in the resting stage. 

Consequently, some individuals may naturally have shorter or longer Telogen phases compared to others. 

Age

The aging process affects the regenerative capabilities of hair follicles.

It causes gradual miniaturization of the follicles leading to a gradual reduction in hair density. 

While age-related changes are inevitable, adopting a holistic approach to hair care and overall health can mitigate the impact of aging on hair growth.

To begin, keep your scalp clean and well-nourished. 

Regular scalp massages can help stimulate blood flow to the hair follicles, promoting healthy hair growth.

In addition to this, refrain from tight hairstyles or using chemicals that can damage the hair shaft and weaken the follicles.

Stress and lifestyle

Stress (may affect hair growth)

High-stress levels and an unhealthy lifestyle can disrupt the hair growth cycle, leading to an increased amount of hair follicles entering the resting stage prematurely. 

As a result, there may be noticeable hair shedding and potential hair loss. 

Managing stress through relaxation techniques, engaging in regular exercise, and adopting a well-balanced lifestyle can contribute to a healthier hair growth cycle.

Warning:
Do not make any substantial changes in your diet without consulting your healthcare provider or nutritionist.

Nutrition and diet

Proper nutrition is fundamental for healthy hair growth, and deficiencies in certain vitamins and minerals can affect the hair growth cycle, including the Telogen phase. 

Nutrients such as biotin, vitamins A, C, D, E, Iron, Zinc, and Selenium are essential for supporting optimal hair health

Incorporating a balanced diet rich in these nutrients can promote a balanced hair growth cycle, potentially extending the duration of the anagen phase and reducing hair shedding.

Hormonal changes

Hormonal fluctuations play a pivotal role in influencing the duration of the Telogen phase. 

Events such as pregnancy, childbirth, menopause, or thyroid imbalances can lead to significant hormonal shifts, disrupting the hair growth cycle. 

During these periods, the Telogen phase may be affected, resulting in temporary hair shedding. 

While these changes are usually transient, seeking medical guidance and hormone management when necessary can aid in restoring a healthy hair growth cycle.

Medical conditions and treatments

Consult a healthcare professional

Certain medical conditions, such as Alopecia Areata or treatments like Chemotherapy, can have a huge impact on the normal hair growth cycle, including the Telogen phase. 

These conditions may lead to significant hair loss as they disrupt the hair follicles’ natural regenerative processes. 

However, if you experience sudden and excessive hair shedding or hair loss, it is essential to consult a healthcare professional or a dermatologist. 

They can assess your condition, identify any underlying issues, and recommend appropriate treatments.

Takeaway

The Telogen phase is a crucial part of the hair growth cycle, during which hair follicles rest and prepare for the next growth phase. 

While the average duration of this phase is about four months, individual variations exist due to genetic, lifestyle, and hormonal factors. 


Factors such as age, genes, and lifestyle play a huge role in determining the duration of this phase.

Additionally, hormonal changes and certain medical conditions could also contribute to a disrupted hair growth cycle. 

A gentle hair care routine, stress-reducing techniques, and a well-balanced diet can help reduce the hair loss caused by Telogen Effluvium.

In case of severe or sudden and excessive hair loss, consult a healthcare professional immediately.

Frequently Asked Questions

How long is hair in Telogen?

The Telogen phase, or the resting phase of hair growth, typically lasts around 2 to 4 months. During this stage, hair follicles are dormant, and hairs remain attached to the scalp until they are shed naturally.

How long does each stage of hair growth last?

The hair growth cycle consists of three stages: Anagen (active growth), Catagen (transition), and Telogen (resting). Anagen lasts for about 2 to 6 years, catagen for 2 to 3 weeks, and Telogen for 2 to 4 months.

Can hair still grow in the Telogen phase?

During the Telogen phase, hair remains attached to the follicle without active growth. Around 10-15% of hair is typically in this resting stage. Subsequently, the hair follicle reenters the Anagen phase, initiating the formation of new hair.
