What Happens During The Telogen Phase Of The Hair Life Cycle?

During the hair growth cycle, the telogen phase is one of the main phases that hair follicles go through.

It is often referred to as the "resting" phase.

Here's what happens during the telogen phase:

Hair Follicle Rests

In the telogen phase, the hair follicle is not actively producing new hair.

Instead, it enters a resting state, which lasts for a certain period of time.

This period can vary from a few weeks to a few months, depending on factors such as genetics and overall health.

Old Hair is Shed

The old hair strand that was in the previous growth phase (anagen) remains anchored in the follicle, but it is no longer growing.

The hair shaft becomes detached from the hair bulb at the base of the follicle. However, this shedding process is not immediately noticeable, as only about 10-15% of scalp hairs are typically in the telogen phase at any given time.

New Hair Begins to Form

While the old hair is in the telogen phase, a new hair is starting to form beneath it in the hair follicle.

This new hair is in the anagen phase, which is the active growth phase.

Hair Cycle Continues

After the telogen phase is complete, the hair follicle re-enters the anagen phase, and the new hair strand begins to grow, pushing the old, resting hair out of the follicle.

This cycle of growth, rest, and shedding continues throughout a person's life.

How Long Is The Telogen Phase For Body Hair?

The duration of the telogen phase can vary depending on the area of the body.

For scalp hair, the telogen phase typically lasts around 2 to 4 months, while body hair may have a shorter telogen phase of about 1 to 2 months.

Keep in mind that these are approximate timeframes and can vary from person to person.

What Causes Hair To Enter The Telogen Phase?

Hair follicles can enter the telogen phase due to a variety of factors and triggers.

Here are some common causes that can lead to hair follicles transitioning into the telogen phase:

Natural Hair Cycle

Hair follicles naturally go through cycles of growth, rest, and shedding.

It's a normal part of the hair growth process for a certain percentage of hair follicles to be in the telogen phase at any given time.


Physical or emotional stress can disrupt the normal hair growth cycle and push more hair follicles into the telogen phase.

This type of hair shedding is often temporary and is known as "telogen effluvium."

Illness and Medical Conditions

Certain illnesses, infections, and medical conditions can trigger a shift of hair follicles into the telogen phase.

This can include fevers, surgeries, chronic illnesses, and hormonal imbalances.

Hormonal Changes

Hormonal fluctuations can affect the hair growth cycle.

For example, pregnancy and childbirth can cause shifts in hormone levels that lead to temporary hair shedding and the telogen phase.

Nutritional Deficiencies

Inadequate intake of essential nutrients, particularly protein, iron, and certain vitamins, can disrupt the normal hair growth cycle and contribute to hair entering the telogen phase.


Some medications, such as certain antidepressants, anticoagulants, and blood pressure medications, can cause hair follicles to enter the telogen phase as a side effect.

Sudden Weight Loss

Rapid and significant weight loss, often associated with crash diets or eating disorders, can lead to hair shedding and the telogen phase.

Physical Trauma

Any significant physical trauma to the body, such as surgery, injury, or severe illness, can prompt a larger number of hair follicles to enter the telogen phase.


As individuals age, the hair growth cycle can change, and more hair follicles might enter the telogen phase.

This can result in gradual thinning of the hair over time.

What Is The Telogen Phase Of Stress?

Stress can play a significant role in disrupting the hair growth cycle.

When the body undergoes stress, it can shift a larger number of hair follicles into the telogen phase.

This phenomenon is known as telogen effluvium.

It's a temporary condition that often leads to increased hair shedding but can be managed with proper care and stress reduction techniques.

What Is An Example Of A Telogen Phase?

An example of the telogen phase can be observed when you notice an increase in hair shedding after a stressful event, major surgery, or giving birth.

These life events can induce a higher number of hair follicles to enter the telogen phase simultaneously.

Remember, this is usually temporary and reversible.

What Is The Telogen Phase?

The telogen phase, often referred to as the "resting phase," is a natural stage in the hair growth cycle where hair follicles temporarily stop actively growing.

Instead, they enter a resting state, maintaining their position within the follicle until the cycle restarts.

This phase is a vital part of the hair growth process, contributing to the overall health and longevity of your hair.1

Why Is The Telogen Phase Important?

Understanding the importance of the telogen phase is crucial for anyone aiming to achieve and maintain healthy hair.

This phase allows hair follicles to reset and prepare for new growth, ensuring that your locks grow strong and vibrant.

Without this resting phase, hair growth could become erratic and compromised.

Here are the several key roles in maintaining healthy hair and the overall hair growth process:

Renewal and Regeneration

The telogen phase allows for the shedding of old, non-growing hairs.

This shedding is essential for making space for new hair growth.

As old hairs are shed and new hairs enter the anagen phase, the hair follicles undergo a continuous cycle of renewal and regeneration.

Preventing Overcrowding

Hair follicles cannot sustain indefinite hair growth without periods of rest.

If all hair follicles were in the anagen phase simultaneously, there would be overcrowding and competition for resources, potentially leading to weaker and thinner hair.

Hair Health

The telogen phase helps maintain the overall health of the hair follicles.

During this phase, the hair follicles can repair and rejuvenate themselves, preparing for the next growth phase.

Natural Shedding

Shedding old hairs during the telogen phase is a natural process that helps remove damaged or weakened hairs from the scalp.

This can lead to the growth of healthier, stronger hairs during the subsequent anagen phase.

Adapting to Environmental Changes

The hair growth cycle, including the telogen phase, can be influenced by changes in the environment, such as seasonal changes.

This adaptation allows the body to optimize hair growth according to external factors.

Indicator of Health

An imbalance or disruption in the hair growth cycle, including an increased number of hairs in the telogen phase, can sometimes be an indicator of underlying health issues or stress.

Monitoring changes in hair shedding and growth can help identify potential health concerns.

Cyclic Nature of Hair Growth

The hair growth cycle is a dynamic and cyclic process.

Without the telogen phase, the cycle would be incomplete, and the hair would not follow its natural pattern of growth, rest, and shedding.

How Does The Telogen Phase Work?

During the telogen phase, hair follicles undergo a transition where the hair strand disconnects from the follicle's blood supply.2

This is followed by a period of rest that lasts for a few months.

Once the rest period concludes, the follicle re-energizes, and a new hair strand begins to grow.

This cycle of rest and regrowth contributes to the continuous renewal of your hair.3

What Are The Benefits Of The Telogen Phase?

The telogen phase offers several benefits that contribute to the overall health and appearance of your hair:

Natural Renewal

The rest period allows hair follicles to rejuvenate, leading to stronger and healthier hair growth.

Even Growth

By having hair strands enter the growth phase at different times, the telogen phase contributes to more consistent and even hair growth.

Maintenance of Hair Structure

The pause in growth helps maintain the structural integrity of the hair shaft, preventing breakage and promoting shine.

Are There Any Downsides To The Telogen Phase?

While the telogen phase is a necessary part of the hair growth cycle, there are some considerations to keep in mind:

  • Temporary Shedding: As older hair strands prepare to shed during the telogen phase, you might experience increased hair shedding. This is usually temporary and makes way for the growth of new, healthy strands.

  • Transition to Growth: Some individuals might notice a brief lag between the end of the telogen phase and the start of new hair growth, which is a normal part of the process.

What Are The Alternatives To The Telogen Phase?

The telogen phase is an inherent part of the hair growth cycle and doesn't have direct alternatives.

However, various external factors can disrupt the cycle or lead to excessive hair shedding.

It's essential to focus on factors that can positively influence hair health:


A balanced diet rich in vitamins and minerals supports healthy hair growth.

Stress Management

Reducing stress levels can prevent excessive hair shedding due to stress-induced telogen effluvium.

Hair Care Routine

Using appropriate hair care products and avoiding harsh treatments can help maintain hair health during all phases of the cycle.

Frequently Asked Questions About Telogen Phase

Does the telogen phase affect all hair types equally?

Different hair types can have varying responses to the telogen phase.

However, the underlying process remains the same across all hair types.

Can hair care products influence the duration of the telogen phase?

Hair care products can impact the overall health of your hair, but they typically don't directly affect the duration of the telogen phase.

Is hair loss during the telogen phase permanent?

No, hair loss during the telogen phase is usually temporary.

Once the resting phase is over, new hair growth will commence.

Are there any remedies to promote hair growth during the telogen phase?

Maintaining a balanced diet, managing stress, and using hair care products formulated to support growth can all contribute to healthier hair during the telogen phase.

Should I consult a doctor if I experience excessive hair shedding?

If you notice sudden and severe hair shedding, consulting a healthcare professional or a dermatologist is advisable to rule out any underlying medical conditions.

What Triggers Excessive Hair Shedding during the Telogen Phase?

Excessive hair shedding during the telogen phase can be triggered by factors such as sudden weight loss, major surgeries, high fever, or hormonal changes.

These events can cause a larger number of hair follicles to enter the resting phase simultaneously.

Can Hair Care Products Prolong the Telogen Phase?

Hair care products play a significant role in maintaining hair health, but they typically don't prolong the telogen phase itself.

Instead, they contribute to overall hair strength, shine, and manageability during all stages of the hair growth cycle.

Is the Telogen Phase the Same for Everyone?

While the general pattern of the telogen phase is consistent, the duration and timing can vary from person to person.

Factors like genetics, age, and overall health can influence how long the resting phase lasts.

Can Stress Extend the Telogen Phase?

Stress can lead to a condition called telogen effluvium, where an increased number of hair follicles enter the telogen phase.

However, the phase itself is a natural part of the cycle, and reducing stress can help minimize its impact.

Can You Prevent Hair Loss During the Telogen Phase?

While you can't completely prevent hair loss during the telogen phase, you can take steps to minimize its effects.

Maintaining a healthy lifestyle, managing stress, and using hair care products formulated to support hair health can all contribute to better overall hair condition.
