Telogen Effluvium:

Understanding the Causes, Symptoms, and Treatment

Hair loss can be a distressing experience for both men and women. There are various types of hair loss conditions, each with its own set of causes and treatment methods. One such condition is telogen effluvium, which is characterized a significant shedding of hair. In this comprehensive guide, we will delve into the details of telogen effluvium, including its causes, symptoms, and available treatments.

What is Telogen Effluvium?

Telogen effluvium (TE) is a type of hair loss condition that occurs when there is a disruption in the hair growth cycle. Typically, hair grows in a cyclic process, consisting of three phases:

anagen (growth phase), catagen (transition phase), and telogen (resting phase). During the telogen phase, hair strands are shed to make way for new hair growth.

In individuals with telogen effluvium, a significant number of hair follicles prematurely enter the telogen phase, leading to excessive hair shedding. Unlike other types of hair loss conditions, telogen effluvium is usually temporary and the hair follicles can recover and resume their normal growth cycle.

Causes of Telogen Effluvium:

There are various factors that can trigger telogen effluvium, disrupting the hair growth cycle. These causes can be categorized into three main types:

1. Physiological Causes:
– Hormonal fluctuations:

Significant hormonal changes, such as those experienced during pregnancy, childbirth, or menopause, can cause telogen effluvium. Additionally, thyroid imbalances, particularly hypothyroidism or hyperthyroidism, may also contribute to hair shedding.
– Nutritional deficiencies:

Inadequate intake of essential nutrients, such as iron, protein, vitamins, or minerals, can disrupt the hair growth cycle and lead to telogen effluvium. Common nutrient deficiencies associated with hair loss include iron deficiency anemia, vitamin D deficiency, and vitamin B12 deficiency.
– Rapid weight loss:

Sudden and extreme weight loss can also trigger telogen effluvium. Crash diets or eating disorders that severely limit calorie intake deprive the body of essential nutrients, causing hair follicles to enter the resting phase.

2. Psychological Causes:
– Emotional stress:

High levels of emotional or psychological stress, such as the loss of a loved one, divorce, financial difficulties, or work-related stress, can impact the normal hair growth cycle. Stress can disrupt the balance of hormones in the body, leading to hair loss.
– Chronic illness:

Serious illnesses or surgeries can cause telogen effluvium. The body diverts its resources towards healing, neglecting hair growth. Conditions such as liver disease, kidney disease, autoimmune disorders, or cancer can contribute to hair loss.

3. Environmental Causes:
– Medications:

Certain medications and treatments, such as chemotherapy drugs, anticoagulants, antidepressants, and retinoids, can trigger telogen effluvium as a side effect.
– Physical trauma:

Any significant physical trauma or surgery can shock the body, leading to hair loss. This trauma could include a car accident, major injury, or a surgical procedure.
– Environmental factors:

Exposure to environmental toxins, such as heavy metals, can disrupt the normal functioning of hair follicles, causing excessive shedding.

Symptoms of Telogen Effluvium:

The primary symptom of telogen effluvium is excessive shedding of hair. Unlike other forms of hair loss, telogen effluvium often presents as diffuse hair thinning rather than noticeable bald patches. This means that the shedding occurs evenly across the scalp, resulting in a decrease in hair density.

Other potential symptoms of telogen effluvium include:
1. Increased hair shedding during routine activities such as washing or brushing.
2. Worsening of hair loss when hair is subjected to tension, such as tying it back tightly or wearing hats.
3. An increased number of hairs on the pillow upon waking up in the morning.
4. A widening part line or visible scalp through the hair.

Diagnosis of Telogen Effluvium:

If you suspect you are experiencing telogen effluvium, it is recommended to consult a healthcare professional, preferably a dermatologist, who specializes in hair disorders. The diagnosis of telogen effluvium involves a thorough medical history review, physical examination, and possibly some additional tests to rule out underlying causes.

During the examination, the dermatologist will inspect the scalp and hair follicles for signs of inflammation or miniaturization. Blood tests may be conducted to identify any nutritional deficiencies or hormonal imbalances that may be contributing to the hair loss.

Treatment Options for Telogen Effluvium:

The good news is that telogen effluvium is often self-correcting, with most individuals experiencing regrowth of hair within a few months. However, there are certain steps you can take to promote hair regrowth and minimize further hair loss:

1. Identifying and managing underlying causes:

If telogen effluvium is triggered an identifiable cause, such as nutritional deficiencies or hormonal imbalances, addressing the root cause is crucial for recovery. This may involve adjusting your diet, incorporating supplements, or seeking appropriate medical treatment.

2. Nutritional changes:

Ensure you are consuming a well-balanced diet that includes an adequate intake of protein, iron, and vitamins essential for hair growth. Including foods such as lean meats, fish, fruits, vegetables, nuts, and whole grains can provide the necessary nutrients for hair follicle health.

3. Stress management:

Since psychological stress is a common trigger for telogen effluvium, it is important to adopt stress management techniques. These may include regular exercise, meditation, deep breathing exercises, or seeking therapy or counseling to handle emotional stress.

4. Gentle hair care practices:

Avoid subjecting your hair to excessive tension, heat, or chemical treatments that can further damage fragile hair follicles. Opt for gentle hair care routines, using mild shampoos and conditioners, and avoiding tight hairstyles that pull on the hair.

5. Topical treatments:

Depending on the severity of telogen effluvium, a dermatologist may recommend topical treatments to promote hair regrowth. These may include minoxidil, a topical solution applied to the scalp, or corticosteroid injections to stimulate hair growth.


Telogen effluvium, characterized the excessive shedding of hair due to disruption in the hair growth cycle, can be a distressing experience. Understanding the causes, symptoms, and available treatment options can help individuals navigate through this condition with confidence. Remember that telogen effluvium is often temporary, and with proper management of underlying causes, healthy hair regrowth can be achieved. If you suspect you have telogen effluvium, it is always recommended to consult with a healthcare professional for an accurate diagnosis and personalized treatment plan.
