Understanding Telogen Effluvium: Causes, Symptoms, Treatments, and Prevention of Temporary Hair Loss
Telogen effluvium hair loss occurs when a large number of hair follicles prematurely enter the resting (telogen) phase of the hair growth cycle, leading to noticeable shedding and diffuse thinning across the scalp.
Unlike permanent hair loss, telogen effluvium typically resolves on its own once the underlying cause is addressed, with hair regrowth usually occurring within a few months. In this article, we will discuss telogen effluvium hair loss, its causes, symptoms and treatment options. So, read this until the end!

Introduction
Hair loss can be distressing, affecting not only physical appearance but also self-esteem and confidence. While various types of hair loss exist, one of the most common forms is telogen effluvium. This condition, often triggered by significant physical or emotional stress, results in temporary hair shedding that can be alarming for those experiencing it. Unlike genetic hair loss or permanent alopecia, telogen effluvium hair loss can be reversible if appropriately managed.
Let's delve into the causes, symptoms, treatment options, and preventive measures for telogen effluvium, offering insights for those looking to understand and address this type of hair loss.
What is Telogen Effluvium Hair Loss?
Telogen effluvium (TE) is a form of hair loss characterized by excessive shedding of hair in the telogen (or resting) phase of the hair growth cycle. Under normal conditions, approximately 85–90% of hair follicles are in the growth (anagen) phase, while only about 10–15% are in the resting (telogen) phase. However, when a person experiences telogen effluvium hair loss, a larger percentage of hair follicles prematurely shift to the resting phase, leading to noticeable shedding. This type of hair loss is typically temporary and can resolve on its own once the underlying cause is addressed.
Telogen effluvium differs from other forms of hair loss in that it does not result in complete baldness but rather diffuse thinning that can affect the entire scalp. This thinning can be particularly distressing as it often leads to a sudden increase in shedding, which many people notice during washing or brushing.
Causes of Telogen Effluvium
Telogen effluvium hair loss is usually triggered by factors that disrupt the normal hair growth cycle, leading to premature entry of hair follicles into the resting phase. Common triggers include:
- Physical Stressors: Significant physical stress such as surgery, illness, injury, or high fever can disrupt hair growth and push follicles into the resting phase. Events like COVID-19 infections, which cause systemic inflammation and fever, have led to increased reports of telogen effluvium.
- Emotional Stress: Major life events, including the death of a loved one, job loss, or other emotional trauma, can also lead to telogen effluvium. Psychological stress is known to impact the immune system and hormonal balance, which can affect hair growth cycles.
- Hormonal Changes: Hormonal fluctuations, especially in women, are a common cause of telogen effluvium. Pregnancy, childbirth, menopause, and discontinuation of birth control pills can all trigger hormonal shifts that affect hair growth.
- Nutritional Deficiencies: Diets lacking essential nutrients, particularly iron, zinc, and biotin, can weaken hair follicles and disrupt the growth cycle. Rapid weight loss, anorexia, or other eating disorders can lead to deficiencies that promote telogen effluvium.
- Medications: Certain medications, including antidepressants, anticoagulants, and beta-blockers, can induce telogen effluvium as a side effect. Chemotherapy, in particular, is known for causing significant hair loss.
- Chronic Illnesses: Conditions such as thyroid disorders, lupus, or severe infections can influence hair growth patterns, leading to telogen effluvium. Thyroid imbalances, whether hyperthyroidism or hypothyroidism, are especially common contributors.
- Environmental and Lifestyle Factors: Extreme weather, pollution, and exposure to chemicals can weaken hair over time, making it more susceptible to stress-induced shedding.
Symptoms of Telogen Effluvium
Recognizing telogen effluvium hair loss is essential for managing it effectively. The symptoms typically include:
- Diffuse Thinning: Unlike other types of hair loss that target specific areas, telogen effluvium results in general thinning across the scalp. This thinning is often most noticeable at the crown.
- Increased Shedding: Hair shedding often becomes more noticeable during shampooing, brushing, or even touching the hair. This can lead to an alarming amount of hair fall on pillows, in drains, or on clothes.
- Hair Texture Changes: Some individuals notice that new hair growth may feel finer or thinner than before. This is typically temporary, and the hair can return to its original texture with time.
- Shorter Hair Lengths: Since telogen effluvium affects hair growth cycles, you may notice an increase in shorter hairs as they regrow after shedding. These new hairs often stand out from the rest, particularly around the hairline.
- Delayed Onset of Symptoms: Unlike immediate hair loss caused by physical damage or alopecia areata, telogen effluvium symptoms often appear 2–3 months after the triggering event. This delayed onset can make identifying the cause more challenging.
Diagnosis of Telogen Effluvium
Diagnosing telogen effluvium hair loss involves a comprehensive approach, as the symptoms can resemble other types of hair loss. The following methods are commonly used:
- Medical History Review: Doctors typically review a patient’s medical history, lifestyle changes, recent physical or emotional stressors, medications, and diet. This helps identify any potential triggers for telogen effluvium.
- Scalp Examination: A visual examination of the scalp can reveal patterns of hair thinning. In telogen effluvium, diffuse thinning across the scalp is typical, with no localized bald patches.
- Pull Test: In this test, a doctor gently pulls on small sections of hair to determine the extent of hair shedding. If more than 10% of the pulled hair comes out, it may indicate telogen effluvium.
- Trichogram or Trichoscopy: These diagnostic tools involve examining hair follicles under a microscope to determine the percentage of hair in each growth phase, helping to confirm the presence of telogen effluvium.
- Blood Tests: Blood tests can identify nutritional deficiencies, hormonal imbalances, or underlying health conditions that may contribute to telogen effluvium. Thyroid function tests, iron levels, and vitamin D levels are commonly checked.
Treatment Options for Telogen Effluvium Hair Loss
Telogen effluvium is often self-resolving, meaning that once the triggering factor is addressed, hair growth gradually returns to normal. However, several treatment options can support recovery and help reduce hair loss.
1. Addressing Underlying Causes
The first step in treating telogen effluvium hair loss is to address the root cause, whether it’s dietary, hormonal, or stress-related.
- Nutritional Support: Incorporating a balanced diet rich in iron, zinc, biotin, and vitamins A, C, D, and E can promote hair health. Iron supplements, in particular, may be recommended for individuals with deficiencies.
- Hormone Regulation: In cases where telogen effluvium is triggered by hormonal changes, balancing hormones through medications or lifestyle changes can help stabilize the hair growth cycle.
2. Scalp Health Optimization
A healthy scalp is crucial for hair growth. Regular scalp massages, cleansing, and exfoliation can improve circulation and create a better environment for hair to regrow.
- Topical Treatments: Ingredients like caffeine, rosemary oil, peppermint oil, and minoxidil can stimulate blood flow to the scalp, promoting healthy follicle function.
- Gentle Hair Care: Avoiding harsh chemicals, sulfates, and excessive heat styling can protect the scalp and hair from additional stress.
3. Stress Management
Since telogen effluvium hair loss is often linked to emotional stress, implementing stress-relief techniques such as mindfulness, meditation, and regular physical exercise can reduce stress levels and positively impact hair growth.
4. Over-the-Counter and Prescription Treatments
For those experiencing telogen effluvium hair loss, over-the-counter and prescription treatments can offer additional support in managing hair loss and encouraging regrowth.
Minoxidil: Minoxidil, commonly known by the brand name Rogaine, is one of the most widely used over-the-counter treatments for hair loss. It’s an FDA-approved treatment for hair loss. It can be effective in some cases of telogen effluvium by prolonging the anagen phase of hair growth. Minoxidil works by prolonging the anagen (growth) phase of the hair cycle and stimulating blood flow to hair follicles, potentially speeding up regrowth in affected areas. Available in topical forms like solutions and foams, minoxidil is applied directly to the scalp, where it can take several months of consistent use to show visible results. Although minoxidil is not specifically designed for telogen effluvium, it can be beneficial for maintaining hair density during recovery.
Spironolactone: Another commonly prescribed medication is spironolactone, an anti-androgen that reduces the effects of excess androgens (hormones that can impact hair follicles) on hair growth. Spironolactone is sometimes prescribed off-label for telogen effluvium, particularly when the hair loss is influenced by hormonal imbalances. While spironolactone is commonly used in cases of androgenetic alopecia, it can be beneficial for telogen effluvium if hormonal fluctuations—such as those related to polycystic ovary syndrome (PCOS) or menopause—are exacerbating hair shedding. By blocking androgen receptors, spironolactone helps to limit hormone-related hair follicle stress, which may help stabilize hair shedding over time. However, it requires a prescription and monitoring from a healthcare provider, as it can have side effects and may not be suitable for everyone.
Low-Level Laser Therapy (LLLT): Non-pharmaceutical options like low-level laser therapy (LLLT) are another avenue for treating telogen effluvium. LLLT devices, such as laser combs, caps, or helmets, emit low-frequency light to stimulate hair follicles and encourage regrowth. Though the results vary, some users find that LLLT helps speed up recovery when used consistently. Laser therapy is generally safe and can be used alongside other treatments for added effectiveness. While it requires an upfront investment, many find it to be a useful tool to support scalp health and stimulate hair growth, especially when combined with other over-the-counter treatments.
For more intensive or prolonged cases, dermatologists may prescribe medications to help regulate the underlying causes of telogen effluvium. For example, if hormonal imbalances are contributing to hair loss, hormone therapy or oral contraceptives may be used to stabilize hormone levels and restore normal hair growth cycles.
Anti-inflammatory medications or corticosteroids may also be prescribed if scalp inflammation is exacerbating hair loss.
These treatments are typically tailored to each individual’s unique needs, making it crucial to consult a specialist for an accurate diagnosis and appropriate treatment plan.
Preventive Measures for Telogen Effluvium
While some causes of telogen effluvium are unavoidable, several preventive measures can reduce the risk of experiencing this type of hair loss:
- Maintain a Balanced Diet: Regular intake of essential vitamins and minerals can support overall hair health and resilience.
- Practice Gentle Hair Care: Avoid overly tight hairstyles, chemical treatments, and excessive use of heat tools that can weaken hair.
- Manage Stress: Engaging in stress-reducing practices such as exercise, yoga, or meditation can help maintain emotional well-being, which may prevent stress-related telogen effluvium.
- Monitor Medications: If you experience hair loss as a side effect of medication, consult your healthcare provider. They may be able to adjust your dosage or prescribe alternatives.
- Regular Scalp Care: Keeping your scalp clean, exfoliated, and well-nourished creates a healthy foundation for hair growth.
Timeline for Recovery and Regrowth
Recovery from telogen effluvium can vary depending on the individual and the severity of the hair loss. Generally, once the trigger is removed, hair should begin to regrow within 3–6 months. However, it may take up to a year or longer for hair to fully return to its original density. Patience and consistent care are essential during this time, as hair growth is a gradual process.
Conclusion: Telogen Effluvium Hair Loss
Telogen effluvium is a form of temporary hair loss that occurs when a large number of hair follicles enter the resting (telogen) phase prematurely, often due to stress, hormonal changes, or other triggers.
Telogen effluvium hair loss can be an overwhelming experience, but understanding its causes, symptoms, and treatments can empower you to take control of your hair health.
With appropriate care, a balanced diet, and attention to underlying triggers, most people can expect a full recovery. By prioritizing scalp health, managing stress, and addressing any nutritional deficiencies, you can support your hair’s natural growth cycle and prevent future occurrences of telogen effluvium.
