Understanding Telogen Effluvium: Causes, Symptoms, and Treatment

What is Telogen Effluvium?

Telogen Effluvium (TE) is a temporary form of hair loss that occurs when a significant number of hair follicles enter the telogen (resting) phase prematurely. This condition leads to excessive shedding and noticeable thinning of the hair. Unlike other forms of hair loss, TE is not permanent and is typically reversible with proper care and treatment.

Causes of Telogen Effluvium

TE is often triggered by a physical or emotional shock that disrupts the normal hair growth cycle. Some common causes include:

• Stress & Trauma – Emotional distress, major surgery, or accidents can push hair follicles into the resting phase.

• Hormonal Changes – Postpartum, menopause, or thyroid imbalances can contribute to TE.

• Nutritional Deficiencies – Low levels of iron, protein, zinc, or biotin may trigger excessive shedding.

• Medications – Certain drugs, including antidepressants, beta-blockers, and chemotherapy, can induce TE.

• Illness & Infections – Severe illnesses, fevers, and infections, including COVID-19, have been linked to TE.

• Harsh Hair Products – Some hair treatments, including certain shampoos and styling products, can cause scalp irritation leading to TE.

Symptoms of Telogen Effluvium

• Increased Hair Shedding – Noticeable hair loss while washing, brushing, or running fingers through hair.

• Overall Thinning – A general reduction in hair volume rather than patchy bald spots.

• Hair Falls Out Easily – Unlike breakage, TE-related hair loss occurs at the root.

• Scalp Sensitivity – Some people experience scalp tenderness or irritation.

Diagnosis

A dermatologist can diagnose TE through a scalp examination and by evaluating your health history, lifestyle, and recent stressors. In some cases, blood tests may be conducted to check for nutritional deficiencies or hormonal imbalances.

Treatment & Management

While TE is self-limiting and typically resolves within 3-6 months, taking the right steps can speed up recovery:

1. Address Underlying Causes

• If TE is caused by stress, work on relaxation techniques like meditation and yoga.

• Correct any nutritional deficiencies through a balanced diet or supplements.

• If medications are the culprit, consult your doctor about possible alternatives.

2. Scalp & Hair Care

• Use a gentle, sulfate-free shampoo to prevent further irritation.

• Incorporate Minoxidil (5%) – This FDA-approved topical treatment can stimulate hair regrowth.

• Ketoconazole Shampoo – Helps reduce inflammation and promotes scalp health.

• Alternate with Head & Shoulders to keep the scalp balanced and reduce shedding.

3. Healthy Lifestyle Habits

• Eat a Nutrient-Rich Diet – Focus on proteins, iron-rich foods, and essential fatty acids.

• Reduce Stress – Engage in activities that help manage anxiety.

• Stay Hydrated – Proper hydration supports healthy hair growth.

Prognosis: Will My Hair Grow Back?

Yes! Telogen Effluvium is temporary, and in most cases, hair will fully regrow within 6-12 months. However, consistent scalp care, a healthy lifestyle, and patience are essential for optimal recovery.

Final Thoughts

If you're struggling with sudden hair loss, you’re not alone. Identifying the cause and following a proper hair care routine can significantly aid recovery. Always consult with a dermatologist to create a personalized treatment plan for the best results.
