Diagnosis and Treatment of Telogen Effluvium (Seasonal Hair Loss)
Telogen Effluvium is a type of hair loss that occurs when an imbalance in the hair cycle causes an excessive number of hairs to enter the resting (telogen) phase. It is usually a temporary and widespread form of hair loss. Many factors, such as stress, illness, and seasonal changes, can trigger this condition.
Causes and Risk Factors of Telogen Effluvium
1. Stress: Severe psychological stress can trigger hair loss.
2. Hormonal Changes: Can be observed after pregnancy, discontinuation of birth control pills, or during menopause.
3. Nutritional Deficiencies: Deficiencies in iron, zinc, vitamin B12, etc.
4. Seasonal Changes: Seasonal shedding is common, especially in the fall and spring.
5. Illnesses and Surgeries: Viral infections like COVID-19, surgeries, or chronic illnesses.
6. Medication Use: Hair loss can occur after taking antihypertensives, antidepressants, or chemotherapy.
7. Diet and Rapid Weight Loss: Sudden changes in weight can increase hair loss.
Symptoms
- Widespread Hair Loss: Excessive hair shedding is particularly noticeable when washing or brushing hair.
- Thinning Hair: The overall density of hair decreases due to widespread shedding.
- No Skin Lesions or Marks: The scalp appears healthy, with no visible sores or redness.
- Sudden Onset: Shedding typically begins 2-3 months after a triggering event.
Diagnostic Methods
1. Clinical Examination: A dermatologist assesses the extent and type of hair loss.
2. Hair Pull Test: Lightly pulling on the hair determines the intensity of hair loss.
3. Dermatoscopy and Trichoscopy: Microscopic examination of hair follicles.
4. Blood Tests: Evaluation for iron deficiency, thyroid dysfunction, and vitamin deficiencies.
5. Hair Biopsy: In rare cases, samples may be taken from hair follicles.

3. Natural and Supportive Treatments
