Telogen effluvium: a comprehensive review.

Area of Science:

• Dermatology
• Trichology

Background:

• Excessive hair shedding, known as telogen effluvium (TE), is a frequent concern, particularly among women.
• TE presents diagnostic and classification challenges, often co-occurring with androgenetic alopecia (AGA).

Purpose of the Study:

• To address key issues in diagnosing and managing telogen effluvium.
• To clarify diagnostic criteria, classification, and differentiation from other hair loss conditions.
• To highlight the importance of patient-centered care in managing TE.

Main Methods:

• Review of diagnostic criteria for TE.
• Discussion of classification systems for hair shedding disorders.
• Analysis of the relationship between TE and androgenetic alopecia (AGA).
• Evaluation of trichodynia as a symptom.
• Assessment of histopathology findings in TE.
• Outline of management strategies from diagnosis to treatment.

Main Results:

• Defines criteria for diagnosing the severity of hair loss in TE.
• Highlights the heterogeneity of TE and the need for classification.
• Differentiates TE from androgenetic alopecia (AGA).
• Discusses the diagnostic value and frequency of trichodynia.
• Explains the nonspecific nature of histopathology in TE diagnosis.
• Provides a comprehensive overview of TE management.

Conclusions:

• Accurate diagnosis and classification of TE are crucial.
• Distinguishing TE from AGA is essential for appropriate treatment.
• Management requires a thorough approach, considering patient impact and empathy.
• Dermatologists should validate patient concerns regarding hair loss.
