Hair Loss: Diagnosis and Treatment

Area of Science:

• Dermatology
• Trichology

Background:

• Hair loss, or alopecia, impacts over 80 million individuals in the United States.
• Alopecia encompasses various forms, including nonscarring types like diffuse, patterned, and focal hair loss.

Purpose of the Study:

• To categorize different types of alopecia and their associated causes.
• To outline current treatment strategies for various forms of hair loss.
• To emphasize the psychological impact and importance of patient education in managing alopecia.

Main Methods:

• Review of current medical literature on alopecia.
• Classification of nonscarring alopecias into diffuse, patterned, and focal categories.
• Discussion of diagnostic approaches including history, physical examination, and laboratory testing.

Main Results:

• Diffuse alopecias (telogen and anagen effluvium) are often self-limited.
• Patterned hair loss, primarily androgenetic alopecia, is common and treatable with minoxidil or finasteride (for males).
• Focal hair loss includes alopecia areata, tinea capitis, and traction alopecia, each with specific treatments.

Conclusions:

• Systemic diseases can cause hair loss, necessitating thorough medical evaluation.
• Moderate to severe alopecia is linked to psychological distress and reduced quality of life.
• Effective patient education on hair changes, treatments, and outcomes is crucial for managing alopecia.
