Trichoscopic Patterns of Nonscarring Alopecia's

Area of Science:

• Dermatology
• Trichology

Background:

• Hair loss (alopecia) is a prevalent condition causing significant psychological distress.
• Early diagnosis and treatment are crucial for managing alopecia effectively.
• Trichoscopy offers a noninvasive approach for early diagnosis and monitoring of hair disorders.

Purpose of the Study:

• To conduct trichoscopy on patients with nonscarring alopecia.
• To document and analyze trichoscopic findings in nonscarring alopecia cases.

Main Methods:

• 100 patients with nonscarring alopecia were included.
• Physical examination, scalp, hair shaft, and root assessment were performed.
• Dermoscopy (trichoscopy) was utilized to examine lesions, with photographs taken for documentation.

Main Results:

• Alopecia areata (AA) and female pattern hair loss affected females equally (29.8%).
• Males were most frequently diagnosed with AA (41.8%).
• Common trichoscopic findings included broken hair (48%), black dots (48%), single hair follicle units (45%), short vellus hair (44%), upright hair (41%), and yellow dots (40%).

Conclusions:

• Trichoscopy reveals specific signs aiding in the identification of nonscarring alopecia.
• This technique plays a definitive role in diagnosing clinically challenging cases.
• Routine use of trichoscopy is recommended for examining nonscarring alopecia.
