Summary
Trichoscopy reveals characteristic patterns for diagnosing alopecia areata (AA). Key findings include yellow dots, black dots, broken hairs, short vellus hairs, and tapering hairs, aiding in diagnosis and treatment monitoring.
Area of Science:
- Dermatology
- Trichology
- Medical Diagnostics
Background:
- Alopecia areata (AA) incidence has risen globally.
- Trichoscopy is a crucial non-invasive diagnostic tool in dermatology for hair loss.
- Identifying characteristic trichoscopic patterns aids in AA diagnosis.
Conclusions:
- No single trichoscopic finding is pathognomonic for AA; a combination of findings is characteristic.
- Trichoscopy is valuable for monitoring treatment response in AA.
- Treatment response is indicated by increased short vellus hairs and decreased tapering hairs, broken hairs, and black dots; yellow dots show least responsiveness.

Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...
