Summary
Trichoscopy reveals key indicators of androgenetic alopecia (AGA), such as increased yellow dots and single-hair units. This imaging technique aids in monitoring AGA progression and treatment effectiveness.
Area of Science:
- Dermatology
- Trichology
Background:
- Androgenetic alopecia (AGA) is a common condition causing progressive hair loss in genetically susceptible individuals.
- Trichoscopy, or scalp dermoscopy, visualizes hair structures and scalp microvasculature.
Purpose of the Study:
- To identify characteristic trichoscopic features of androgenetic alopecia.
Main Methods:
- A prospective study compared 104 patients with AGA to 80 healthy controls.
- Trichoscopic examination assessed hair shafts, follicle openings, and perifollicular changes in different scalp areas.
- Key metrics included yellow dots, vellus hairs, single-hair units, and perifollicular hyperpigmentation.
Main Results:
- Patients with AGA showed significantly higher numbers of yellow dots and single-hair pilosebaceous units compared to controls.
- A significantly greater percentage of thin hairs (<0.03 mm) was observed in the AGA group.
- Increased perifollicular hyperpigmentation was also noted in AGA patients.
Conclusions:
- Trichoscopy is a valuable tool for diagnosing and assessing androgenetic alopecia.
- Regular trichoscopic monitoring is crucial for tracking disease activity and treatment response in AGA patients.

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...

A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

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...
