Accessory Structures of the Skin: Hair Growth and Types01:20

Accessory Structures of the Skin: Hair Growth and Types

1.5K
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...

Accessory Structures of the Skin: Hair and Hair Follicles

2.5K
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...

Multipotency and Niche of Bulge Stem Cell

3.8K
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...

Skin Diseases and Disorders

4.0K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Papillary Dermis

3.2K
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Summary

Trichoscopy aids in diagnosing alopecia areata, an autoimmune hair loss condition. Specific findings like yellow dots indicate poor treatment response, while their disappearance suggests improvement.

Area of Science:

  • Dermatology
  • Autoimmune Diseases

Background:

  • Alopecia areata is an autoimmune condition causing patchy hair loss.
  • Clinical diagnosis is standard, but adjunct methods can improve accuracy and monitoring.

Purpose of the Study:

  • To review the utility of trichoscopy in diagnosing and monitoring alopecia areata.
  • To identify key trichoscopic features associated with the disease and treatment response.

Main Methods:

  • Review of existing literature on trichoscopy in alopecia areata.
  • Analysis of common and less common trichoscopic findings.

Main Results:

  • Common findings include yellow dots, black dots, exclamation mark hairs, short vellus hairs, and coudability hairs.
  • Disappearance of black dots, broken hairs, and exclamation mark hairs indicates treatment success.
  • Persistent yellow dots suggest chronic disease and poor treatment outcomes.

Conclusions:

  • Trichoscopy is a valuable, non-invasive tool for diagnosing alopecia areata.
  • Specific trichoscopic features correlate with disease activity and treatment efficacy, aiding patient management.
