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

Accessory Structures of the Skin: Hair Growth and Types

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...
Skin Diseases and Disorders01:23

Skin Diseases and Disorders

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...
Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
Healing II: Complications01:24

Healing II: Complications

Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
Prosopagnosia01:24

Prosopagnosia

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
Multipotency and Niche of Bulge Stem Cell01:06

Multipotency and Niche of Bulge Stem Cell

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...

    Summary
    This summary is machine-generated.

    Female pattern hair loss (FPHL) is not definitively linked to androgens. Diagnosis should utilize tools like dermoscopy and histopathology, rather than solely relying on hair loss patterns.

    Area of Science:

    • Dermatology
    • Trichology
    • Medical Diagnostics

    Background:

    • Female pattern hair loss (FPHL) has been historically equated with androgenetic alopecia.
    • The precise role of androgens in FPHL remains unproven, and its etiology is undefined.
    • Various hair loss patterns and scarring alopecias can mimic FPHL.

    Purpose of the Study:

    • To present FPHL as a distinct condition separate from androgenetic alopecia.
    • To advocate for diagnostic approaches beyond pattern recognition in female hair loss.
    • To highlight the utility of dermoscopy and histopathology in diagnosing alopecias.

    Main Methods:

    • Literature review and clinical discussion of FPHL.
    • Analysis of diagnostic criteria for female hair loss.
    • Emphasis on advanced diagnostic tools such as dermoscopy and histopathology.

    Main Results:

    • The etiological link between androgens and FPHL is not established.
    • Diagnostic reliance on hair loss patterns can be misleading in women.
    • Dermoscopy and histopathology offer valuable insights for accurate diagnosis.

    Conclusions:

    • FPHL should be considered independently of androgenetic alopecia.
    • A shift towards objective diagnostic methods is crucial for effective treatment of female alopecias.
    • Integrating dermoscopy and histopathology can improve clinical management of hair loss in women.
