Resumen
El encanecimiento del cabello, un signo natural del envejecimiento, puede causar angustia psicológica. La investigación actual explora sus causas, pero los tratamientos eficaces para el encanecimiento prematuro siguen siendo limitados, lo que afecta la autoestima.
Área de la Ciencia:
- Dermatología
- Investigación sobre el envejecimiento
- Biología Molecular
Sus antecedentes:
- El encanecimiento del cabello (canas) es un signo común de envejecimiento debido a la pérdida de melanina en los folículos pilosos.
- El encanecimiento prematuro impacta significativamente el bienestar psicológico y la autoestima.
- Las causas precisas del encanecimiento del cabello no se comprenden completamente.
Objetivo del estudio:
- Resumir la comprensión actual de la patogénesis del encanecimiento del cabello.
- Destacar los factores que contribuyen al encanecimiento prematuro.
- Discutir las limitaciones en las opciones de tratamiento actuales.
Principales métodos:
- Revisión de la literatura científica existente sobre el encanecimiento del cabello.
- Análisis de los factores implicados en la producción de melanina y el envejecimiento de los folículos pilosos.
- Evaluación de las estrategias terapéuticas actuales y su eficacia.
Principales resultados:
- El encanecimiento del cabello está relacionado con el estrés oxidativo, la radiación UV, la genética y los factores del estilo de vida.
- La reducción de la producción de melanina por los melanocitos en el bulbo piloso es el mecanismo principal.
- Son escasos los tratamientos eficaces y basados en la evidencia para revertir o prevenir el encanecimiento.
Conclusiones:
- El encanecimiento del cabello es un proceso multifactorial con importantes implicaciones psicosociales.
- Se necesita más investigación sobre la patogénesis para desarrollar intervenciones eficaces.
- Las soluciones cosméticas son actualmente el enfoque más común para controlar el cabello canoso.

01:20Accessory Structures of the Skin: Hair Growth and Types
2.2K
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...

01:19The Effect of Aging on Tissues
3.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:06Multipotency and Niche of Bulge Stem Cell
4.1K
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...

01:22Hair Cells
44.2K
Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.

01:16Accessory Structures of the Skin: Hair and Hair Follicles
4.2K
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...

01:14Changes in Skin Color: Clinical Perspectives
3.2K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...
