Accessory Structures of the Skin: Hair Growth and Types

1.9K
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...

Multipotency and Niche of Bulge Stem Cell

3.9K
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.

Diagnosing acute telogen effluvium can be difficult, but observing hair regrowth in specific areas like the frontal fringe can aid diagnosis. This study proposes a diagnostic triad for resolving telogen effluvium.

Area of Science:

  • Dermatology
  • Trichology

Background:

  • Acute telogen effluvium diagnosis can be challenging, particularly after the active shedding phase when the pull test may be negative.
  • Differential diagnoses include alopecia areata and traction alopecia, requiring careful clinical evaluation.

Observation:

  • The study observed five cases of telogen effluvium in resolution, noting hair regrowth in frontal, bitemporal, and occipital areas.
  • Frontal and temporal regions showed a higher density of telogen hairs and were more impacted during the active phase.
  • Hair behavior in the occipital area appeared similar to other affected regions.

Findings:

  • Clinical signs of hair regrowth are crucial for diagnosing resolving telogen effluvium.
  • The proposed "acute telogen effluvium triad" during resolution includes frontal fringe, temporal recess, and occipital fringe regrowth.
  • This triad can assist clinicians in identifying telogen effluvium when traditional diagnostic methods are inconclusive.

Implications:

  • The proposed diagnostic triad offers a practical approach for identifying telogen effluvium during its resolution phase.
  • Improved diagnostic criteria can lead to more accurate and timely patient management.
  • Further research can validate the proposed triad and explore its application in diverse patient populations.
