research Trichoscopy for Common Hair Loss Diseases: Algorithmic Method for Diagnosis

89 citations , December 2010 in “The Journal of Dermatology”

This study describes characteristic trichoscopic features of various hair loss diseases and proposes an algorithmic method for diagnosing them, but reports no new clinical results.

research Pinpoint White Dots in the Scalp: Dermoscopic and Histopathologic Correlation

60 citations , September 2010 in “Journal of the American Academy of Dermatology”

Small white dots on the scalp seen with a dermoscope correspond to sweat ducts and vary with different hair disorders.

research Scalp Dermoscopy of Androgenetic Alopecia in Asian People

67 citations , February 2009 in “Journal of Dermatology”

This study found that dermoscopy can be a useful tool for diagnosing androgenetic alopecia, particularly in determining hair diameter diversity as an essential feature in Asian populations.

research Dermoscopy in Female Androgenic Alopecia: Method Standardization and Diagnostic Criteria

129 citations , January 2009 in “International Journal of Trichology”

This study found that trichoscopy criteria can distinguish female androgenic alopecia from chronic telogen effluvium, with specific features achieving 98% diagnostic specificity.

research What Is Normal Hair? Advancements in Hair Imaging Techniques

1 citations , July 2008 in “Expert Review of Dermatology”

Normal hair thickness varies by scalp area and a mix of hair thicknesses is typical in healthy individuals.

research Clinical Significance of Dermoscopy in Alopecia Areata: Analysis of 300 Cases

196 citations , June 2008 in “International Journal of Dermatology”

This study found that dermoscopic indicators like black dots and tapering hairs are valuable markers for diagnosing and assessing the severity and activity of alopecia areata in Asian patients.

research The Role of Scalp Dermoscopy in the Diagnosis of Alopecia Areata Incognita

150 citations , April 2008 in “Journal of The American Academy of Dermatology”

This study found that videodermoscopy reveals distinct dermoscopic features in patients with alopecia areata incognita, aiding in biopsy decisions by identifying the appropriate sampling area and potentially avoiding unnecessary procedures.

research Significance of Dermoscopy in Acute Diffuse and Total Alopecia of the Female Scalp: Review of Twenty Cases

42 citations , January 2008 in “Dermatology”

This study reports that dermoscopy is a useful diagnostic tool for distinguishing acute diffuse and total alopecia of the female scalp from female pattern hair loss by identifying specific hair features.

research Videodermoscopy in the Evaluation of Hair and Scalp Disorders

304 citations , July 2006 in “Journal of The American Academy of Dermatology”

This study found that videodermoscopy enhances diagnostic accuracy for scalp and hair disorders beyond simple clinical inspection and reveals novel disease features that could improve clinical understanding.

research Histological Features of Peripilar Signs Associated with Androgenetic Alopecia

95 citations , January 2004 in “Archives of Dermatological Research”

This study found that peripilar signs on the scalp are linked to perifollicular lymphocytic infiltrates in early androgenetic alopecia, detectable even in areas with high hair density.

research Kenogen

90 citations , January 2002 in “Dermatology”

This study describes the kenogen phase, where hair follicles rest after shedding, and finds its duration and frequency are greater in individuals with androgenetic alopecia, potentially contributing to baldness.
