Research cited in this study

10 / 10 results

research Scalp Dermoscopy or Trichoscopy

69 citations , January 2015 in “Current problems in dermatology”

This review discusses trichoscopy as a noninvasive, effective technique for diagnosing various hair loss conditions and monitoring treatment, highlighting its potential to reduce scalp biopsy necessity.

research Dermoscopy Evaluation of Skin in Healthy Cats

19 citations , October 2014 in “Veterinary Dermatology”

Dermoscopy is a good, noninvasive way to see normal cat skin structures and could be useful for check-ups.

research Histological and Dermatoscopic Description of Sphynx Cat Skin

26 citations , August 2014 in “Veterinary Dermatology”

This study found that sphynx cats exhibit hair follicle dysplasia with abnormal hair shaft production, but without a reduction in the number of follicles, similar to murine KRT 71 mutants.

research Dermatoscopy of Hair Shaft Disorders

68 citations , August 2012 in “Journal of the American Academy of Dermatology”

This paper discusses the use of dermatoscopy as a fast, noninvasive technique for diagnosing hair shaft disorders and reports no new results; the authors highlight its advantages over traditional microscopy methods.

research Hair and Scalp Dermatoscopy

245 citations , March 2012 in “Journal of The American Academy of Dermatology”

This review discusses the dermoscopic features of common hair and scalp disorders and reports no new clinical results, aiming to assist dermatologists in diagnosing conditions like tinea capitis and alopecia areata.

research Coudability Hairs: A Revisited Sign of Alopecia Areata Assessed by Trichoscopy

56 citations , June 2010 in “Clinical and experimental dermatology”

In this study, coudability hairs were identified as a useful marker for assessing disease activity in patients with alopecia areata and may serve as an alternative to the hair-pull test.

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 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 Circle Hairs Are Not Rolled Hairs

20 citations , October 1996 in “Journal of the American Academy of Dermatology”

research Diagnostic and Predictive Value of Horizontal Sections of Scalp Biopsy Specimens in Male Pattern Androgenetic Alopecia

309 citations , May 1993 in “Journal of The American Academy of Dermatology”

This study concluded that horizontal sections of scalp biopsy specimens provide more diagnostic information for male pattern androgenetic alopecia than vertical sections and can predict hair regrowth potential following topical minoxidil therapy.
