Studysummary This study found that Turkish women with female pattern hair loss had significantly lower mid-scalp hair density and anagen ratio compared to healthy controls, with digital image analysis underestimating hair density.

In 2007, a study was conducted to quantify hair characteristics in Turkish women with female pattern hair loss (FPHL) and compare them with healthy volunteers. The study involved 39 patients with FPHL and 31 healthy volunteers. The results showed that the hair density and anagen hair ratio of the patients were significantly lower than those of the controls. The study also compared visual counting and digital image analysis methods for assessing hair density. It was found that digital image analysis underestimated hair density, especially in cases with higher hair density. Therefore, the study concluded that while diminished hair density is a key sign in diagnosing hair loss, digital image analysis may not be as effective as visual counting in detecting hair density.

research Phototrichogram Analysis of Japanese Female Subjects with Chronic Diffuse Hair Loss

25 citations , June 2003 in “Journal of Investigative Dermatology Symposium Proceedings”

This study found that among Japanese women with diffuse hair loss, decreased hair density without changes in vellus hair was the most common and distinct pattern observed, highlighting differences from previous observations in other populations.

research Methods of Evaluating Hair Growth

63 citations , February 2003 in “Australasian Journal of Dermatology”

This review discusses various methods for measuring scalp hair growth in androgenetic alopecia and reports no new results; the authors suggest that computer-assisted technology has untapped potential.

research Assessment of Hair Loss: Clinical Relevance of Hair Growth Evaluation Methods

41 citations , July 2002 in “Clinical and Experimental Dermatology”

This review evaluates hair growth measurement methods for human scalp hair, suggesting that combining highly resolutive analytical approaches with global calibrated methods is recommended for assessing hair changes in clinical settings.

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.

research Female Pattern Hair Loss
