“…Hair density in this study showed a similar value to the previous study in Southern Chinese women (15). However, when comparing with other studies on Asian women including Korean and Thai women, the hair density of Chinese normal participants was a little bit lower and much lower than Caucasians, Hispanics and Africans (13,(27)(28)(29). In terms of hair shaft diameter, our results also seemed to be much "lower" than other similar studies except for the study of Caucasians women conducted by Rakowska et al (9).…”

“…The variation of the results in different studies may be caused by different devices and manners for the studies. Most of the previous study included about five randomly selected terminal hairs for hair shaft diameter measurement under 100-fold magnification, using trichoscopy system Folliscope R (LeedM Corporation) (13,28). While in our study and Rakowska et al (9) study, vellus hair was also included in the diameter measurement.…”

Objectives: To investigate the trichoscopic features of female pattern hair loss (FPHL) in Chinese Han patients and analyze the difference between male and female patients with FPHL.Materials and Methods: Trichoscopic images were taken in four different scalp areas, including right frontal hairline, vertex, right parietal and occipital areas. Hair density, hair shaft diameter, vellus hair ratio and single hair follicle unit ratio were counted manually and analyzed.Results: Seventy-three subjects were enrolled in this study, including 38 patients with FPHL (28 females and 10 males) and 35 normal controls without hair loss. The hair density and hair shaft diameter of FPHL patients reduced in the whole scalp. Vellus hair ratio and single hair follicle unit ratio were both increased in FPHL compared to normal controls. The vertex was the most affected area and the hair shaft diameter showed the most significant difference. Parietal and occipital area were also affected in FPHL. The reduction or increase was correlated with the severity of Ludwig staging. Very few gender differences were detected in male and female FPHL patients.Conclusion: FPHL patients showed decreased hair density and hair shaft diameter, accompanied by increased vellus hair ratio and single hair follicle unit ratio. Parietal and occipital area can be also affected in FPHL, though not as severe as in vertex area. FPHL in male basically has the same characteristic as those in female patients.Limitation: The main limitation of the study is the small sample size which only enrolled 10 male FPHL patients, in comparison to the female cases. The findings could not be representative of the normal population with the limited sample size.

“…The temporal involvement in this study is evident in female hair loss. We propose that temporal involvement should be added to the pattern hair loss classification, especially the BASP classification 29 . As a result of applying scalp massage for 15 and 25 min to female office workers, positive effects were observed on stress hormones, blood pressure, and heart rate.…”

Aims The purpose of this paper was to review the literature focusing on the scalp health of the Korean people in the COVID‐19 Blue era and the possibility of significant development as an academic Methods This review paper is a literature review, and the method is a narrative review. Results It was found that the higher the awareness of hair loss, the better the scalp and hair management behavior. South Korea needs to develop systematic customized management methods, scalp programs and products due to the development of the COVID‐19 era and the development of the 4th industry. Conclusion South Korea still needs dto improve the expertise of tricolologists and national social security insurance and research along with the growth of the beauty and healthcare service industry in the COVID‐19 Blue era.

“…and parietal scalp is of neural crest origin, while that of the occipital scalp is of mesodermal origin. 24,25 Follicular units from different regions of the scalp vary in their susceptibility to undergo terminal to vellus hair transformation, leading to macroscopic and microscopic patterns of hair loss, respectively. 26 In our observation, there were a small quantity of FPHL patients who presented with serious hair loss in the parietal area.…”

Background Female pattern hair loss (FPHL) is the most common hair loss disorder in women, which may impair patient’s self-identity. It presents as a diffuse reduction in hair density at the mid and frontal regions of the scalp with preservation of the frontal hairline. TrichoScan can be used as a diagnostic tool and for monitoring patients in male pattern hair loss, but little is known in FPHL with Chinese population. Objective To explore the predictive value of various TrichoScan characteristics at different areas of the scalp in the diagnosis and evaluation of FPHL. Materials and Methods A total of 261 FPHL subjects were divided into three groups according to Ludwig classification. Together with 108 healthy controls, they were evaluated by computer-assisted TrichoScan. Various hair parameters were analyzed in the frontal, midscalp, vertex, parietal, and occipital areas of the scalp. Results Declining hair densities, terminal hair percentage, hair follicular unit density, mean hair diameter, and average hair/unit combined with increased intermediate hair percentage, and vellus hair percentage were observed across all areas of the scalp for FPHL subjects. Hair density and terminal hair percentage in the midscalp area were the factors most affecting Ludwig classification. The two parameters combined achieved 85.12% correct classification rate and an area under the ROC curve of 0.88 in the diagnosis of FPHL. Additionally, we reported a unique type of FPHL which mostly affected the parietal area, occurring with or without traditional midline changes. Conclusion FPHL in a Chinese population presented characteristics of reduced hair density and miniaturization of hair follicles in the midline scalp and to a lesser extent in the parietal area. Hair density and terminal hair percentage in the midscalp exhibited the greatest predictive value of Ludwig classification. Our results may further provide the basis for quantitative classification of FPHL.
