Abstract
BACKGROUND Hair serum is recommended therapy for the management of hair fall problems. People of all ages suffer from hair fall. AIM To evaluate safety and efficacy of hair growth promoting product in healthy adult subjects with hair fall complaints (Alopecia). METHODS In this safety and efficacy clinical study, 32 healthy individuals (aged 18-45 years) experiencing hair loss were enrolled. Participants applied 0.5 mL of the product to the affected scalp area daily for 60 days. The study evaluated various factors, including hair growth rate, thickness, density, scalp condition using CASLite-Nova, anagen-to-telogen ratio, hair fall reduction, overall hair and scalp appearance, hair strength, and participants' subjective perceptions of the product. RESULTS Highly statistically significant improvement was observed in hair growth rate, thickness, and density at Day 30 and Day 60. Hair growth rate increased (p-value <0.01) by 10.52% in 30 days and 31.62% in 60 days after test product application. Average hair growth increased by 424.21 μm/day and 487.31 μm/day at Day 30 and 60 respectively. The hair growth improved by up to 1.5 times after 60 days of usage in healthy subjects with hair fall complaints. No adverse events or product-related adverse events were reported. CONCLUSION Hair serum containing REGENDIL™ (Redensyl, AnaGain, Procapil, Capilia longa), and 5 kDa hyaluronic acid was efficacious and well tolerable in reducing hair fall (Alopecia). Hair serum significantly improved hair growth, hair density, hair thickness, and hair strength within 60 days of usage, thereby demonstrating it worth as a beneficial inclusion as a daily haircare product.

Abstract
Background Knowing normal values of scalp hair thickness and density is beneficial for diagnosing hair disorders, monitoring responses to therapy, performing hair transplants, and conducting relevant research. Such normal values have not yet been studied for Arabs. Objective To assess the hair density and diameter of the Arab population at different scalp sites using phototrichogram. Methods A cross-sectional descriptive study was performed at King Saud University Medical City from December 2021 to August 2022. The study was conducted on Arab adults who were not suffering from any hair disorder. The study was conducted using a questionnaire and clinical examination by phototrichogram. Results A total of 120 participants were enrolled in this study. The mean hair density was 147.1± 7.8 hairs/cm2, and the mean hair diameter was 87±4.9 μm. There were significant differences between hair density (P=0.0001) and diameter (P=0.0001) in different regions of the scalp. Females had higher hair density than males at occiput (P=0.038). Conclusion Arab hair has a higher thickness and lower density than hair of other ethnicities. This needs to be considered when diagnosing and/or treating hair problems in Arabs.

Abstract
Female pattern hair loss affects the central scalp, sparing the frontal hairline. The temporal area can also be affected by hair loss. We investigated the degree of temporal hair loss and correlation of other sites of scalp hair loss in Korean female pattern hair loss patients. A total of 109 women with female pattern hair loss were enrolled in this retrospective analysis. We measured hair density and thickness in five scalp sites including the frontal, vertex, occipital and bilateral temporal areas by phototrichogram. Frontal and vertex area hair loss were classified according to the Basic and Specific (BASP) classification, and temporal scalp and occiput areas were also assessed. Eighty-nine patients showed temporal hair loss. The mean of the hair density was lowest in the temporal area among all scalp areas. Total and thick hair densities of the frontal scalp were correlated with those of the vertex, temporal scalp and occiput in descending order, and hair thickness of the frontal scalp was more related with that of the temporal scalp than the vertex. In this study, temporal involvement is evident in female pattern hair loss. We suggest that temporal involvement should be added to pattern hair loss classification, especially BASP classification.

Abstract
OBJECTIVES To investigate the characteristics of hairs in Female pattern hair loss (FPHL) patients and healthy females in Southern China. MATERIALS AND METHODS Three fundamental hair parameters in different scalp areas of 90 Southern Chinese FPHL patients and 83 healthy controls were analyzed by phototrichogram. RESULTS Female pattern hair loss patients showed reduced hair density, hair diameter, and terminal/vellus hair ratio. The reduction correlated with the severity of Ludwig staging. Midscalp was the most affected area in FPHL, but occipital and temporal sites were also involved. In normal women, the highest hair density was observed in midscalp, followed by occipital and temporal areas. Peak hair density at midscalp sites was reached at 20s group, then declined with age. Maximum hair diameter at midscalp and occipital sites occurred in 40s group. Terminal/vellus hair ratio tended to increase with age and peak on 50-60s group. CONCLUSION Reduced hair density and hair diameter, and miniaturization of hair follicles are the characteristics of FPHL in Southern Chinese women. Occipital and temporal sites are also affected in FPHL. Age-associated changes might have an influence on the hair condition. The values of hair parameters obtained in this study will help to establish reference data for better evaluation of hair disorders.

Abstract
Purpose Female pattern hair loss (FPHL) is a common hair disease. However, studies of the quantitative measurement of FPHL are still limited. The aim of this study was to investigate the characteristics of hair density and hair diameter in normal women and FPHL patients, and further correlate the quantitative measurement with the clinical presentation of FPHL. Patients and methods An evaluation of 471 FPHL patients and 236 normal women was carried out according to the Ludwig classification, and analysis was performed by using a com-puterized handheld USB camera with computer-assisted software. Various areas of the scalp, including frontal, parietal, midscalp, and occipital, were analyzed for hair density, non-vellus hair diameter, and percentage of miniaturized hair. Results The hair density in normal women was the highest and the lowest in the midscalp and parietal areas, respectively. The FPHL group revealed the lowest hair density in the parietal area. Significant differences in hair density, non-vellus hair diameter, and percentage of miniaturized hair between the normal and FPHL groups were observed, especially in the midscalp and parietal areas. Conclusion The parietal area is another important affected area in FPHL in addition to the midscalp area. This finding provides novel important information of FPHL and will be useful for hair transplant surgeons choosing the optimal donor sites for hair transplantation in women.

Abstract
Introduction: Since skin and hair quality are potent vitality signals, and hair growth deficiency can cause significant psychological morbidity. In addition to clearly-defined hair loss disorders, milder forms of hair thinning or hair loss appear to be increasingly common, with a suggestion that sub-optimal diets and stressful lifestyles may be involved. Methods: Here we assess the value of a dietary marine-extract based dietary supplement in premenopausal women with subclinical hair thinning or hair loss conditions. This multi-site, randomized double-blind, placebo-controlled clinical trial was conducted with impact on hair shedding rate and hair fiber diameter (assessed by phototrichogram) as primary end points upon consumption of the oral supplement compared to a placebo. A total of 96 eligible female subjects were enrolled aged 21–55 years of age from Asian, Caucasian, and Hispanic ethnic backgrounds. Results: This study showed that hair shedding was significantly reduced in the first 3–6 months of daily consumption of the oral supplement. Moreover, phototrichogram image analysis revealed a statistically significant increase in the mean vellus-like hair diameter after 6 months of supplement consumption, when compared to the mean vellus-like hair diameters measured at baseline. Discussion: These results support the view that a nutritional supplement approach may be useful for women in this age group to deal with subclinical hair thinning or hair loss conditions, and those components of this marine extract-based oral supplement may be a useful adjunct.

Abstract
BACKGROUND The words "hair growth" frequently encompass many aspects other than just growth. OBJECTIVES Report on a validation method for precise non-invasive measurement of thickness together with linear hair growth rates of individual hair fibres. To verify the possible correlation between thickness and linear growth rate of scalp hair in male pattern hair loss as compared with healthy male controls. MATERIALS AND METHODS To document the process of validation of hair growth measurement from in vivo image capturing and manual processing, followed by computer assisted image analysis. We analysed 179 paired images obtained with the contrast-enhanced-phototrichogram method with exogen collection (CE-PTG-EC) in 13 healthy male controls and in 87 men with male pattern hair loss (MPHL). RESULTS There was a global positive correlation between thickness and growth rate (ANOVA; p<0.0001) and a statistically significantly (ANOVA; p<0.0005) slower growth rate in MPHL as compared with equally thick hairs from controls. Finally, the growth rate recorded in the more severe patterns was significantly (ANOVA; P ≤ 0.001) reduced compared with equally thick hair from less severely affected MPHL or controls subjects. CONCLUSION Reduced growth rate, together with thinning and shortening of the anagen phase duration in MPHL might contribute together to the global impression of decreased hair volume on the top of the head. Amongst other structural and functional parameters characterizing hair follicle regression, linear hair growth rate warrants further investigation, as it may be relevant in terms of self-perception of hair coverage, quantitative diagnosis and prognostic factor of the therapeutic response.
