This study developed a novel system that can automatically estimate hair loss parameters from images without expert input, reporting satisfactory results from testing on samples collected in Kolkata.

This study found that low ferritin levels are associated with higher telogen ratios in women with diffuse hair loss, suggesting an important role of ferritin in telogen effluvium diagnosis.

In this study, hemoglobin levels were the only marker positively correlated with anagen hair ratios in patients with telogen effluvium, suggesting it may be a cost-effective initial test for management.

This study assessed the effects of a formulation containing millet extract, wheat germ oil, L-cystine, and calcium pantothenate on women with telogen effluvium using Digital Phototrichogram, but it reports no new results.

This study found that topical melatonin significantly improved hair density and reduced the severity of androgenetic alopecia in men and women.

This article reviews the diagnosis and causes of different types of alopecia, presenting no new clinical findings.

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.

This study found that photoepilation using intense pulsed light significantly reduced hair growth parameters, and phototrichograms may offer an objective method to evaluate its effectiveness.

This study found that in women with androgenetic alopecia, hair density is lower, and thin and non-growing hair are more common on the midscalp compared to the occiput.

This study found that a commercially available shampoo significantly increased hair counts and reduced hair shedding in Korean subjects with alopecia over 16 weeks.

This study developed a high-resolution phototrichogram system that can automatically and accurately assess hair growth metrics in cosmetic trials, achieving over 90% correlation with manual measurements.

In this study, Arab hair was found to have a higher thickness and lower density compared to other ethnicities, suggesting these factors should be considered in diagnosing and treating hair issues in Arabs.

This study observed that hair density and thickness were significantly reduced across multiple scalp sites in South Korean women with hair loss, highlighting potential patterns that could aid in differentiating hair disorders.

People with X-linked hypohidrotic ectodermal dysplasia have no sweat ducts and less, thinner hair.

In this study, reduced hair density, diameter, and follicle miniaturization were key characteristics of female pattern hair loss in Southern Chinese women, with occipital and temporal sites also affected.

In this clinical study, researchers observed that a shampoo formulated with Inula helenium and Caesalpinia Sappan extracts significantly increased total hair count after 16 and 24 weeks in patients with androgenetic alopecia, suggesting it may help prevent hair loss and promote hair growth.

This study found that measuring hair thickness with a phototrichogram provided significantly thicker readings than using a micrometer caliper, suggesting that the phototrichogram may be more clinically useful for evaluating hair in patients undergoing hair transplantation.

The document concludes that using a phototrichogram with a protractor and tapeline is a reliable and noninvasive way to measure hair loss.

This study found that females with androgenic alopecia experienced greater improvements in hair density after cosmetic treatments compared to males, in a cohort stratified by age and gender.

This study found that contrast enhanced phototrichogram (CE-PTG) significantly improved detection of various hair types and growth stages in androgenetic alopecia compared to standard PTG and was comparable to biopsy analysis.

In this study, female patients undergoing hormone replacement therapy showed improvements in frontal hairline appearance and increased hair plucking strength, suggesting positive effects of estradiol on hair growth while excluding age-related factors.

This exploratory pilot study reported that using a 2% Oleosome-FGF-2 fusion extract scalp serum twice daily for 84 days in women with telogen effluvium and brittle hair improved hair density, anagen/telogen ratio, hair shaft thickness, and scalp hydration compared to a placebo.

This study reports that Broussonetia papyrifera extract significantly increased hair count over 12 weeks in a small clinical trial and promoted dermal papilla cell proliferation in vitro by regulating WNT-β-catenin and STAT6 pathways.

This review discusses the advantages and limitations of various hair loss evaluation methods but reports no new results; it emphasizes the importance of cautious interpretation for these diagnostic tools.

This study reported that Trichoscan, a computer-assisted hair measurement system, was not supported as accurate for clinical trials due to errors in signal detection, despite its analysis speed.

This study suggests that dutasteride may be a viable alternative for Korean men with androgenetic alopecia who do not respond to finasteride, as it improved hair density and thickness in most participants.

This article discusses various mechanisms for promoting hair growth in pattern hair loss and highlights the challenge of balancing short-term measurable results in trials with the need for long-term efficacy data.

This article reviews various diagnostic tools for hair disorders, describing methods ranging from invasive to noninvasive, but reports no new research findings or clinical results.

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.
