This study found that topical valproic acid significantly increased hair count in male patients with moderate androgenetic alopecia compared to placebo over 24 weeks.

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.

In this study, researchers characterized the normal scalp hair properties in South Koreans, observing that hair density declined with age and varied across scalp sites, while hair thickness patterns remained relatively stable until later in life.

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

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.

Finasteride 1 mg/day effectively treats hair loss in men aged 18-41 and over 41; DEET lotion works better than herbal insect repellents; combined tattoo removal technique shows no extra benefits.

Applying valproic acid on the scalp increased hair growth in men with 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.

In this study, Scalp Immersion Proxigraphy (SIP) was shown to produce more accurate measurements of linear hair growth rate than crude phototrichogram techniques, suggesting SIP's suitability for clinical trials monitoring hair growth.

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.

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 commentary reviews the findings of a study on platelet-rich plasma therapy for female androgenetic alopecia and suggests further evaluation of its quantitative effectiveness despite promising preliminary results.

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.

Minoxidil helps increase hair growth and density in people with hair loss, with higher concentrations giving better results.

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.

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.

The study reported a significant genotype–phenotype correlation in prepubescent males with XLHED, particularly in the severity of skin and hair manifestations between those with different EDA mutations.

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 paper reviews hair loss associated with various endocrine disorders and describes both traditional and emerging non-invasive diagnostic methods without presenting any new clinical results.

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 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 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.

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

In a study involving adults with mild to moderate dandruff, researchers observed that post-hair wash interventions significantly reduced dandruff as measured by three assessment methods, showing substantial reliability and correlation, which supports their use in clinical settings for evaluating scalp dandruff treatments.

In this case report, a 16-year-old girl with adolescent androgenetic alopecia showed visible improvement in hair density after 2 years of treatment with 3% topical minoxidil, despite a family history of the condition and normal hormone levels.

In this study, a DMG-Na and caffeine-containing shampoo significantly reduced hair loss and increased hair density in men with male pattern hair loss over 6 months, compared to a placebo, without adverse effects.

In this article, two patients with mild to moderate androgenetic alopecia showed improved hair density and reduced vellus hairs after treatment with exosome-derived solutions from salmon tissues, suggesting potential benefits of this approach.

This study found that after a 4-month comprehensive therapy course, 90.5% of patients with androgenetic alopecia and telogen effluvium showed hair condition improvement, highlighting the potential benefits of adjuvant proteoglycan replacement therapy in these conditions.
