This study found that trichorrhexis nodosa, a cause of unexplained hair loss, is often linked to mechanical trauma rather than a metabolic defect.

This study found that the distribution of mast cell prostaglandin d-synthase in the scalp spatially aligns with the pattern of androgenetic alopecia, suggesting a programmed vulnerability to hair loss.

In this study, researchers used three-dimensional reconstruction to show that the shape of the hair follicle determines the hair's form, with variations observed among different racial groups.

The technique effectively repairs skin after tumor removal, maintaining appearance and function without complications.

This study introduces Cell Journey, a new platform for visualizing RNA velocity in 3D, which aims to better capture complex cellular transitions in single-cell datasets compared to current 2D methods.

This review discusses the application of trichoscopy in diagnosing various hair and scalp diseases and reports no new clinical results; the authors emphasize its role as a non-invasive diagnostic tool.

This study revealed the complex three-dimensional innervation of touch domes in cat forepaw skin, highlighting the extensive branching and unmyelinated endings associated with Merkel cell–axon complexes.

This article outlines a method for achieving natural-looking hair direction and density in hair transplants using specific parting and incision techniques, without accelerating hair loss in the recipient area.

This study reviews the use of trichoscopy in diagnosing and monitoring alopecia areata, highlighting that certain trichoscopic findings like yellow and black dots, exclamation mark hairs, and others, provide valuable insights into disease status and treatment response.

In this report, a newborn female with bilateral symmetrical alopecia lesions was diagnosed with congenital triangular alopecia, an unusual presentation, highlighting the disorder's benign nature and the importance of early recognition and conservative management.

This report presents the first known case of a proliferating hybrid cyst containing both epidermoid and trichilemmal components on the scrotum of a 44-year-old man.

This article discusses distinguishing features of Diffuse Alopecia Areata and Fibrosing Alopecia in a Pattern Distribution, but reports no new clinical results.

This study found that the HairCheck® device, demonstrating high correlation between its Hair Mass Index and hair characteristics such as strand number and diameter, may be an effective tool for assessing hair mass changes in alopecia patients.

In this report, researchers describe a 13-month-old with neurodevelopmental disorder NEDESBA, confirming a TRAPPC4 gene mutation as the cause after excluding biotinidase deficiency, highlighting the importance of molecular testing for accurate diagnosis in overlapping metabolic and genetic conditions.

In this study, among Chinese infants and young children aged 0-5 years, Type II and Type III frontal hairline patterns were the most common, with a negative correlation observed between age and hairline type.

This study found that the culture conditions, not species-specific differences, determined whether sika deer dermal papilla cells adopted a 3D spheroidal or 2D monolayer growth pattern, influencing their hair-inducing ability.

This case report highlights the rare co-occurrence of Pili Annulati and Trichorrhexis Nodosa in a Syrian woman, underlining the need for further research into their relationship and treatment.

This article reviews various hair abnormalities observable through trichoscopy in conditions like monilethrix, trichorrhexis nodosa, and ectodermal dysplasias, with no new clinical findings reported.

This report describes a rare case of Trichostasis Spinulosa on the heel, an uncommon location for this type of lesion.

This study suggests that traditional classification systems for pattern hair loss, while useful in the past, have limitations in accuracy and reproducibility, and highlights the potential of integrating digital imaging and AI to create more precise and biologically informed classification frameworks.

This study found that the BASP classification system for pattern hair loss showed better reproducibility and repeatability compared to the Norwood-Hamilton classification.

Ingrown hairs are a common feature in scarring alopecias due to follicular damage.

This study found that trichoscopy can effectively differentiate scalp psoriasis from seborrheic dermatitis by identifying specific trichoscopic patterns such as hidden hairs, signet ring vessels, and comma vessels.

This study found that yellow dots were the most common trichoscopic finding in adult patients with alopecia areata, observed in 88.5% of cases.

In this study, empty follicular openings and pigtail hairs were more frequently observed in children with alopecia areata compared to adults, while yellow dots were less common in children.

This case report describes a 3-year-old male with X-linked ichthyosis and associated neurologic abnormalities, identifying an unusual cortical development malformation and suggesting that abnormal hair banding may assist diagnosis.

This study concluded that TrichoScan is error-prone in its current form and overestimates certain hair growth parameters, with results not aligning with clinical severity of alopecia.

This study found that female pattern hair loss was present in 12.5% of PCOS patients examined, with most cases in younger women, highlighting early detection and management importance.

This study reported that in women with pattern baldness, hormonal levels and iron deficiency were significantly associated with the condition, but trichoscopic findings were similar across different forms of female pattern hair loss.

This study found that certain trichoscopic features like white peripilar sign, yellow dots, and scalp pigmentation are positively correlated with the severity of androgenetic alopecia in Chinese patients.
