This study confirmed significant and dramatic ophthalmic and mucocutaneous sequelae from Stevens-Johnson and Lyell syndromes in Morocco, affecting the social and professional integration of mostly young patients.

In this study conducted among healthy Iranian girls in Isfahan province, researchers found that the median onset age for menstruation was 12.05 years, breast development began at 9.89 years, and pubic hair development started at 10.14 years, with earlier puberty onset potentially indicating precocious puberty.

Finasteride and dutasteride do not significantly change beard thickness in men.

This study found that acne lesion formation involves early hyperkeratinization and inflammation around hair follicles, creating a self-sustaining cycle that may progressively worsen acne.

In this study, the researchers measured the specific density and dielectric permeability of human hair by analyzing the attenuation of millimeter radiowaves and accounting for multiple reflections within the hair layer.

This review discusses the use of trichoscopy for diagnosing alopecia and reports no new clinical results, emphasizing its role in identifying vascular and follicular features.

This study introduced a novel, weakly supervised method for segmenting hair in Scanning Electron Microscope images using simple image-level annotations, achieving over 30% improvement in mean Hausdorff Distance compared to Unet and SAM, while enhancing interpretability and refinement.

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

This review discusses how hair follicle light sensitivity is linked to mesenchymal remodeling and suggests that this connection influences photoepilation outcomes and optimal treatment strategies, reporting no new clinical results.

This study introduces a spherical skin model that effectively mimics key features of human skin, offering a scalable and rapid alternative for non-animal dermatological and cosmetic testing.

This report discusses a case of reticular erythematous mucinosis syndrome, highlighting minimal mucin deposition and significant lymphocytic infiltration around the hair follicle, contributing to the ongoing debate about its nature as a mucinosis.

This abstract describes the Dermatologic Surgery journal's extensive focus on skin surgery procedures, but it presents no new research findings.

In this study, LC-OCT imaging was found to noninvasively identify specific features of cicatricial alopecia due to lupus erythematosus, such as hyperreflective collagen fibers, which may aid in distinguishing it from other types of scarring alopecia.

This case report describes a strong dermoscopic and histopathological correlation in lichen nitidus, helping differentiate it from other similar conditions.

This review highlights the potential of near-infrared light therapy to improve metabolic, antioxidant, and cognitive functions without adverse effects, and supports its use for visual and neurological conditions through molecular and cellular mechanisms, as reported in this source.

The 1540nm fractional erbium-glass laser helps treat hair loss caused by hormones.

This study suggests that establishing international consensus guidelines for including concealed or sensitive sites in routine forensic examinations is crucial to clarify clinician responsibilities, guide patient expectations, and reduce potential medicolegal issues.

This article discusses the importance of integrating clinical observations with laboratory research, emphasizing the need for clinicians to collaborate with researchers to address medical problems.

This report describes the sonographic characteristics of a proliferating trichilemmal tumor in the subungual region, identifying it as a heterogeneous mass with echogenic foci, potentially representing keratin and cholesterol.

This case report details a 37-year-old woman with pityriasis rubra pilaris, highlighting scarring alopecia and widespread hyperkeratotic lesions despite various treatments.

This study is the first to describe a mixed pattern of essential syphilitic alopecia using trichoscopy, identifying features like tapered bended hairs and perifollicular hyperkeratosis in a patient without secondary syphilis symptoms.

This study found that after topical application in rats, 1,24-dihydroxyvitamin D3 absorbed through both the stratum corneum and hair follicles, with about 30% excreted via the faeces.

A simple method can show hair's surface pattern.

This systematic review found that licensed hair gloss products in the UK provide significant cosmetic benefits like improved shine and smoothness, but 18% contain harmful additives, highlighting the need for stricter regulations and patient education on product safety.

This case report suggests that intralesional cidofovir may be a consideration for treating squamous cell carcinoma, as it showed a successful outcome without systemic toxicity, although surgical excision remains preferred.

In this study, patients with systemic lupus erythematosus and generalized non-scarring alopecia exhibited hair loss similar to telogen effluvium, with significant changes observed in the cuticle of telogen hairs.
