Researchers found a new area on chromosome 2 linked to a genetic hair loss condition.

This study found considerable variation in hair shaft proteomic profiles among Caucasian, African-American, Kenyan, and Korean subjects, with individual and site-specific differences observed.

This study used proteomic profiling to reveal significant individual and site-specific differences in human hair shaft proteins, which may improve the differentiation of hair based on ethnic origin and individual identity.

This study found that a decrease in estradiol levels in women is associated with increased hair shedding due to weakened anchoring of telogen hairs.

This article reviews the structure, genomic organization, and pathogenesis of SARS-CoV-2 and discusses current efforts in prevention and treatments for COVID-19 without reporting new clinical results.

This study introduced the Lichen Planus Activity and Damage Index (LiPADI), which effectively assesses the severity and progression of lichen planus, aligning well with other clinical indicators.

This case report describes a 59-year-old Afro-American woman diagnosed with lipedematous alopecia, a rare scalp condition of unknown cause.

This article reviews the role of liposomes in dermatology and does not report new clinical results.

This article reviews lip reconstruction techniques after Mohs surgery, presenting an algorithm to aid decision-making based on defect location and tissue involvement, and reports no new clinical results.

This article provides an overview of lipedematous scalp, a rare condition characterized by a thickened scalp without hair loss, and emphasizes the need for further research due to limited case reports.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

This report presents a rare case of lichen spinulosus in a 52-year-old woman, featuring hyperkeratotic follicular papules and a dense lymphohistiocytic infiltrate in affected skin areas.

This review discusses the etiology, clinical features, and treatment options for lipedema and lipedematous scalp and reports no new clinical results.

This case report documents the rare occurrence of lipedematous scalp in two black Caribbean female siblings, suggesting a potential genetic factor and noting psychiatric co-morbidities as novel associations.

This study investigated the relationship between lichen planus and dyslipidemia but did not report any clinical findings.

This case report describes a 52-year-old black woman with diffuse scalp swelling and thinning hair attributed to a large increase in the thickness of scalp subcutaneous fatty tissue.

This study details the characteristics of lipedematous alopecia and lipedematous scalp, two rare scalp conditions, suggesting they may represent different stages of the same disorder, with lipedematous scalp lacking the hair loss seen in lipedematous alopecia.

This study suggests that lipin-1 plays a crucial role in keratinocyte differentiation by modulating protein kinase C activity through diacylglycerol levels, with implications for skin biology.

This study used cryoelectron microscopy to unveil the structure of LPA-bound human LPAR6, revealing unique ligand binding and recognition modes distinct from LPAR1, which may aid in designing targeted compounds for hair loss and cancer.

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.

This review discusses the pathophysiologic role of lysophosphatidic acid in the skin and reports no clinical results, suggesting pharmacological inhibition as a potential treatment for various skin disorders.

This case report describes instances of lipedematous scalp and lipedematous alopecia in white adults, indicating these rare conditions may be more widespread and frequent in this population than previously thought.
