This review discusses lichen planopilaris in children and highlights its rarity, potential for misdiagnosis, and need for suspicion in atypical or treatment-resistant alopecia cases, but reports no new results.

This study cataloged several long non-coding RNAs and microRNAs in cashmere goat dermal papilla cells, suggesting these non-coding RNAs may play a role in hair follicle stem cell activation and hair growth.

This study suggests that Mrp3 may play a role in both wound healing and the hair follicle cycle as a growth factor and/or angiogenesis factor.

This case report highlights a misdiagnosis of traction alopecia that progressed to lichen planopilaris in a patient of color, emphasizing the need to consider LPP in similar cases due to differing treatments.

This study reported that the PrrH sRNA in *Pseudomonas aeruginosa* may directly regulate genes involved in pyochelin siderophore biosynthesis, highlighting its role in adapting to heme availability, with light conditions influencing this gene expression.

This study identified a new PNPLA1 mutation in a Spanish family with autosomal recessive congenital ichthyosis.

In this study, key histologic features such as mucinous perifollicular fibroplasia were identified to aid in the diagnosis of lichen planopilaris.

Defective protein folding due to a mutation is key in ANE syndrome.

This study found that lysophosphatidic acid increases mesenchymal stem cell proliferation and migration through signaling pathways and reactive oxygen species, implicating potential applications in stem cell expansion.

This overview discusses primary cicatricial alopecias, focusing on lichen planopilaris, and highlights the challenges in treatment and the progressive nature of hair loss despite symptom management, without providing new clinical results.

This study found diverse clinical presentations of lichen planopilaris, with classic lichen planopilaris being the most common, highlighting the importance of recognizing this variability for accurate diagnosis.

This study suggests that Ptprq in the hair bundles may exist as multiple isoforms that are differentially expressed throughout development and affect the organization of stereocilia in the chick inner ear.

This study found that in Lichen Planopilaris, the Microbacteriaceae family was negatively correlated with IL-23 expression, suggesting a role in the disease's inflammation and microbiota composition.

This study demonstrated that LGR5 is a marker of hair follicle stem cells across species using a transgenic pig model and noted similarities and differences in expression patterns compared to humans.

This study isolated and sequenced the complete gene rKAP4L1, which encodes a cysteine-rich hair keratin-associated protein in rabbit hair follicles.

This study found that melatonin-mediated lncRNA018392 accelerated cell proliferation and inhibited apoptosis in cashmere goat skin fibroblasts by upregulating the expression of the nearby gene CSF1R.

This case report found that a novel botanical treatment halted disease progression and promoted hair regrowth in four patients with lichen planopilaris, indicating potential for use as a safe alternative therapy.

This paper presents a case of a young male with linear and annular lupus panniculitis of the scalp, detailing trichoscopic findings and their correlation with histopathological features, but reports no new generalizable results.

This study found that lncRNA-599554 contributes to the inductive ability of dermal papilla cells in cashmere goats by sponging miR-15a-5p, promoting Wnt3a expression, and potentially influencing hair follicle regeneration.

This case report details two patients with Graham-Little-Piccardi-Lassueur syndrome who showed marked skin lesion improvement with corticosteroid treatment, though cicatricial scalp alopecia remained unresponsive.

This study found that RSPO1 mutations in patients with a 46XX disorder of sexual development contribute to impaired skin integrity and increased risk of squamous cell carcinoma in areas subject to friction.

This review discusses lipid-polymer hybrid nanoparticles for dermatological applications, outlining their structural and formulation advancements, but reports no new clinical results and calls for further research on their therapeutic potential.

This case study documented the first known instance of biopsy-confirmed lichen planopilaris occurring after hairline-lowering surgery in a patient without prior history, highlighting a potential complication where surgical trauma may trigger immune-mediated hair loss.

This study found that cPPARγ and dnPPARγ isoforms are differentially expressed in healthy human skin, suggesting that PPARγ modulators may have compartment-specific effects depending on isoform presence.

In this study, a 3-year-old Japanese child with autosomal recessive woolly hair was found to have a distinctive irregular and rough cuticle on the hair shaft, along with a homozygous pathogenic LIPH variant, suggesting a critical role for genetic analysis in understanding rare hair conditions.

This study suggests that Lrig1-positive cells form a previously unknown reservoir of interfollicular epidermal stem cells in adult mouse skin, influencing epidermal proliferation and hair follicle development.

This study identified differentially expressed mRNAs and lncRNAs in Hu sheep hair follicles, suggesting certain genes and pathways are involved in the development of wool curvature patterns.

This study introduced rPanglaoDB, an R package that facilitates the integration of public scRNA-seq datasets to effectively characterize rare cell types, exemplified by generating the first unbiased transcriptome profile of fibrocytes.
