This study found that IL-17 expression was significantly higher in perifollicular fibrosis of active Lichen planopilaris lesions, suggesting that targeting IL-17 could impact the disease's progression.

This study compares the prevalence of vitamin D deficiency in patients with lichen planopilaris/frontal fibrosing alopecia to the general US population, highlighting an area not well-explored in existing research.

This review discusses treatments for frontal fibrosing alopecia and lichen planopilaris, noting that systemic 5-alpha reductase inhibitors are most effective for stabilization and potential hair regrowth, but reports no new clinical results.

This study identified discoid lupus erythematosus and pseudopelade of Brocq as the leading causes of scarring alopecia, highlighting the importance of skin punch biopsy for accurate diagnosis.

This review discusses the classification of lichen planopilaris and its subtypes under the proposed term "lichenoid alopecias," suggesting they exist along a clinical and histological spectrum.

This review discusses the characteristics and diagnostic challenges of fibrosing alopecia pattern distribution, proposing an algorithm for hair transplantation, but reports no new clinical results.

This article discusses the causes and treatment options for lichen planopilaris, a scarring hair loss condition, but reports no new clinical findings.

This review discusses the various applications of lyophilized platelet-rich plasma in treating different diseases and reports no new clinical results.

This article reviews the characteristics and presentation of fibrosing alopecia in a pattern distribution, a form of scarring alopecia similar to androgenetic alopecia and lichen planopilaris, but provides no new clinical findings.

This study found that an ethanolic extract from the microalga Tetrathelmis tetrathele exhibited anti-inflammatory effects, promoted the proliferation of certain skin and hair cells, and inhibited 5α-reductase activity, suggesting its potential as a therapeutic agent for preventing alopecia and enhancing scalp health.

This manuscript describes a proposed ‘trichoscopy-assisted hair pull test’ that enhances the diagnosis of hair loss conditions by allowing immediate examination of proximal hair shafts and roots in patients with a positive hair pull test.

This article discusses Graham-Little Piccardi Lassueur Syndrome, a rare variant of Lichen planopilaris, but reports no clinical findings or results.

This study found that CD1a-restricted CD4+ T cells responsive to lysyl-phosphatidylglycerol were more frequent in the blood of atopic dermatitis patients, suggesting a potential role in the disease's Th2-mediated pathology.

This study examined clinical characteristics of lichen planopilaris and frontal fibrosing alopecia in 24 men, revealing common scalp symptoms, frequent beard involvement, and limited association with thyroid disease.

This article reviews the complexities and challenges in hair transplant procedures, emphasizing the role of micro-inflammation and the usefulness of trichoscopy for detecting complications, and reports no new clinical results.

This chapter reviews trichoscopic features of primary cicatricial alopecias, particularly lichen planopilaris and frontal fibrosing alopecia, and reports no new results.

This study found that trichoscopy, a non-invasive diagnostic method, may effectively differentiate between types of focal alopecia in the parietal area in adult women, indicating specific trichoscopic features for conditions like alopecia areata, discoid lupus erythematosus, and lichen planopilaris.

This discussion highlights the evolving clinical spectrum of lichen planopilaris, noting atypical features and presentations in younger males that suggest potential different pathomechanisms from previously recognized variants.

In this case study, a 69-year-old woman with pityriasis rubra pilaris developed a scarring alopecia with lichen-planopilaris-like features, which responded well to early treatment.

This study found that fibrosis-associated trochanters in central centrifugal cicatricial alopecia are enriched with hair follicle stem cells and may indicate a disrupted stem cell niche contributing to scarring.

This study found that disrupting testosterone biosynthesis in male rats mitigated cardiovascular and autonomic impairments caused by endotoxemia, indicating testosterone's significant role in these conditions.

This article reviews current understanding of frontal fibrosing alopecia and lichen planopilaris, highlighting increasing incidence and unclear pathogenesis, and emphasizes the role of inflammatory destruction of hair follicular stem cells; it reports no new clinical findings.

Isotretinoin at low doses effectively treats facial papules in frontal fibrosing alopecia.

This study found that lichen planopilaris is associated with three core molecular pathways, which may inform new therapeutic strategies for scarring alopecia, including unique pathways like ABC transporters specific to LPP.

In this study, researchers evaluated trichoscopic features in 500 Egyptian patients with patchy hair loss and found specific patterns, such as perifollicular scale with 90% sensitivity and 99.5% specificity, which effectively aid in diagnosing primary cicatricial alopecias.

This study found that DK peptides demonstrated potent inhibition of 5α-reductase, suggesting they may be promising candidates for treating hair loss.

This study observed that inflammatory stimuli significantly altered gene expression in rat theca-interstitial cells, affecting pathways related to growth and androgen production, which are central features of polycystic ovary syndrome.

This study highlights lichen planopilaris as a form of scarring hair loss with symptoms like shedding and itching, and notes successful treatment options such as topical and oral antiinflammatory medications to preserve hair follicles by early intervention.

This study found that the PPAR-γ modulator AGED can reverse epithelial-mesenchymal transition in hair follicles affected by lichen planopilaris ex vivo, suggesting potential for treating scarring alopecias.

This study suggests that macrophages play a more substantial role in the pathogenesis of Lichen planopilaris compared to Frontal fibrosing alopecia, as indicated by increased CD68+ cells in Lichen planopilaris.
