In this pilot study, PDLLA scalp microinjections showed improvement in physician-rated Global Aesthetic Improvement Scale scores over 12-24 weeks for 90% of patients with non-scarring alopecia, with no serious adverse events reported, although findings remain preliminary due to methodological limitations.

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.

The study suggests that immune privilege collapse in bulge cells and the involvement of pro-inflammatory cytokine interferon-γ contribute to hair follicle stem cell loss in lichen planopilaris.

This study reported that lichen planopilaris predominantly affects females over 60, with a registered prevalence rate of 0.02581%, and is often associated with autoimmune diseases like systemic lupus erythematosus, suggesting a need for further research to enhance treatment approaches.

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 study provides one of the first descriptions of the demographic, clinical, and therapeutic characteristics of lichen planopilaris in Chilean adults, reporting that treatment usually reduced or halted disease progression.

This report describes two cases where lichen planopilaris may have compromised the hair follicles in both donor and recipient areas following follicular unit transplantation.

This article in the International Journal of Dermatology reports on a case series where the drug upadacitinib was used to treat patients with recalcitrant lichen planopilaris, but no abstract or detailed results are provided to assess its efficacy or safety fully.

This study found that treatment improved symptoms and stopped disease progression for 75% of lichen planopilaris patients whose follow-up data were available.

This study found that line-field confocal optical coherence tomography effectively visualized key diagnostic features of classic lichen planopilaris in real time, suggesting its potential as a valuable diagnostic tool.

In this research, RNA expression analysis of scalp biopsies from lichen planopilaris patients revealed changes in specific genes after treatments with hydroxychloroquine, narrow band UVB, or low level laser light therapy, suggesting potential biomarkers and implicating M2 macrophages in the disease's immunopathogenesis.

This reported case of lichen planopilaris in siblings suggests a potential genetic predisposition, supporting the hypothesis of inherited susceptibility in this condition.

This study found that immune privilege collapse in the hair follicle bulge and associated immune responses may contribute significantly to the pathogenesis of lichen planopilaris, suggesting a potential autoimmune basis for the disease.

PRP treatment improved skin pigmentation and appearance in facial lichen planus pigmentosus.

This case study reports that a 35-year-old woman developed nonscarring alopecia following the cosmetic use of poly-L-lactic acid on her face and hairline.

This extensive review discusses the clinical manifestations, potential associations, and treatment approaches for lichen planus, but reports no new clinical results, highlighting gaps in evidence for therapeutic strategies.

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 discusses clinical cases of Lichen Planopilaris in men that were initially misdiagnosed and inadequately treated, resulting in significant irreversible hair loss.

This study identified a new subtype of lichen planopilaris that mimics androgenetic alopecia, selectively affecting vellus hair follicles and presenting unique histopathological features.

This paper reviews treatments for lichen planopilaris, including low-level laser therapy, but reports no new clinical results and highlights the need for further research.

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

This study suggests a potential role for S100A7 and IL-17 in the pathogenesis of lichen planopilaris.

This abstract discusses the prevalence and forms of lichen planopilaris, a type of scarring hair loss, but reports no new clinical findings.

The researchers reported that the facial Psoriasis Log-based Area and Severity Index (fPLASI) more reliably and sensitively captured clinical improvement in facial psoriasis than the existing facial Psoriasis Area and Severity Index (fPASI).

Lichen planus pigmentosus and fibrosing frontal alopecia in Colombia are likely different stages of the same disease.

This article discusses the importance of early recognition of LPP due to its significant aesthetic and psychosocial effects and calls for efforts to prevent misdiagnosis.

Women in Australia report different signs of facial aging compared to women in the US, UK, and Canada; men with Lichen planopilaris often have hormonal abnormalities and thyroid disease.

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 study found that female patients with frontal fibrosing alopecia are significantly more likely to have systemic lupus erythematosus compared to controls.
