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 study found that low-intensity light therapy improved quality of life related to emotional, psychosocial, and symptom domains in individuals with androgenic alopecia, with a greater impact observed in women.

This article introduces a series on low level laser light therapy, focusing on its science, regulatory aspects, and controlled trial methodologies, but reports no new clinical results.

The abstract highlights that lichen planus can manifest as cicatricial alopecia or lichen planopilaris, while discoid lupus erythematosus, a common form of lupus erythematosus, typically causes scarring alopecia. Results are not reported here.

This review discusses low-level laser or light devices as an alternative treatment for androgenetic alopecia and highlights the need for further research to compare their efficacy with existing therapies.

This review discusses the effects of low-level laser therapy in various biological processes for wound healing and tissue repair and reports no new results.

This paper presents diagnostic characteristics obtained from various analytical methods to support the pharmacognostic standardization of Lawsonia inermis L. leaf, commonly known as henna.

This study identified distinctive trichoscopic features that may aid in diagnosing loose anagen hair syndrome, such as rectangular black granular structures, solitary yellow dots, and a predominance of follicular units with single hairs.

This case report observed that resection of a lesion using a carbon-dioxide laser in a Labrador retriever with lingual hair heterotopia led to positive outcomes, although hair partially regrew.

This study reviewed clinical trials and found that low-level laser therapy significantly increased hair diameter or density in both men and women with pattern hair loss compared to a sham device, though the involvement of industry relationships in some studies suggests cautious interpretation.

In this study, the CYP 21A2 gene p.V281L mutation was associated with an increased susceptibility to familial frontal fibrosing alopecia, suggesting an antigen-driven mechanism linked to certain human leukocyte antigen haplotypes.

This study found that elevated luteinizing hormone levels were significantly associated with female pattern hair loss, and implicated LH/LHR signaling in the aging and damage of hair follicles.

In this case report, a rare instance of Graham–Little–Piccardi–Lassueur syndrome coexisting with linear lichen planus was identified in a 35-year-old male, highlighting the condition's rarity in males, with dermoscopy aiding diagnosis through distinctive scalp and trunk lesion features.

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 case report highlights a rare presentation of acute lupus hemophagocytic syndrome with initially negative antinuclear antibodies, underscoring the higher sensitivity of the 2012 Systemic Lupus International Collaborating Clinics criteria for diagnosis.

In a 24-week randomized trial, this study found that the RAMACAP laser helmet significantly increased hair density and diameter in androgenetic alopecia patients compared to a sham device, although limitations included a small sample size and potential issues with the control used.

In this study, PDLLA treatment in middle-aged mice was observed to enhance hair growth by increasing macrophage M2 polarization and hair follicle stem cell proliferation, potentially rejuvenating the skin's microenvironment and offering a novel approach for age-related hair loss.

In this case study, a 70-year-old male with lymphoid variant hypereosinophilic syndrome presented with rare isolated pulmonary involvement, which improved with prednisone treatment.

This article discusses the potential of combining growth factor therapy with LLLT LED therapy for hair regrowth in androgenetic alopecia, but it does not report new clinical results.

This study evaluated the safety and effectiveness of HASHA, a new hyaluronic acid injectable, for chin augmentation in adults with chin retrusion. HASHA significantly improved chin appearance and satisfaction over 12 months compared to controls, with only mild or moderate transient adverse events.

This article describes a rare case of syringolymphoid hyperplasia with alopecia and anhidrosis in a female patient, emphasizing challenges in diagnosis and treatment unresponsiveness despite the condition's link to mycosis fungoides.

A specific gene mutation causes sparse, brittle hair in a family.

This article discusses the use of low-level laser therapy for hair regrowth in men and women but reports no new clinical results; it reviews types of lasers and evidence from animal and human studies.

This study reveals that hair follicles in mice and humans recruit epidermal Langerhans cells during skin inflammation via specific chemokine signaling pathways.

This study found that using a low-level light therapy helmet device daily for 24 weeks improved hair density and thickness among participants, though it did not significantly impact sebum secretion or erythema index.

Low-level light therapy significantly increased hair density and thickness in people with hair loss, but they didn't notice a difference.

This article reviews the basics of hair follicle biology, laser/tissue interactions, and hirsutism and hypertrichosis causes, discussing the long-pulsed alexandrite laser's role in hair reduction without reporting new clinical results.

LLLT is a safe, promising hair loss treatment, but more research needed.

This review discusses the potential mechanisms and evidence supporting low-level laser therapy for stimulating hair growth in men and women, while noting its safety and effectiveness but needing further study on specific parameters.
