This case study highlights that even professional eyebrow tinting can lead to chemical burns, and increasing consumer awareness is crucial as its popularity grows and unregulated products become more common.

This article highlights the health risks associated with adding paraphenylenediamine to mehndi, such as contact dermatitis and asthma, and emphasizes the need for regulatory checks as its use grows among cancer patients, women with alopecia, and pregnant individuals.

This study observed that sebaceous glands were preserved in some patients with central centrifugal cicatricial alopecia, suggesting early gland loss may not be a key feature of the condition.

This review highlights a case of cross sensitization to dyes from temporary henna tattoos and stresses the need for public awareness on the risks associated with these tattoos.

This review discusses the potential antiandrogenic effects of environmental chemicals on reproductive development, highlighting concerns about their impacts on humans but reports no new clinical findings.

This study demonstrated that steroidal carbamates 7–10 altered mRNA expression related to lipid metabolism in hamster flank organs and inhibited 5α-reductase activity without binding to the progesterone receptor.

This study observed that inducible deletion of the Ugcg gene in mouse epidermis led to a significant reduction in GlcCers and epidermal POS-Cers, causing impaired skin barrier function and delayed wound healing.

This study found that 20% of children initially diagnosed with premature pubarche were later identified with other conditions like central puberty precox or congenital adrenal hyperplasia during follow-up, emphasizing the importance of ongoing differential diagnosis.

This study found that 20% of children initially diagnosed with premature pubarche were later identified with different clinical conditions during follow-up, highlighting the need for careful differential diagnosis over time.

This study observed that sebaceous gland atrophy in psoriatic lesions correlates with the down-regulation of specific lipid biosynthetic gene modules, potentially affecting hair appearance without damaging follicles.

In this study, PP-PTKL exhibited antioxidant, anti-inflammatory, and pro-melanogenic effects in laboratory settings, suggesting its potential role in preventing or treating hair greying. Further animal and human studies are needed to verify these findings.

In this case series conducted in Austrian dermatology clinics, tralokinumab was found to be a well-tolerated and effective long-term treatment for adults with moderate-to-severe atopic dermatitis, with improvements in eczema severity and symptom suppression maintained over up to three years.

This study developed a natural herbal hair dye powder using Eclipta prostrata, Nigella sativa, and Aloe Vera, which offers safe and environmentally friendly hair coloring while avoiding harmful effects associated with conventional dyes.

In this review, various expression systems for synthesizing recombinant collagen are compared, highlighting their efficiency, modification capabilities, and cost. Key purification techniques are also analyzed, and challenges like reducing R&D costs and improving safety protocols are identified.

This review explains that dysregulated sebum secretion and composition contribute to acne and impaired skin barriers while highlighting factors like diet and hormones affecting sebaceous activity, and identifies novel molecular targets and model systems for future therapeutic developments.

This study reported that horses with pituitary pars intermedia dysfunction had improved coat condition, advanced shedding, and better quality of life when treated with blue light masks.

This study investigated the potential mechanisms of Curcuma aeruginosa in treating androgenetic alopecia and identified 66 bioactive compounds interacting with proteins involved in the disorder, suggesting its involvement in hormone response and specific signaling pathways.

This review discusses the potential of P. polyphylla saponins to treat acne through antibacterial, anti-inflammatory, immunomodulatory, and antioxidant effects, noting that acne's complex pathogenesis makes this line of research promising for future studies.

This study found that in primary cicatricial alopecia, reducing cholesterol production and targeting EMT modulators like PPARγ, AhR, AGTR, and TGFβ with siRNA may help mitigate hair follicle damage by modulating epithelial-mesenchymal transition, suggesting potential therapeutic strategies for slowing PCA progression.

In this randomized controlled trial, the nutritional supplement PPT5 α was associated with increased terminal hair percentages and improved self-assessed hair parameters in women with early-stage androgenetic alopecia.

This case report described a facial hairline tumor initially diagnosed as a sebaceous cyst but ultimately confirmed as a rare Proliferating Pilar Tumor with focal malignancies upon histopathological examination.

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 plasma protein binding significantly contributes to the shifts in glucocorticosteroid concentration ratios among blood, saliva, and hair, challenging prior assumptions about enzyme inactivation as the main factor.

This observational study reports a striking correlation between the use of henna hair dye and a specific pattern of hair loss, termed "hennapecia," but calls for experimental research to determine causality.

This study found that hair regrowth differed by position on mouse dorsal skin, appearing earlier at cranial sites compared to caudal sites, and revealed distinct gene expression profiles between these regions, impacting the design and interpretation of hair-regeneration experiments.

This review discusses the dermatological and systemic adverse effects of hair dye use, particularly focusing on the common allergen para-phenylenediamine, and reports no new clinical data.

This infographic compares the safety profiles of SH‑1, a cosmetic ingredient, which showed no systemic absorption, and PP405, an investigational drug with dose-dependent systemic uptake and potential threshold breaches, highlighting differences in safety between cosmetic and investigational substances according to this report.

This study found that periodic red light exposure in aged mice increased histone acetylation and activated metabolic processes in keratinocytes, mitigating cellular aging through enhanced fatty acid oxidation and altered gene expression related to lipid metabolism.

This study found that periodic red light exposure increased histone acetylation and activated metabolic processes in aged mice, leading to enhanced fatty acid oxidation and the mitigation of cellular aging by influencing gene expression and metabolic regulation.

In this study, periodic exposure to red light in aged mice led to increased histone acetylation and activated mitochondrial fatty acid oxidation, which collectively mitigated cellular aging by modulating metabolism, inflammation, and gene expression.
