This study found that C57BL/6 mice with a diet containing specific levels of vitamin A showed alterations in retinoid metabolism and increased frequency of cicatricial alopecias, suggesting dietary factors may play a role in this condition.

This article is a letter discussing optical coherence tomography-assisted diagnosis of follicular keratosis of the chin and reports no new research findings.

The document concludes that various skin conditions have specific treatments, ranging from antihistamines for urticaria to surgery and medication for tumors and chronic skin diseases.

This review discusses genetic mutations associated with Hutchinson-Gilford progeria syndrome and reports no clinical results; the authors emphasize the importance of cardiovascular monitoring in management.

This study found that IBS is positively associated with psoriasis, rosacea, and urticaria, but inversely associated with acne and vitiligo.

In this laboratory study, Cucumis melo var. makuwa leaf extract significantly reduced DHT-induced apoptosis in human dermal papilla cells by modulating androgen receptor activity and gene expression, suggesting potential as a therapy for androgenetic alopecia.

This study investigated the role of the ABCA4 gene in human keratinocytes and hair follicle stem cells and found that silencing the ABCA4 gene increases the harmful effects of all-trans-retinal on hair follicle stem cells.

Most children with alopecia areata improved with treatment, but those with more hair loss had worse outcomes.

This study found that proretinal nanoparticles, applied topically, are safe and effective for penetration into hair follicles, enhancing retinoid biological activity in the skin while reducing irritation compared to conventional retinal formulations.

Eating more omega-3 and less omega-6 fatty acids may lower the risk of developing prostate cancer.

A man's red tattoo caused a skin reaction and hair loss in his beard, which improved after treatment.

This case-control study found that men with earlier onset androgenetic alopecia, particularly frontal balding, may have an increased risk of prostate cancer in a multiethnic veterans cohort.

This study identified a distinct cytokine activation signature in alopecia areata, involving TH2, TH1, IL-23, and IL-9/TH9 pathways, suggesting potential targeting strategies similar to those in psoriasis and atopic dermatitis.

This review explores animal models of alopecia areata, particularly focusing on the insights they've provided into the disease's immune mechanisms and potential treatment approaches, without reporting new experimental data.

This article reviews the causal mechanisms of hair follicle disorders, focusing on inflammation, genetics, environment, and hormones, but it reports no new clinical results.

This review discusses recent advances in understanding the pathogenesis of autoimmune alopecia areata and reports no new clinical results; it highlights potential for developing more effective treatments.

This study found that late-onset alopecia areata is more common in women and tends to present with milder symptoms, with some patients achieving complete hair regrowth in mild cases.

This study found that alopecia areata patients had increased insulin resistance compared to controls, suggesting a potential link between inflammation, stress axis activation, and insulin resistance in this population.

This study observed that carboxytherapy significantly improved clinical and dermoscopic measures in patients with alopecia areata and androgenetic alopecia compared to placebo, though some benefits regressed during follow-up.

In this study, fractional CO2 laser treatment for alopecia areata was found to significantly increase terminal hair and patient satisfaction compared to betamethasone valerate cream alone, highlighting its efficacy and safety both as a standalone and combined treatment.

This study presents two cases where intralesional methotrexate combined with ablative fractional CO2 laser treatment resulted in excellent outcomes for refractory alopecia areata.

This study observed a significant increase in cellular retinol-binding protein-1 expression in lesional skin of patients with alopecia areata compared to healthy controls, suggesting its potential role in the disease's pathogenesis.

This study observed a significant association between antigliadin antibodies (IgA and IgG) and alopecia areata severity, suggesting that serological tests could help diagnose subclinical celiac disease in these patients, with IgA and IgG showing 100% sensitivity and specificity at specific cutoff points.

This study highlights the genetic complexities in alopecia areata, emphasizing the role of microRNAs and their association with other immune-related diseases, which could inform targeted treatment strategies.

This review reports that Janus kinase inhibitors and regenerative therapies, such as exosomes and platelet-rich plasma, significantly improve scalp hair regrowth in moderate-to-severe alopecia areata, though challenges like high relapse rates and socioeconomic barriers remain, underscoring the need for personalized treatment protocols.

This study found that lower vitamin D levels were inversely associated with the severity of female pattern hair loss and patchy alopecia areata, but not with telogen effluvium.

This review discusses the role of immune cells in the pathogenesis of alopecia areata and highlights emerging immunomodulatory strategies and novel therapeutic targets aimed at offering more effective and durable treatments for this autoimmune hair loss disorder.

In this clinical study, researchers reported that both sodium valproate-loaded nanospanlastics and topical corticosteroids showed comparable modest efficacy in treating patchy alopecia areata, recommending further investigation into sodium valproate's role combined with other therapies.

This study reports two cases of severe alopecia areata showing seemingly permanent hair regrowth with a modified triamcinolone acetonide regimen involving epinephrine, and suggests a potential role for epinephrine in enhancing treatment efficacy.

This study found a significant association between antigliadin antibodies (IgA and IgG) and alopecia areata severity, suggesting a need for celiac disease screening in these patients.
