November 2025 in “Journal of Microbiology and Biotechnology” In this study, combining Botulinum toxin type A with Platelet-rich plasma was found to enhance hair follicle growth and reconstruction, potentially through inflammation reduction and activation of the Wnt/β-catenin pathway via STMN1 protein modulation.
November 2025 in “Journal of Investigative Dermatology” Combining MMP-9 and JAK inhibitors can effectively prevent skin depigmentation in vitiligo.
November 2025 in “Journal of Investigative Dermatology” Dithranol reduces inflammation in alopecia areata by lowering certain immune responses.
November 2025 in “JEADV Clinical Practice” In this retrospective cohort study, patients using leflunomide for primary autoimmune conditions showed a decreased risk of developing alopecia areata, while those using methotrexate, cyclosporine, and rituximab had an increased risk.
This study found that platelet-rich plasma might support brain health by enhancing glial cell function and modulating immune responses in inflammation, indicating potential as a treatment for brain disorders.
October 2025 in “Dermatology Practical & Conceptual” This review discusses different types of alopecia associated with psoriasis and highlights that hair loss in psoriasis is typically non-scarring and reversible, while also noting the increased risk of alopecia areata in these patients.
September 2025 in “Diseases” This study found that patients with patchy alopecia areata had significantly higher serum levels of pro-inflammatory cytokines IL-6, TNF-α, IL-17A, and IL-21 compared to healthy controls, with these levels correlating positively with disease severity, age, and disease duration.
August 2025 in “International Journal of Molecular Sciences” This study found that compounds isolated from Osmanthus fragrans var. aurantiacus demonstrated antioxidative and anti-inflammatory activities, potentially offering therapeutic benefits for inflammatory bowel diseases by inhibiting COX-2 and iNOS enzymes and blocking ERK 1/2 MAPK signaling.
August 2025 in “Frontiers in Pharmacology” In this study, PA-011, a traditional Chinese medicine extract, was shown to improve hair growth in alopecia areata model mice by reducing skin inflammation and altering skin microbiota, indicating its potential therapeutic role for this condition.
August 2025 in “Acta Biomaterialia” This study presents a novel hydrogel scaffold made from tilapia collagen, which when activated by ultrasound, reprograms macrophages to promote wound healing, enhance angiogenesis, and stimulate hair follicle regeneration, offering a potential new method for treating inflammatory wounds.
August 2025 in “OPAL (Open@LaTrobe) (La Trobe University)” In this study, PA-011 extract was reported to promote hair growth and alleviate alopecia areata symptoms in mice by reducing skin inflammation and modulating skin microbiota.
In this study assessing post-menopausal Asian women, distinct shifts in Malassezia species prevalence on the skin were linked to increased inflammation and impaired skin barrier function, potentially driving disorders like psoriasis and seborrheic dermatitis.
