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

In this case report, a 38-year-old woman with Parry–Romberg syndrome displayed left-sided facial atrophy and subclinical central nervous system involvement detectable by neuroimaging, suggesting that even symptom-free cases may benefit from systematic brain evaluations.

This study identified specific genetic variants as the cause of visual impairment and non-syndromic alopecia in two brothers, reinforcing the link between PDE6H variants and achromatopsia and LPAR6 variants and alopecia.

This study reports that in MRL mice, loss of p53 does not impair ear regeneration, suggesting p21's potential role in this process may involve the Tgfb/Smad pathway.

This study found that RXRα/RARγ heterodimers are necessary for retinoic acid-induced keratinocyte proliferation in the skin, while normal epidermal maintenance does not require RAR-mediated signaling.

This study found that platelet-rich plasma injections for vocal fold scarring and atrophy showed a favorable safety profile and subjective improvements in vocal quality and fatigue over a three-month follow-up.

This report details the development of a PSR™ Terminalia extract with antioxidant and anti-aging potential, highlighting its rich composition in phenolic acids, polysaccharides, and organic acids, without new clinical results.

This study suggests that platelet-rich plasma may provide short-term improvement in hair density for female pattern hair loss, but results varied and more rigorous trials are needed to establish optimal protocols.

CD8+ T cells re-expressing CD45RA may predict treatment resistance in severe alopecia areata.

This narrative review reported that intradermal injection of autologous platelet-rich plasma showed objective improvement and increased patient satisfaction in treating periorbital wrinkles, though the authors noted the need for further rigorous studies to confirm these findings.

This article discusses the use of Platelet Rich Plasma therapy for skin rejuvenation and hair loss and reports no new clinical results, noting its minimally invasive nature and effect on skin texture and elasticity.

This study found that low-level laser therapy may reduce inflammation and increase hair thickness in patients with lichen planopilaris after six months of treatment, though the small sample size limits the findings.

This article reviews multiple noncutaneous manifestations of pityriasis rubra pilaris, such as subungual hyperkeratosis and hair loss, but reports no new clinical results.

This study found that ALRN-6924, a clinical-stage dual inhibitor, can selectively protect human scalp hair follicles from paclitaxel-induced toxicity and damage by inducing transient cell cycle arrest in healthy cells without affecting cancer cells, potentially reducing chemotherapy-induced alopecia.

This study found that postmenopausal women with lichen planopilaris showed a high prevalence of androgen excess, while women with frontal fibrosing alopecia were often associated with androgen deficiency.

This study identified that Eda-A1 unexpectedly induces placode inhibitors dkk4 and lrp4, indicating the importance of tightly regulated signaling for proper ectodermal organ development.

This study observed that POMP is strongly expressed in the root sheath hair follicles of Liaoning Cashmere goats and its expression can be regulated by certain factors, which may influence cashmere growth.

This study suggests that alkaline phosphatase-regulated expression of CCL5 contributes to the trichogenicity of human dermal papilla spheres.

This article discusses the therapeutic use of platelet-rich plasma (PRP) in dermatology, specifically its challenges and potential in treating conditions like lichen planopilaris, but reports no new findings.

This study found that epidermal growth factor receptor and mitogen activated protein kinase inhibitors down-regulate PD-L1 expression in human hair follicles, which may contribute to sterile folliculitis in treated patients.

This study found that Platelet-Rich Plasma (PRP) stimulated human hair growth more effectively than other tested culture media in vitro.

Choose IPL for versatility and speed, ruby lasers for precision.

This review examines the definition, classification, mechanism, clinical efficacy for hair regrowth, and potential adverse effects of platelet rich plasma, but does not present new experimental results.

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.

This study investigated AHR signaling's role in skin biology and reported that novel AHR ligands may help restore keratinocyte function and reduce inflammation in skin diseases, suggesting their potential as therapeutic agents.

This study found that platelet-rich plasma may be an effective adjuvant treatment for androgenetic alopecia, especially when combined with antiandrogenetic medications and topical minoxidil, though factors like patient age and family history could influence outcomes.

This review discusses various aesthetic and regenerative applications of platelet-rich plasma and concludes that it has potential as a safe cosmetic intervention but requires further studies to understand its clinical effects.

This study found that programmed death-ligand 1 (PD-L1) levels correlated with the severity of alopecia areata, suggesting its potential as an indicator and possible target for new treatments.

This article reviews the regenerative benefits of platelet-rich plasma in various medical fields, particularly in dermatology and aesthetic medicine, without presenting new clinical data.
