This study found that the petroleum ether extract of Solanum nigrum may promote hair regrowth in testosterone-induced hair loss in rats, as indicated by increased follicle density and anagen/telogen ratio.

In this study, researchers developed a new sodium alginate/chitosan/Zn2+ hydrogel that showed improved physical properties, antibacterial activity, and biocompatibility, and demonstrated enhanced wound healing and skin regeneration in an in vitro model.

In this study, the novel isoprenylcysteine analog SIG-1451 was shown to inhibit pro-inflammatory cytokine release in various cell-based assays relevant to allergic dermatitis, acting on targets such as IL-4 and IL-6 with potential anti-inflammatory benefits.

This study demonstrated that stress-derived neurosteroid THDOC shifts from inhibiting to activating the HPA axis under stress, presenting potential therapeutic targets for stress-related disorders.

This study found that synchronized signals in the microenvironment regulate stem cell lineage choices in hair follicles by influencing chromatin dynamics during regeneration.

This study found that the Stem Cell Educator therapy improved hair regrowth and quality of life in patients with severe alopecia areata by restoring immune balance and protecting hair follicles from autoimmune damage.

The researchers reported that in mice, prolactin signaling in the skin epithelium inhibits hair follicle stem cell activation, promoting quiescence during periods of high serum prolactin like pregnancy and lactation.

This study found that both finasteride and dutasteride significantly reduced L-DOPA-induced dyskinesia in a rat model of Parkinson's disease, with dutasteride showing greater effectiveness at lower doses.

This study presents a method for directly measuring the solubility of solid chemicals in the skin's stratum corneum under various humidity conditions, emphasizing its importance for dermal drug delivery and chemical safety assessments.

In a randomized, double-blinded, placebo-controlled clinical trial, this study found that the botanical-based compound ALRV5XR significantly increased hair regrowth in women with androgenetic alopecia or telogen effluvium, with no adverse events reported.

Several companies launched new hair care ingredients in 2011 to improve conditioning, color retention, combability, and heat protection.

Hormonal contraceptives are effective for teens but require careful consideration of side effects and individual health.

This study found that spironolactone reduced serum androstenedione and anagen hair shaft diameter in hirsute patients but did not significantly alter unbound testosterone levels, suggesting its effects are primarily peripheral.

This review examines various skin pigmentation disorders, their causes, and potential treatments, detailing 25 plants, 4 marine species, and 17 clinically tested topical and oral medications for managing these conditions.

In this study, transgender adolescents treated with testosterone for a median of 12 months experienced effective virilization, including voice deepening and increased hair growth, but also showed decreased HDL cholesterol and BMD z-scores, and increased hematocrit, with no short-term safety issues reported.

A missing mK6irs1 gene causes hair loss in mice.

This review discusses the types, causes, and treatments for skin pigmentation disorders, examining clinically tested options including 25 plants, four marine species, and 17 medications.

This review discusses the involvement of type I interferons in skin autoimmune and inflammatory diseases but reports no new clinical results.

This study found that women with female pattern androgenic alopecia have significantly higher levels of certain androgens and androgen sulfates compared to normal premenopausal women, suggesting markers for diagnosis and treatment efficacy.

The hair follicle structure is more complex than thought, with new findings on protein formation.

This study demonstrated that elevated glucocorticoid levels in transgenic mice led to pancreatic exocrine cells transforming into hepatocyte-like cells, resulting in pancreatic dysfunction.

This study found that the cuticle layer of hair contributes approximately 60% to bending stress, highlighting its significant role in the mechanical properties of hair stiffness.

Skin health and diseases are closely linked to metabolic processes.

This study found that peptidylarginine deiminase type III and trichohyalin are coincidentally expressed in the infant rat hair follicle, but trichohyalin deimination occurs after their expression during development.

This study found that integrating machine learning enhances the predictive accuracy of forensic DNA phenotyping from low template DNA, achieving high accuracy for traits like eye color, although challenges remain for admixed populations and complex traits.

This study found that switching juvenile mice from a high-fat, high-carbohydrate diet to a control diet optimally reduced hormonal imbalances and weight, with nutraceuticals offering partial support.

Botulinum toxins show promise in treating various conditions, but more research is needed for hair and scalp disorders.

This article provides an overview of conditions that can cause hair loss in dogs and cats and offers guidance on diagnostic approaches, but it presents no new research findings.

This study found that specific skin lesions are common indicators of pediatric rheumatologic diseases, potentially aiding dermatologists and rheumatologists in diagnosis when biopsies are challenging.

This study describes the PandaOmics platform, which uses AI and bioinformatics to identify new therapeutic targets and biomarkers for various diseases, demonstrating validation in laboratory and animal studies.
