This study found that minoxidil combined with all-trans retinoic acid additively promoted hair growth in vitro by enhancing cell survival and reducing apoptosis compared to minoxidil alone.

This study observed that liposomes encapsulating minoxidil and PEP penetrate the skin at a slower rate but may reach deeper layers compared to a foam formulation.

This study found that pure linoleate deficiency in rats caused significant reductions in the accumulation of n-6 polyunsaturates and mild symptoms like growth retardation, compared to classical essential fatty acid deficiency.

This review discusses the complexities and uncertainties in the pathways and mechanisms for disulfide bond formation in multicellular organisms and reports no new experimental findings.

This study found that low concentrations of CBD promoted hair follicle growth, while higher concentrations induced hair follicle regression and increased cell death in an experimental setting.

This study suggests that the outer root sheath of human hair follicles may act as a "metabolic center," capable of synthesizing glucose from lactate, which supports glycogen metabolism.

In this study, hair damaged by permanent dye showed signs of recovery over time, with near complete restoration to its original state after eight weeks.

This review discusses the influence of androgens on hair and sebaceous growth, emphasizing that response may depend more on peripheral sensitivity than on hormone levels; it reports no new empirical results.

This study found that Annurca apple polyphenolic extracts reprogram hair follicle metabolism in mice, enhancing mitochondrial activity and keratin production while inhibiting some metabolic pathways.

This study found that TRP-hair essence significantly protected and improved the quality of human hair, particularly against heat stress, by enhancing cuticle health and maintaining hair color.

Hair graying may help prevent cancer by protecting stem cells.

Using a CO₂ laser for hair transplants improves the surgery and may become important in future hair restoration.

This study verified that a new straightening process involving a flat iron, ammonium thioglycolate, and hydrogen peroxide may permanently straighten wavy hair by eliminating disulfide bond distortions.

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

In this study, the authors concluded that a hydrolyzed eggwhite protein treatment promoted the reconnection of disulfide bonds in excessively bleached hair, after reduction and oxidation processes in permanent waving.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

This study investigated the effect of peracetic acid treatment on hair fiber structure and found that disulfide bond oxidation altered thermal properties while preserving the α-crystal structure, suggesting different stabilizing interactions in hair fibers.

This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.

This article discusses methods for diagnosing and managing diffuse hair loss and reports no new results; the authors emphasize systematic evaluation and the importance of psychological support.

This study used proteomic techniques to analyze human hair proteins, revealing keratin heterogeneity and identifying posttranslational modifications, such as cysteine trioxidation and methylation.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

This study observed that two patients treated with interferon α-2b and ribavirin for chronic hepatitis C experienced complete and reversible straightening of their natural curly hair, which recurred with treatment resumption.

This review discusses the structure and regenerative potential of hair follicles, highlighting their role in wound healing, stem cell populations, and keratin-based biomaterials, but it reports no new clinical results.

This article reviews the role of polyamines in hair follicle growth and discusses potential therapeutic applications but provides no new clinical results.

This study found that maternal Nano-Se supplementation in cashmere goats improved antioxidant status and promoted secondary hair follicle development in fetuses at 110 days.

This study found that protein extracts from human hair demonstrated significant antioxidant abilities, protecting human dermal fibroblasts from oxidative stress, suggesting potential for biomedical applications.

This study found that keratin film from human hair samples responded to damage from UV, bleaching, perming, and thermal treatments, making it a useful model for evaluating hair damage in product development.

This study developed a new proteomic method to identify and assess ancient hair proteins using only small amounts of sample, providing insights into hair protein alteration processes over time.

This review discusses the evidence for a cause-and-effect relationship between scalp condition and hair condition, and reports no new clinical results from trials.

This study reported that weekly intramuscular dexpanthenol may improve quality of life and satisfaction with hair appearance in women with female pattern hair loss, with no side effects observed.
