This review highlights the broad range of adverse effects associated with isotretinoin in acne treatment and examines strategies such as dietary supplementation and adjusted dosing protocols to enhance patient tolerability while maintaining efficacy.

This study found that local heterologous leukocyte-rich platelet-rich plasma improved distal skin flap viability in rats by reducing necrosis compared to the control group.

This study found that a nutritional supplement containing millet extract, pantothenic acid, L-cystine, and biotin significantly increased hair density, improved hair growth and appearance, and reduced hair loss by 59% in 112 healthy subjects with light diffuse hair loss over 12 weeks.

This study extracted water-soluble keratin particles from chicken feathers and verified their structural properties, observing no irritative potential on hen's eggs and positive physiological effects on human skin cells, suggesting their suitability for use on damaged or irritated skin.

In this study, researchers extracted soluble keratin proteins from chicken feathers and found they maintain structural integrity with potential uses for damaged skin, exhibiting no irritative effects in ex vivo settings on hen's eggs.

This study analyzes contemporary theories and practices to understand key factors influencing the development of the examined phenomenon, proposing trends and practical applications for researchers and practitioners, while acknowledging study limitations and suggesting future research directions.

In this study, researchers developed a polyphenol–amino acid nanozyme capable of controlled hydrogen peroxide delivery, which effectively activated hair follicles via oxidative stress in a mouse model, suggesting a potential non-pharmacological treatment for alopecia.

In this study, Saw Palmetto at a physiological dose partially inhibited 5-α-reductase and improved hormonal balance, inflammation, and mitochondrial function, with synergy observed when combined with Lycopene, L-Arginine, and Astaxanthin, enhancing male prostatic and endocrine health without endocrine side effects.

This study reported that Saw Palmetto, at a physiological dose, partially inhibits 5-alpha-reductase and, when combined with Lycopene, L-Arginine, and Astaxanthin, demonstrates a synergistic effect in restoring hormonal balance, reducing inflammation, and improving hair density, urinary flow, and oxidative biomarkers in related male health conditions.

This systematic review found that licensed hair gloss products in the UK provide significant cosmetic benefits like improved shine and smoothness, but 18% contain harmful additives, highlighting the need for stricter regulations and patient education on product safety.

This study explored the potential of the lysate and lipoteichoic acid from Lactiplantibacillus plantarum APsulloc 331261 to improve scalp seborrheic dermatitis by modulating inflammatory and lipogenesis pathways in vitro, suggesting potential as a natural treatment option.

In this study, reducing agents like ammonium thioglycolate, L-cysteine, and sodium sulfite in shampoo effectively decreased hair flyaway and frizz without causing damage, as no critical hair damage was observed in structural and tensile strength assessments.

In this review, the researchers reported that 5α-reductase inhibitors demonstrated neuroprotective effects and reduced dyskinesias in animal models of Parkinson's disease, suggesting their potential for repurposing to manage symptoms in men with PD.

This study found that consumption of dietary supplements and sports nutrition may lead to therapeutic and cosmetic improvements, benefiting skin, hair, and nails while potentially enhancing athletic performance.

In a study using mice, researchers observed that Cacumen platycladi fermented with Lactiplantibacillus plantarum CCFM1348—both as postbiotics and synbiotics—promoted hair growth, potentially by engaging the Wnt/β-catenin signaling pathway and enhancing growth factor expression.

This study found that a food supplement improved skin moisturization, elasticity, and thickness, reduced telogen hair density, and enhanced nail status in women with mild-to-moderate aging signs after 84 days.

In this retrospective cohort study, 87.1% of pediatric patients with chemotherapy-induced alopecia experienced clinical improvement after treatment with minoxidil or combination therapy with CYP, with the combination therapy showing greater hair thickness and minimal adverse effects.

In this study, researchers reported that both PRP and L-GF injections are effective in enhancing hair density and reducing recovery time post-transplantation in men with androgenetic alopecia, with L-GF showing slightly better but statistically insignificant results.

This study examined the vasorelaxant effects of two similar alkaloids, chloroquine and cinchonine, in a model of smooth muscle contractions induced by phenylephrine. Results are not reported in the abstract.

This study found that in individuals with alopecia, scalp microbial diversity decreased while Cutibacterium acnes abundance increased, and that treating Cutibacterium acnes-infected mice with Lactobacillus plantarum L30 improved hair follicle health and hair growth, suggesting a potential new treatment pathway for alopecia.

In this study, researchers found that while applying a lotion containing Lactiplantibacillus plantarum subsp. plantarum N793 did not improve hair density overall compared to placebo, it was effective in improving hair density among individuals with relatively mild hair thinning.

In this study on Sprague-Dawley rats, 0.60 mg/kg doses of L-Se-methylselenocysteine and sodium selenite were associated with liver toxicity and reduced sperm motility, while Se-enriched peptides showed no observable adverse effects up to 0.60 mg/kg.

This review provides a detailed overview of Hashimoto thyroiditis, discussing its epidemiology, risk factors, genetic and environmental contributors, clinical presentations, diagnostic methods, and treatment options, emphasizing the importance of personalized treatment plans due to varied causes and symptoms.

This study identified 18 significant metabolites and two enriched metabolic pathways, necroptosis and ABC transporters, in serum samples of acne patients with and without insulin resistance, potentially aiding in the clinical diagnosis and drug development for these patients.

This study found that human platelet lysate supported mesenchymal stem cell growth as effectively as fetal bovine serum, while fetal bovine serum was more effective for hepatocyte proliferation.

This article discusses the use of platelet concentrates in regenerative surgeries for periodontal and bone defects but presents no new clinical results, emphasizing their potential benefits over traditional methods.

This review discusses trichodynia, its potential causes, and treatment options, but reports no new clinical findings.

In this study, researchers developed enzymatic methods to isolate hair cuticle cells and remove the hair cuticle layer, finding that the harvested cuticle cells are thermally more stable and contain different structural proteins compared to descaled hair fibers.

This study observed that toothpaste and its active constituents promoted hair growth in mice, suggesting their potential for hair growth applications.

This study found that among Pakistani men with hair loss, the M type pattern was the most prevalent according to BASP classification.
