A young man with an eating disorder had a life-threatening adrenal crisis due to an autoimmune condition, highlighting the need for better education on managing hormone treatments.

This study found that hair transplantation using the follicular unit extraction method significantly improved hair density and patient satisfaction in males with androgenetic alopecia, especially those younger than 33 and with less severe hair loss.

This article reviews over-the-counter products and active ingredients marketed for hair loss treatment, noting that many lack robust efficacy evidence except for minoxidil, which has temporary effects, and highlights the caution needed when recommending products to pregnant and breastfeeding women.

This study used advanced chromatographic and mass spectrometric techniques to develop a method for reliably detecting 17 hair growth compounds in consumer products, aiming to enhance regulatory compliance and ensure consumer safety against illicit compounds.

This study found that vitamin B6 injections over several weeks improved hair condition and reduced hair loss in some women with diffuse alopecia, while calcium pantothenate had no clear positive effect.

In this study, researchers observed that hybrid secretomes most effectively stimulated proliferation and stem cell markers for hair regeneration in hamster skin, while human secretomes strongly activated the Wnt/β catenin pathway, suggesting different underlying mechanisms among the tested formulations.

In this study, two patients with long-term total parenteral nutrition and no biotin intake experienced hair regrowth after biotin supplementation, suggesting biotin deficiency can lead to alopecia.

This study found that intralesional vitamin D injections in patients with alopecia areata resulted in mild effectiveness, with minimal hair regrowth observed in 75% of patients, and no significant change in SALT scores post-treatment compared to baseline.

This review discusses the use of nanocarrier technology in functional cosmetics to enhance skin penetration, increase ingredient stability, and allow codelivery of active ingredients, without reporting new clinical results.

In this case report, hair graying improved in a patient with male pattern hair loss after combined treatment with thulium laser energy and polydeoxyribonucleotide injections, suggesting potential therapeutic benefits.

This study found that a 6-week treatment with both brands of biotin and dexpanthenol significantly improved hair fall count and hair density in people with diffuse pattern hair loss, with no significant difference between the two brands.

This study found that exosome injections from human umbilical cord, with or without polydeoxyribonucleotide, promoted regrowth and repigmentation of white beard hairs and improved scarring in a 35-year-old man with refractory alopecia areata, suggesting potential as a minimally invasive regenerative treatment.

This study evaluated the safety and efficacy of Bio-Pulsed avian mesenchymal stem cell-derived small extracellular vesicles when applied topically, finding significant improvements in hair growth, skin rejuvenation, and regenerative microRNA presence among 60 human participants without adverse events.

This study found that intralesional methotrexate and triamcinolone acetonide were significantly more effective than Vitamin D3 for hair regrowth in patients with alopecia areata.

In this study, the authors explored the multifaceted connection between stress and stress-induced telogen effluvium, emphasizing how elevated cortisol levels and impaired microcirculation contribute to hair loss, along with potential interventions, including both medicinal and non-medicinal strategies like relaxation techniques and gentle care rituals.

The study discusses how stress can lead to telogen effluvium, a form of hair loss, by triggering hormonal imbalances and affecting microcirculation and hair follicle homeostasis. It highlights both medicinal and non-medicinal interventions, such as relaxation techniques and gentle care rituals, as potential treatment strategies.

This review reports that most active ingredients in Polish hair loss products lack scientific backing for their effectiveness against hair loss, with some even having counterproductive effects.

In this research, SEU-302, a newly developed covalent organic framework, exhibited significant antibacterial and wound-healing properties in vitro and in vivo, effectively eliminating Staphylococcus aureus and reducing inflammation under light activation, thereby showcasing its potential for therapeutic photodynamic applications.

In this study, researchers developed a novel delivery system using hyaluronic acid gels to encapsulate Huperzine A for Alzheimer's treatment, achieving extended release over 20 days and significantly improving pathology and behavior in mice, including enhanced memory and reduced neuroinflammation.

This study demonstrated that a microarray patch can deliver antibodies in a controlled and prolonged manner, maintaining their functionality after manufacturing and heat exposure, with successful pharmacokinetic proof-of-concept in rats.

In this double-blind study, a novel hyaluronic acid gel for lip augmentation was found to be as effective and safe as a commercially available gel, with similar adverse event profiles and high patient and investigator improvement ratings over six months.

This study found that adding microcapsulated pumpkin seed protein hydrolysate to aloe vera drinks improved antioxidant activity, taste, and shelf life, with chitosan-alginate microcapsules effectively inhibiting microbial growth during 30 days of refrigerated storage.
