This study found that cysteine and arginine are crucial for hair growth in hair follicles, with cysteine affecting hair fibre diameter and arginine involved in protein incorporation and energy metabolism.

In this study, US-based experts reached a consensus on treating adults with severe alopecia areata, recommending oral Janus kinase inhibitors as the primary long-term therapy, while also suggesting supplemental treatments like minoxidil and corticosteroids, with a call for more research on specific patient subpopulations.

This study found that Plinest injections improved skin hydration and elasticity in the face, neck, and décolleté and were well-tolerated, with high patient satisfaction over a 4-month follow-up.

This review concludes that methotrexate remains an effective and safe first-line treatment for various inflammatory and immune-mediated skin conditions in children, despite the rise of biologic therapies.

In this study, combining Polynucleotides High Purification Technology with hyaluronic acid significantly reduced atrophic post-acne scar areas and improved Goodman-Baron scores in a majority of treated patients over six months, reaffirming the approach's beneficial effects in a real-world outpatient setting.

This study demonstrated the usefulness of fully implantable loggers in measuring heart rate and sub-blubber temperature in captive harbour seals, with findings suggesting lower heart rates during molting and differences in temperature regulation between adults and sub-adults.

This study assesses the potential of exosomes as a therapeutic option for androgenetic alopecia, examining their mechanisms and effectiveness. The authors conducted a systematic review of existing research to explore how these extracellular vesicles might stimulate hair growth and restore follicle function.

This study concluded that advancements in understanding the immunological mechanisms of alopecia areata have led to promising therapies, particularly JAK inhibitors and novel drug delivery systems, but further research is needed for clinical application.

This review highlights the inconsistent and often insufficient global coverage of cranial prostheses for medical hair loss, with variations depending on healthcare system models and a general lack of standardized recognition as medically necessary devices.

In this case report, a 45-year-old man with treatment-resistant androgenetic alopecia experienced hair regrowth during oral bicalutamide treatment but also suffered adverse effects leading to discontinuation, highlighting the need for further studies on the safety and role of androgen receptor blockade in hair loss.

Nutraceuticals like Viviscal and Nutrafol can help treat hair loss when used with standard treatments.

This study found a significant association between baldness patterns, particularly vertex and early-onset baldness, and an increased risk of prostate cancer.

Infections and missed treatments trigger flares in alopecia areata patients on JAK inhibitors.

This case report describes an 85-year-old woman who developed localized telogen effluvium, a form of temporary hair loss, three months after Mohs micrographic surgery for basal cell carcinoma on her scalp, with complete hair regrowth achieved through minoxidil therapy within ten months.

In this study, a qualitative review of research suggested that regular moderate physical activity and healthy lifestyle habits may help manage male androgenetic alopecia by improving metabolic and hormonal balance, although excessive exercise could worsen hormonal effects linked to the condition.

This study found that in stretch-mediated tissue expansion, fibroblasts adopt an embryonic-like, low-collagen state that enhances epidermal stem cell renewal, supporting coordinated skin expansion crucial for reconstructive surgeries.

This review found that solar radiation, pollution, and trace metals cause significant damage to human hair, with factors like UVB radiation primarily affecting light-colored and bleached hair; most data were derived from in vitro and ex vivo simulations.

This study found that UV radiation exposure during a simulated Brazilian summer caused more significant mechanical damage to natural hair than bleaching, although both caused comparable structural alterations, with double bleaching leading to the most severe protein degradation.

This study found that among Australians aged 15 and older, the lifetime prevalence of alopecia areata ranged from 1.2% to 2.3%, and the point prevalence ranged from 0.9% to 1.4%, emphasizing the need for better awareness and education about treatment options.

This study provides a framework for understanding different types of alopecias based on immune privilege collapse at specific follicular sites, revealing distinct patterns in immune effector programs and stromal influences depending on the alopecia type.

In this study, researchers analyzed English primary care data and found that long-COVID symptoms such as fatigue, cognitive, and mobility impairments persisted at 6–12 months after infection, though these effects were generally less pronounced following the later pandemic wave.

This research highlights that migraine in midlife women, during perimenopause, often becomes more frequent and intense, with evolving characteristics like migraine aura, and is associated with increased stroke risk, especially with hormone therapies.

This study found that the TYK2 inhibitor deucravacitinib did not significantly improve hair regrowth in patients with alopecia areata compared to placebo, suggesting it may not be effective for this condition. No new safety issues were identified.

This systematic literature review found that exosome and PRP therapies show promise as effective, minimally invasive options for treating androgenetic alopecia, with clinical benefits potentially superior to or complementary to minoxidil, although standardization and larger clinical trials are needed to confirm long-term safety and efficacy.

This review discusses the mechanisms, scientific support, and FDA clearance of photobiomodulation mask devices but reports no new research findings.

This study systematically reviewed the use of topical testosterone products such as creams, gels, and patches, finding they effectively raise serum testosterone but pose significant systemic risks like acne and gynecomastia, necessitating careful medical oversight.

This narrative review highlights the distinct needs of pediatric hair care, emphasizing gentler formulations due to differences in children's hair physiology, structure, and barrier function, and calls for targeted regulations and research due to limited safety evidence.

In this narrative review, researchers synthesized current evidence on topical metformin's potential benefits for various skin conditions, citing primarily preclinical studies that highlight its anti-inflammatory, antioxidant, and regenerative properties, although clinical translation requires further rigorous trials.

This preclinical study found that Mesenchymal Stem Cell-derived Conditioned Media formulations were safe and effective in rat and mouse models for treating chemotherapy- and radiation-induced oral mucositis, demonstrating improved tissue regeneration and healing, most notably at higher concentrations.

This source discusses how radiotherapy-induced skin fibrosis, a chronic side effect affecting cancer survivors' quality of life, is driven by ongoing inflammation and fibroblast activity, and emphasizes the need for comprehensive dermatologic management and better diagnostic tools.
