In this study, DHT was associated with increased production of proinflammatory cytokines IL-6 and TNF-α in cultured sebocytes, suggesting a role in acne pathophysiology beyond sebum production.

This article describes acute and chronic telogen effluvium, highlighting the importance of differentiating them from androgenetic alopecia for accurate diagnosis and treatment strategies but includes no new clinical research findings.

This research discusses a novel imaging approach in live mice to study stem cell and niche interactions in tissue homeostasis and reports no new results.

This study found that cooling hair grafts during transplantation did not significantly improve the survival or growth rates of hair follicles compared to room temperature storage.

This review proposes a classification system for childhood hair loss based on clinical appearance, age of onset, and associated symptoms, but reports no new clinical results.

This study found that arachidonic acid may promote hair growth by enhancing dermal papilla cell function and stimulating the anagen phase in C57BL/6 mice.

This article discusses various aspects of trichoscopy for diagnosing hair and scalp disorders and reports no clinical results, offering guidance and highlighting pitfalls for better application of this tool by dermatologists.

This study found that women with polycystic ovary syndrome had significantly higher serum and intrafollicular levels of anti-Müllerian hormone compared to normovulatory women, indicating a potential marker for ovarian hyperstimulation syndrome risk.

This article discusses using body and beard hair for hair restoration and reviews the indications, techniques, and risks involved, but reports no new clinical results.

In this study, topical tofacitinib significantly increased hair regrowth in mice compared to minoxidil or vehicle, potentially due to elevated VEGF levels and reduced inflammation.

This study found that Scutellaria baicalensis extract and its main component baicalin inhibited androgen activation signaling and promoted proliferation of human dermal papilla cells, suggesting potential use in treating androgen-associated disorders.

This study observed that hair follicles in hair loss patients had increased levels of Propionibacterium acnes, potentially linked to elevated immune response gene expression in miniaturized hair follicles.

This review discusses the potential of herbal treatments like Saw palmetto, Green tea, and Rosemary as alternatives to conventional drugs for androgenetic alopecia, noting that these herbs may inhibit the 5-alpha-reductase enzyme and reduce hair loss with fewer side effects.

In this study, tofacitinib treatment in a male patient with alopecia areata led to significant hair regrowth and improvement in nail dystrophy symptoms, restoring finger function within 10 months.

This study found that using an electrical microneedling device enhanced the penetration of liposomal melanin-fluorescein into hair structures and widened the follicular infundibulum in ex vivo human skin models.

This study found that only minoxidil encapsulated in cationic vesicles significantly promoted hair growth in mice, likely due to its higher retention on the skin.

This study describes the anatomy of arrector pili muscles in scalp hair follicular units, proposing a model where a single muscle structure is shared by all follicles within a unit.

This review discusses advancements in cell culture techniques for hair growth treatments and provides insights into the potential and challenges of follicular cell implantation, reporting no new clinical results.

This study suggests that finasteride may affect hair follicle growth by altering the expression of caspases and XIAP, potentially regulating the anagen phase of hair growth.

This study found that Hoxc13 gene expression, influenced by melatonin, was associated with hair follicle activity in Cashmere goats, with in vitro evidence suggesting effects on genes relevant to follicle development.

This review discusses the use of laser and flashlamp technology for unwanted hair removal and reports no new clinical results, highlighting challenges with light-colored hair and treatment safety for darker skin tones.

This study found that preserving hair micrografts in an enriched storage medium for five hours significantly increased their survival rate compared to those stored in saline.

This study reports that finasteride treatment in men with androgenetic alopecia appears to restore caspase and XIAP expression in hair follicles to levels similar to those in individuals without the condition.

In this study, treatment with finasteride 1 mg/day for five years significantly reduced the likelihood of further visible hair loss in men with androgenetic alopecia compared to placebo.

This review discusses the potential uses of 5α-reductase inhibitors for conditions ranging from benign prostatic hyperplasia to skin disorders like acne and male pattern baldness, but it reports no new clinical results.

This study observed that human hair follicles with a completely destroyed bulb can regenerate after being grafted onto immunodeficient mice, entering a shortened dystrophic telogen followed by anagen phase.

This study found that feeding mice high levels of dietary vitamin A increased WNT signaling, which activated hair follicle stem cells and may have accelerated alopecia areata progression.

This review examines the recent progress in using bioactive molecules for skin regenerative medicine and reports no new clinical results; the authors suggest this method could become a promising strategy for in situ skin regeneration.

This study found that dissecting folliculitis is more common than previously thought in Taiwan, with obesity possibly linked to higher severity of this condition, but smoking not associated.

This study reports that nonscarring diffuse hair loss in women is most common in the 21-40 age group, with low serum ferritin, vitamin B12, and vitamin D3 levels contributing to its pathogenesis.
