This review explores how estrogens influence skin health and attractiveness in women, particularly with aging, but it reports no new clinical findings.

This study found that sudden hair loss in guinea pigs may serve as a potential biomarker for subacute exposure to mustard gas, and pre-treatment with N-acetylcysteine could prevent this hair loss.

This study reported that supplementing rat hair follicle stem cells with chick embryo extract enhanced their migration and proliferation, possibly promoting differentiation toward Schwann cells.

This review discusses the impact of hormones on female sexual function and dysfunction, highlighting the complexity and gaps in basic research, and reports no new clinical findings.

In this study, chick embryo extract enhanced neuronal differentiation and trophic factor expression in rat hair follicle stem cells, suggesting potential improvements for stem cell therapies in neurodegenerative diseases.

This review discusses the role of epithelial mesenchymal transition (EMT) in wound healing and tissue repair, highlighting its potential contributions to progenitor cell pools, but reports no new clinical findings.

Hair loss may be linked to cardiovascular health problems.

This study found that 10% Citrus aurantium peel oil significantly promoted hair growth in ICR mice by reducing the time needed for hair growth initiation and completion, and by increasing hair length, follicle diameter, and count, showing potential as a hair growth agent.

This study found that anagen hairs require less force to be extracted than telogen hairs in an in vitro pig skin model, indicating different anchorage mechanisms.

This study concluded that cyproterone acetate alone produced antiandrogenic effects on the female gerbil prostate, while ethinyloestradiol alone stimulated estrogenic activity, and their combination led to prostatic lesions.

This study found that in beagles with benign prostate hyperplasia, finasteride treatment increased blood volume and decreased vessel leakiness in the prostate's parenchymal zone as shown by dynamic contrast-enhanced MRI.

This article discusses the development of the regenerative medicine field based on stem cells' capacity for in vitro differentiation, rather than actual organ or tissue regeneration.

This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.

In this study, five patients with moderate hyperprolactinemia lacked symptoms, signs, or underlying causes, leading researchers to conclude that no further investigation or therapy was needed.

This study found that all four treatments—flutamide, finasteride, ketoconazole, and EE-CPA—significantly reduced hirsutism, but EE-CPA and flutamide appeared most effective, with varying effects on androgen levels and side-effect profiles.

This study found that flutamide, finasteride, ketoconazole, and EE-CPA all significantly reduced hirsutism scores, hair diameter, and hair growth rate in women with hirsutism over 12 months.

This review discusses the shared molecular and cellular processes in the early development stages of skin appendages like hair follicles, teeth, and mammary glands, reporting no new results.

This study found that frontal and frontoparietal hair recession is relatively common in women, especially after menopause, and may not indicate abnormal androgen metabolism absent other virilization signs.

This study found that 2% topical minoxidil solution was significantly more effective than placebo in promoting new hair growth in women with androgenetic alopecia.

This study found that increased dihydrotestosterone levels were observed in both androgenetic alopecia patients and controls, suggesting that follicle sensitivity to DHT may be more critical than DHT levels for alopecia development.

In this study, 1% procyanidin B-2 tonic significantly increased the number of total and terminal hairs on the scalp of male participants compared to a placebo after 6 months of use.

This article discusses the development of a transdermal testosterone patch for postmenopausal women to deliver physiological testosterone levels but reports no new clinical results, highlighting a need for long-term safety data.

This article discusses various repair techniques for hair transplants, emphasizing meticulous methods to improve cosmetic outcomes when donor hair is limited, but it presents no new clinical results.

This content only provides information about the JAMA Dermatology publication platform and reports no research results.

This report suggests that peripilar hair casts, potentially linked to modern hair styling or mild trichotillomania, may be more prevalent than currently reported.

This article highlights causes of otitis externa in small animals and proposes an investigative approach; it reports no new findings.

This study found that Wnt10a expression in odontoblasts increased with dental pulp regeneration and may be a potential non-cellular agent for inducing dental pulp regeneration with dentine-inducing capacity.

This article discusses objective methods for assessing hair loss and notes that most types of hair loss can regrow without treatment, but effective treatments for pattern or senescent alopecia remain unavailable.

Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.

Twisting hair weakens it, but strength can be recovered at low twist levels.
