This study found that hair follicle cells' growth in vitro is influenced by the concentration of androgens and antiandrogens, with papilla cells and outer root sheath keratinocytes showing distinct sensitivity.

This article reviews the management of excessive pre-ejaculate, highlighting case reports where 5-α-reductase inhibitors, such as finasteride and dutasteride, led to symptom resolution in patients reporting distress due to this condition.

This study found that the in vitro growth of hair follicle cells, particularly papilla cells and outer root sheath keratinocytes, is influenced by different concentrations of androgens and antiandrogens.

This review discusses the host genetic factors influencing COVID-19 susceptibility and pathogenesis, highlighting genetic variations that affect viral entry and immune responses, but reports no new experimental results.

This review discusses Amphiregulin (AREG) as a potential target for treating fibrotic disorders and cancer, highlighting its role in disease progression and promising results in preclinical studies and early trials.

This review discusses the potential use of spin traps in cosmetic products to limit reactive oxygen species generated by pollution, emphasizing the need for further research due to toxicity and regulatory concerns.

In this study, oral care products like foams and a spray, similar to tap water, improved salivary pH and oral clearance rates after exposure to Coca-Cola® in young adults, but no significant differences were found between these products and tap water.

This article discusses potential links between male balding, specifically androgenic alopecia, and severe COVID-19, suggesting that balding may serve as a biomarker for identifying higher-risk patients, but it reports no new experimental findings.

This review highlights the dual nature of Abrus precatorius Linn., known for its toxic compound abrin and medicinal potential. The research emphasizes its traditional uses, phytochemical diversity, and pharmacological effects, while calling for standardization and controlled trials to ensure safety and efficacy in therapeutic applications.

This review article reports that oxidative stress is a key mechanism in the development of androgenetic alopecia, interacting with genetic and hormonal factors to damage hair follicle cells and potentially informing future treatment strategies.

This review highlights morphological factors contributing to age-related alopecia and suggests further research to understand and potentially mitigate cellular aging processes affecting hair quality.

Miliacin may help prevent hair loss and improve hair growth in mice with a condition similar to human baldness.

This study found that applying ostrich antibodies against DHT and 5α-reductase generally promoted hair growth in 16 of 17 participants with androgenetic alopecia after about three months of treatment.

This review examines targeting the JAK-STAT pathway in inflammatory skin diseases, highlighting existing JAK inhibitors and potential developments, but presents no new experimental or clinical results.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

This review explores the potential of phytotherapeutic molecules and oxidative inhibitors as novel anticancer and chemopreventive agents, reporting no new clinical results while suggesting their promise in drug development.

In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.

This study suggests that nerve growth factor plays a crucial role in the stress-induced termination of hair growth in mice, and its antagonism might offer a therapeutic approach to mitigate stress-related hair loss.

This study found that the retinoid all-trans retinoic acid induced a catagen-like stage in human scalp hair follicles, suggesting upregulation of TGF-beta2 as a contributing mechanism.

This study in mice demonstrated that stress or nerve growth factor injection increases sensory neuron activity related to skin innervation, suggesting a strong connection between stress perception and neurogenic skin inflammation.

This study found that brain-derived neurotrophic factor (BDNF) inhibited hair shaft elongation and induced premature catagen development in cultured human hair follicles, partially through transforming growth factor β2.

This review considers oxidative stress effects on hair aging and emphasizes the need for dermatologists to recognize and treat factors affecting scalp and hair health, but it provides no new clinical findings.

Protein ubiquitylation is crucial for controlling stem cell functions and could be targeted for cancer treatment.

In this study, CD4+CD25+FoxP3+ Regulatory T cells were found to reduce TGF-b1 induced lung fibrosis and fibrocyte accumulation in mice, partly by suppressing fibroblast growth factor 9.

In this study, l-Ascorbic acid 2-phosphate was found to stimulate hair follicle growth in vitro by promoting IGF-1 expression via the PI3K pathway.

This study found that stressed dermal fibroblasts significantly increased dopa oxidase activity in melanocytes from hair, skin, and eyes, suggesting the involvement of fibroblast-derived factors like basic Fibroblast Growth Factor.

This review examines various immunomodulatory therapies for cutaneous lymphoma and notes that they are most effective in the disease's early stages.

This study found that hair follicles play a significant role in regulating skin barrier function, with disruptions in the upper hair follicle affecting the epidermis, influencing processes like desquamation and sebum release, and leading to cell movement into the epidermis.

This review summarizes the historical and evolving treatments for vitiligo, highlighting that combining medical and surgical approaches may enhance repigmentation outcomes, though more research and new protocols are needed.

This study found that platelet factor 4 in platelet-rich plasma suppresses human hair follicle growth and alters related gene expressions, suggesting potential implications for its use in hair loss treatment.
