Early hair loss in men could be a sign of non-cancerous prostate enlargement, and treating hair loss early might help prevent prostate issues later.

This study found that hair products used by Black women and children in the U.S. contain multiple chemicals associated with endocrine disruption and asthma, highlighting potential exposure disparities and a need for improved labeling.

This study found that stable regeneration of pigmented hairs in mice after severe wounding can occur when the wound is made during the anagen stage, influenced by Wnt and Kit signaling pathways.

This study observed that calcium hydroxylapatite can be successfully incorporated and retained in the dermis for at least six weeks after fractional laser treatment, with new collagen forming around it.

This review discusses epithelial-mesenchymal interactions in hair follicle development and their regulation by molecular signals, but reports no new results; the authors emphasize the need for further research to apply these findings clinically.

Certain immune cells in atopic dermatitis skin could be targeted for treatment.

This abstract discusses the broad scope of dermatology and aesthetic procedures, highlighting their significant multidisciplinary evolution within the health sciences, but it does not report specific study results.

Minoxidil users may experience hair discoloration, especially with long-term use and a family history of gray hair.

This article discusses a hypothetical model of androgenic hair trichophore composed of various chemical components, but it reports no new empirical findings; the authors emphasize the model's potential impact on hair cosmetics.

This study found that human scalp hair follicles can respond to corticotropin releasing hormone stimulation similarly to the classical HPA axis, including up-regulating cortisol production and activating neuroendocrine feedback loops.

This review discusses the use of natural products in cosmetic preparations for skin and hair care, but reports no new research results.

This study describes previously unknown immune characteristics of the normal human nail, highlighting its similarities to the hair follicle immune system and suggesting an immune privilege in the proximal nail matrix that both provides autoimmunity protection and presents infection susceptibility.

This review discusses recurrent implantation failure (RIF) in IVF, noting the lack of standard definitions or treatment protocols, and emphasizes the need for individualized treatment and further research.

This review discusses the role of immune privilege collapse in the pathogenesis of alopecia areata, emphasizing the potential for therapeutic manipulation of hair bulb immune privilege to offer new treatment options, and reports no new results.

This study found that both myo-inositol and metformin helped restore normal menstrual cycles in patients with PCOS, but myo-inositol appeared to be more effective in inducing pregnancy.

This review synthesizes current knowledge on eyelash hair follicles, highlighting gaps in understanding their biology and proposing future research directions; it reports no new experimental findings.

In this study, DHT was found to inhibit hair growth in mice by decreasing IGF-I production in dermal papillae through reduced sensory neuron stimulation.

This review examines studies on rosemary extracts for immune function, noting promising in vitro and animal evidence but highlighting a lack of human data.

This study found that co-delivery of minoxidil and caffeine in transfersomes with an optimized polysorbate formulation enhanced hair length and weight in vivo.

This article reviews skin disorders in Parkinson's disease, highlighting the potential of skin studies and stem cell research to advance understanding and treatment of the neurodegenerative disorder, without presenting new results.

This review explores the role of regulatory T cells in autoimmune skin disorders like alopecia areata and vitiligo, emphasizing unanswered questions and reporting no new experimental results.

This article discusses less commonly used and experimental treatments for vitiligo, focusing on therapies other than psoralen, but does not report new clinical results.

This study found that non-thermal plasma treatment increased epidermal thickness and dermal collagen density in mouse skin tissue without causing damage, potentially promoting growth factors and tissue remodeling.

This study found that keratinocyte stem/progenitor cell-conditioned medium significantly enhanced hair growth in mice and increased the proliferation of human hair follicle cells.

This review discusses adverse effects associated with pegylated IFN therapy for chronic hepatitis C and highlights the potential of new antiviral drugs to reduce side effects and improve treatment adherence, but reports no new clinical results.

Lifestyle changes and medical treatments can help manage infertility in women with PCOS.

In this study, an immortalized MSC line from human adipose tissue showed potential for applications in regenerative medicine and inflammatory diseases through production of active factors, demonstrated in vitro.

This study demonstrated that the biomimetic peptide PTP20 may help preserve hair pigmentation and reduce greying by enhancing melanocyte function and increasing melanin production in human hair follicles.

This study observed that differences in the expression of genes related to lipid metabolism may play a major role in determining wool fiber diameter in sheep.
