This study found that finasteride decreased plasma dihydrotestosterone levels and altered steroid metabolism, similar to the profile of male pseudohermaphrodites with inherited 5a-reductase deficiency.

This study found that using hair steroid profiling, dutasteride treatment led to reduced dihydrotestosterone levels and DHT/testosterone ratio in patients with male-pattern baldness.

This article reviews the history and current medicolegal challenges of doping in sports, focusing on FIFA's procedures and three urgent legal issues, but presents no new findings.

This case report describes the first dermoscopic evaluation of alopecia areata-like disease in a dog, where the condition mirrored human cases in terms of clinical presentation and treatment response.

A man's skin cancer improved and some of his hair grew back after treatment with a special light therapy and a medication.

This review assessed trichoscopic findings in folliculotropic mycosis fungoides of the scalp, reporting features like milky-red globules and distinct vascular patterns, but noted the predominance of small studies and the need for larger research to validate trichoscopy's diagnostic utility for this condition.

This study found that testosterone impacts hair follicles from different scalp regions differently in male pattern androgenetic alopecia, challenging the belief that occipital scalp follicles are androgen-insensitive.

Alopecia areata, a type of hair loss, may be passed through T cells and has genetic links, while treatments vary in effectiveness. Male pattern baldness can be treated with finasteride and is influenced by androgens in hair follicles.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

This article reports on a partial regrowth of scalp hair in a patient treated with extracorporeal photochemotherapy and interferon α 2a, but provides no new clinical outcomes.

This article reviews various hair growth and hair loss treatments, noting limited new developments since FDA-approved drugs but highlights recent cosmetic surgery and potential cell-based therapies; it reports no original findings.

The issue concluded that various skin conditions have different effective treatments and factors influencing them.

In this study, researchers found that changes in immune cell infiltration and immune-related gene expression may contribute to the immune microenvironment changes in male androgenetic alopecia.

This study found significantly higher levels of the protein ULBP3 in patients with alopecia areata incognita compared to other hair loss conditions and healthy controls, suggesting ULBP3's potential as a diagnostic marker for AAI.

This review discusses the interactions between immune cells and the skin epithelium and their impact on maintaining barrier function, emphasizing the potential to enhance epithelial barrier function in inflammatory diseases.

This review aims to help medical practitioners understand inferential statistical methods to critically evaluate clinical trial design and analyses, but it doesn’t present new research findings.

This study found that haploinsufficiency of SPINK5 can lead to Netherton syndrome when a single null mutation combines with homozygous G1258A polymorphisms, suggesting it acts as a genuine mutation affecting LEKTI function.

This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.

This quiz presents educational questions about alopecia areata, including its diagnosis and underlying mechanisms, but reports no new clinical outcomes.

This study found that T cytokeratins appear more gradually and with complex coexpression patterns in developing nail structures compared to the more abrupt transition in hair follicles.

This review discusses the clinical and trichoscopic features of lichen planopilaris and notes its potential underdiagnosis prior to hair transplant, but it reports no new findings.

60% of women who didn't respond to 5% minoxidil for hair loss showed significant improvement with a 15% minoxidil solution.

Using 5α-reductase inhibitors for hair loss in women doesn't increase cancer risk.

A man had an unusual type of hair loss that didn't match known patterns and didn't improve with treatment.

This study found that peribulbar lymphocytic infiltration can effectively differentiate between alopecia areata and androgenetic alopecia using T-cell infiltration patterns in skin tissue.

This case series evaluated the use of oral bicalutamide with low-dose oral minoxidil in women with female pattern hair loss who didn't respond to minoxidil alone, finding that 96.6% showed improvement after six months without adverse effects.

This study found that the internal structure and fracture patterns of hair vary among different mammal species, which could inform the development of keratin-based biomaterials for medical and cosmetic applications.

Androgens don't directly affect hair cell growth or protein production.

Cyclosporin doesn't stop hair loss.

This study observed that progressive frontal recession in postmenopausal women may exhibit features of fibrosing alopecia, suggesting a distinct reaction pattern from typical lichen planopilaris.
