This study found that the GPR39 receptor plays a novel role in accelerating wound healing in mouse skin, although it is not essential for skin development or homeostasis.

New method measures minoxidil concentration faster, more accurately, and automatically.

This study developed a faster method to analyze fatty acid ethyl esters in human hair, potentially distinguishing alcohol consumption levels more efficiently.

This study identified previously unknown phase I and phase II metabolites of finasteride in human bile and urine using a specialized bile collection technique and advanced mass spectrometry analysis.

Detecting steroid esters in cattle hair is inconsistent and influenced by sampling factors.

This study concluded that the best approach for detecting Androsta-1,4,6-triene-3,17-dione administration in horses is monitoring the metabolites M1b or M4 in urine, detectable up to 77 hours post-administration.

This study reported species and demographic differences in alopecia rates among macaques, with the highest rates in pigtail macaques and noted age-related improvements in alopecia scores.

A new method was developed to accurately measure enzyme activity related to prostate health.

Cortisol and cortisone release from hair increases in steps over time during incubation.

This study found that the BASP classification system for pattern hair loss showed better reproducibility and repeatability compared to the Norwood-Hamilton classification.

This study found that serum PSA levels are higher in hirsute women and can be significantly reduced by antiandrogen treatment, suggesting PSA as a marker of androgen action in females.

This study developed and validated a reliable method to measure finasteride levels in human plasma, which was successfully used to assess its pharmacokinetics after a 5 mg dose in healthy volunteers.

This literature review found that chemical peels are effective for treating various skin conditions in men, such as acne, rosacea, and photodamage, and noted that men may require more treatments or stronger peels due to their skin's characteristics.

This study developed and validated a sensitive liquid chromatography–mass spectrometry method to measure aristolochic acid‐I in rat plasma, successfully applying it to pharmacokinetic research.

This paper discusses a case where intralesional cidofovir successfully treated squamous cell carcinoma without systemic toxicity, but surgical excision remains the standard for curative treatment and margin evaluation.

This study found that the promoter region of the sheep KRTAP11-1 gene drives specific transcriptional activity in wool follicles, suggesting it may regulate hair keratinocyte specificity.

This study found that regio-specific hydroxylation of cyclosporine A in Sebekia benihana is mediated by the cytochrome P450 hydroxylase CYP-sb21, suggesting potential biotechnological applications for hair growth promotion without immunosuppressive effects.

This study determined that a total testosterone concentration of ≥5.1 nmol/L identified androgen-producing tumors in women with severe hyperandrogenemia, while a lower threshold of ≥2.2 nmol/L was found for diagnosing pathologic hyperandrogenism in postmenopausal women.

This article reviews milestones in understanding psychosomatic factors in dermatology and outlines clinical criteria for identifying them, but it presents no new research data.

This study developed and validated a method using hair samples to simultaneously detect bisphenols and parabens, enabling the quantification of these endocrine disruptors in a hospital population’s hair.

This review discusses diagnostic and management challenges of polycystic ovary syndrome in children and adolescents and reports no new clinical results; it emphasizes early intervention when a provisional diagnosis is suspected.

This study identified two high sulfur protein genes, B2E and B2F, in rats, which are expressed in hair cortical cells during anagen and contribute to hair fiber production.

Male hormones control a specific gene in hamster skin, with different hormones having varying effects.

This study developed a new method using liquid chromatography-tandem mass spectrometry to measure multiple steroid hormones in hair, requiring significantly fewer strands than previous methods, with high accuracy and precision.

This study found that a modest increase in dietary zinc over six months resulted in a detectable increase in sulfur and zinc counts in individual hairs, suggesting a non-invasive method to monitor zinc intake effects.

In this study, Bioactive Collagen Peptides supplementation increased hair follicle cell proliferation and improved hair thickness in healthy women over 16 weeks compared to a placebo.

This study found that finasteride 1 mg improved hair growth in 85.7% of Korean men with androgenetic alopecia over five years, with varying effectiveness depending on the type of hair loss.

This study reported that direct brow lift surgery provided excellent and long-lasting results in bald men with high anterior hairlines, despite visibility of the scar in a few cases.

Coconut oil can penetrate hair better than mineral oil, potentially protecting against damage.

Minoxidil does not specifically target any hair follicle cells.
