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

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 case report describes an atypical presentation of alopecia areata in a 53-year-old postmenopausal woman, which may resemble frontal fibrosing alopecia and complicate diagnosis.

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 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.

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

This case report highlights a rare instance of CD8-positive hypopigmented mycosis fungoides causing alopecia areata-like changes, emphasizing the necessity of scalp biopsy in such presentations.

This study developed and validated a highly sensitive LC-MS/MS method for detecting multiple steroid hormones in urine and serum/plasma, demonstrating its potential for use in large-scale biomonitoring studies.

This study describes a new method using high-resolution mass spectrometry for analyzing multiple steroids in human scalp hair, with newborn hair showing the highest steroid concentrations among examined age groups.

This study identified the major component of katuk leaf water extract as an alkaloid compound with a molecular mass of 406.3131 m/z, named (S, S)-5,5′-amino-4,4′-dihexyl-propyldihydropyrazol-3,3′-one.

This study found that the methanolic extract of Carthamus caeruleus roots significantly reduced inflammation, promoted wound healing, and enhanced hair growth in experimental models, supporting its traditional use in Northern Algeria as a skincare remedy.

This study developed an advanced HPLC-ESI-ion trap MS(n) method for the structural identification of cyclosporin A analogs CyA and CyC and reported the first MS(n)-aided identification of a new CyA analog.

This study found that improved testosterone measurement using LC-MS/MS in women with PCOS revealed a stronger correlation between hyperandrogenism and insulin resistance than previously detected.

This study found that standardized scalp massages may help stabilize or regrow hair in individuals with androgenic alopecia, as perceived by the participants themselves.

This study successfully established and validated a method using LC-MS/MS to measure multiple androgens in plasma, finding that individuals with acne had higher levels of certain androgens compared to those with obesity.

This study found that higher levels of dihydrotestosterone in the parietal region of the scalp may correlate with the clinical presentation of androgenetic alopecia.

This study found that the proposed LC-MS/MS method accurately quantified the drug content in split tablets of finasteride and terbinafine, revealing significant variability and suggesting that non-scored tablets should not be split.

This study reported the development of a workflow that combines SIMS and X-ray elemental mapping techniques for multimodal imaging at the single cell level, successfully applied to visualize elements, metals, and lipids in porcine skin without loss or delocalization.

This review examines the potential of regulatory T cell-based therapies to transform treatment across various medical specialties by promoting immune tolerance and tissue repair, but it reports no new clinical results.

In this study, 8-week hair loss management combined with aroma scalp massage did not significantly change hair thickness or density but improved scalp moisture and subjective satisfaction among 16 participants aged 20–50.

This study found that the FTO gene variants rs17817449 and rs1421085 were significantly associated with PCOS susceptibility, and rs8050136 was linked with hair loss and high BMI in women with PCOS in western Saudi Arabia.

This study demonstrated that using finasteride impurity as a non-isotopically labeled internal standard in paper spray ionization–mass spectrometry can effectively and efficiently measure finasteride tablet dissolution, achieving results comparable to high-performance liquid chromatography.

This study developed a high-throughput method that identifies bioactive chemicals influencing DHT production in prostate cancer cells, with potential nutraceutical candidates including fucoxanthin, phenethyl caffeate, and Curcuma longa L. extract.

This study developed a mask-cream containing Sabal palm extract and Sophora japonica tincture for androgenic alopecia prevention and treatment, establishing optimal production techniques using a reverse emulsion method.

This study found that the metabolic profile of finasteride in pigs closely matches that of humans, supporting the use of pigs for studying human drug metabolism.

This case report illustrates the diagnostic challenges and importance of early detection in primary vitreoretinal lymphoma, highlighting a successful treatment outcome with systemic chemotherapy in preventing CNS progression.

This study developed a validated gas chromatography–tandem mass spectrometry assay to assess sex steroid hormones in cerebrospinal fluid, finding substantial levels of DHEA, androstenedione, and testosterone, with strong correlations to serum levels, providing insight into sex steroid dynamics in the human CNS.

This study analyzed the effect of ginger hair masks and found that a significant portion of salon customers had never used them despite experiencing hair damage.

This study found that a short- to medium-term microneedling treatment for a male patient with androgenetic alopecia resulted in a 75% improvement in hair growth and color, and a 50% improvement in hair thickness, with sustained results for five months post-treatment.

This study concluded that two different pharmaceutical formulations of finasteride were bioequivalent in terms of rate and extent of absorption based on pharmacokinetic evaluations in a randomized crossover study with 38 volunteers.
