This article describes a new method for staining hair fibers that visualizes keratin filaments without the need for OsO4 fixation or sulfur bond breakage, but it provides no new experimental results beyond the method itself.

This study clarified and quantified the concept of hair transparency using a validated mathematical model based on measurable hair properties and consumer perception data from stylists in Japan and China.

This review examines various methods for assessing hair growth in women, highlighting the usefulness of the mFG visual scoring method for diagnosing hirsutism despite its limitations.

This study developed and validated a high-performance liquid chromatographic method for identifying finasteride and its degradation products, showing excellent resolution and sensitivity under various decomposition conditions.

This article reviews methods for standardizing patient photographs in hair restorative surgery and reports no clinical findings; it highlights the importance of consistent photographic techniques.

This study observed increased proliferation and certain gene expressions in dermal papilla cells exposed to an 808 nm laser diode array at doses above 0.5 J/cm².

This study found that 830 nm LED light effectively treated post-inflammatory erythema and hyperpigmentation, while both 830 nm and 590 nm LEDs prevented post-inflammatory erythema.

This study reported that a 3D-printed LED photobiomodulation device is technically and financially feasible, but requires further experimental and clinical testing before being used in human healthcare.

This study measured plasma testosterone glucosiduronate levels and found no overlap in those with hyperandrogenism compared to normal females, despite normal testosterone and dihydrotestosterone levels in half of the affected patients.

This study suggests that using trichotillometry to establish the normal range of shear strain for different hair types could inform diagnostic and treatment decisions for various hair conditions.

This study presents a novel assay that allows for the simultaneous measurement of various androgens and 5α-reductase inhibitors in male serum, facilitating research into the biochemical effects of these inhibitors.

This study found that handheld dermoscopes with polarized light can be beneficial in assessing treatment success in alopecia areata by revealing changes in trichoscopic features like thinning hairs and short terminal hairs.

This study developed a simple and reliable technique to quantify hair loss in mice, potentially enhancing assessment and comparison of new alopecia therapies in preclinical research.

In this study, researchers used trichoscopy to establish standardized findings for normal hair and scalp characteristics in 360 healthy males, noting significant age-related differences in hair diameter variability and identifying potential pathological indicators like colored dots and scarring not present in healthy individuals.

This study analyzed dosimetric quantities in x-ray microbeam radiation therapy and found that the peak-to-valley dose ratio decreases with depth in the irradiated object.

This study found that OPC-17116 can be reliably detected in hair, suggesting it can serve as an index of drug exposure and a time-marker in hair analysis.

This study reports that quantitative trichoscopy, while noninvasive and convenient, provides less accurate hair density data compared to invasive histopathologic examination, which was demonstrated in a sample of adult Chinese individuals without alopecia.

This review discusses the role of scalp imaging techniques in trichology for researching drug delivery and toxicology, without presenting new clinical results.

This study developed a validated method for analyzing minoxidil in hair care cosmetics, demonstrating good precision and recovery rates.

Combining scalp photos with hair density and caliber measurements gives a more accurate assessment of hair loss.

This article discusses using high performance liquid chromatography to optimize mobile phase composition for separating synthesis products of Finasteride, without reporting new clinical results.

This study found that arylsulfatase enzymes in hair follicles can convert the active form of minoxidil back to its inactive form, potentially affecting its effectiveness in treating androgenetic alopecia.

This study proposes a new mathematical model, the Harmonic Mean equation, for precisely quantifying nuclear pleomorphism in breast cancer grading, showing high performance with accuracy, recall, specificity, precision, and F1-score metrics.

This article discusses using the ImageMeter mobile app to calculate scalp area for PRP treatment in androgenetic alopecia, reporting no new clinical results.

This review examines the molecular effects of photobiomodulation therapy, particularly its influence on gene and protein expression related to inflammation and cell functions, but reports no new clinical results.

This study developed a precise and simple HPLC method for estimating tamsulosin and finasteride simultaneously in pharmaceutical forms, demonstrating good precision and potential usefulness for combined dosage analysis.

This study developed a precise and sensitive HPLC-MS/MS method for analyzing the pharmacokinetics of perospirone hydrochloride in human plasma, establishing it as suitable for clinical studies.

This study found that line-field confocal optical coherence tomography correlates well with histopathological and dermoscopic findings in alopecia areata, suggesting it could be a useful diagnostic and monitoring tool for the condition.
