This study identified two potent 5α-reductase inhibitors from Tectona grandis leaves, and suggests that ethanol is a preferable solvent for extracting these compounds, which are potential ingredients for hair loss treatments.

This study found that some white or grey hairs can naturally regain pigmentation, suggesting hair greying may be reversible in certain conditions linked to psychological stress.

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 developed a method to automatically detect androgen receptor nuclear translocation in dermal papilla cells using fluorescence markers and image analysis, finding that the receptor's nuclear signal peaks about 20 minutes after DHT exposure.

This study developed and validated a reliable RP-HPLC method for accurately quantifying dutasteride in pharmaceutical formulations and bulk pharmaceuticals using a Shiseido C18 analytical column, demonstrating precision, accuracy, and sensitivity across a concentration range of 10 to 22 ppm.

This study identified genetic, biological, and technical factors that influence circRNA expression in the human brain, connecting these factors to potential genetic risk for diseases like schizophrenia and type II diabetes.

This study reports that among men, skin surface hydration and pH change with age, but transepidermal water loss and sebum production show less variation.

This study developed a mouse model to monitor hair follicle cycling macroscopically through live bioluminescence imaging, enabling detailed analysis of hair cycle and propagation dynamics influenced by environmental factors.

This study suggests that elevated copper levels in domestic tapwater, exacerbated by its aggressive properties, likely contribute to green hair by damaging the cuticle and increasing copper uptake.

This review discusses various approaches to skin tissue engineering and the evaluation of skin substitutes, highlighting the need for more objective assessments and improved understanding of skin regeneration.

In laboratory models of human skin, this study found that treating with resveratrol significantly increased glutathione levels, potentially enhancing the skin's antioxidant defenses.

This study identified flavonoids and phytosterols in a medicated cosmetic cream developed for androgenic alopecia and proposed methods for their identification and quantification.

This study identified ten compounds from Eclipta prostrata, with some displaying potent inhibitory effects against α-glucosidase and acetylcholinesterase enzymes.

Accurate method measures finasteride levels in human plasma using gas chromatography-mass spectrometry.

This study found that porcine skin serves as a reliable model for studying drug absorption into human hair follicles, showing a strong correlation in follicular drug absorption between porcine and human skin.

The researchers reported that hair offers a measurable protective barrier against UVB and UVA radiation, which increases with hair density, thickness, and melanin content, suggesting a role in skin cancer prevention.

This study observed phenotypic diversity in hair loss among Japanese individuals homozygous for the LIPH c.736T>A mutation and suggests that differences in hair thickness may contribute to varying severities.

This study observed variability in hair density and types across different scalp areas in cadaver biopsies, providing reference values that could aid in diagnosing hair disorders in Asians.

This study found a strong correlation between the Sinclair Scale and cumulative hair thickness density, allowing the estimation of the Sinclair Scale from trichoscopy-derived statistics.

This study explored a multidimensional approach to examine body hairs' physico-chemical properties, potentially supporting their use over scalp hairs in forensic and intoxication studies.

This study found that nearly all nurses caring for chemotherapy patients showed detectable levels of cyclophosphamide in their urine, indicating significant occupational exposure to this antineoplastic drug.

The researchers in this study suggest that using plant-based hair serums, which combine herbs and botanical phytochemicals, can enhance therapeutic benefits for hair and skin, offering improvements like deep nutrition, skin suppleness, and UV protection compared to individual herb use.

This study reports that fly blood progenitors in a long-term organ culture model undergo symmetric cell divisions influenced by cell size and orientation, with infection triggering changes in cell differentiation kinetics.

This study found that inhibiting mTORC2 in glioblastoma cells reduced DNA repair and increased apoptosis, highlighting its potential role in cancer cell survival and DNA damage response.

This study observed that skin pigmentation significantly attenuates bioluminescent signals in C57Bl/6 mice, complicating quantitative optical imaging and requiring consideration in experimental design.

This study found that in the Thai population, hair density varies by scalp location and decreases with age, and that Asians generally have lower hair density compared to Caucasian and African populations.

The study observed that Americans of Hispanic descent have a statistically significant higher hair density than individuals of African descent but lower than Caucasians, which may assist in diagnosing and researching hair disorders.

This study found that using very-low-dose oral minoxidil (0.25 mg/d) led to improvement or stabilization of hair parameters in 40% to 60% of men with androgenetic alopecia, although results were not statistically significant for the overall group.

Method accurately measures finasteride in tablets using finasteride-BSA interaction.

In this correspondence, researchers reported that very-low-dose oral minoxidil (0.25 mg/d) showed some effectiveness in stabilizing trichoscopic parameters in male androgenetic alopecia. However, their analysis suggests that higher doses (2.5–5 mg/d) may lead to better clinical responses with similar rates of adverse events.
