This study found a significant positive correlation between hair thickness and growth rate, with a notably slower growth rate observed in men with male pattern hair loss compared to healthy controls.

This study used LC-HRMS to detect undeclared pharmaceutical ingredients like minoxidil and finasteride in hair serums, finding risk to public health due to their toxicological properties and advocating for manufacturer transparency.

This study developed a straightforward HPTLC method for detecting nicotine and cotinine in human plasma and urine, concluding that liquid-liquid extraction with methanol: chloroform: ammonia achieved optimal separation and is applicable for forensic analysis of lethal nicotine intoxication.

This study found that using sulfur 35 L-cystine for measuring linear hair growth is accurate, cosmetically acceptable, and safe in both experimental animals and humans.

This study identified a novel mutation and confirmed a previous mutation in the LIPH gene in a woman with autosomal recessive woolly hair, expanding the mutation spectrum for this condition.

This study suggests that lipin-1 plays a crucial role in keratinocyte differentiation by modulating protein kinase C activity through diacylglycerol levels, with implications for skin biology.

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

This study validated an HPLC-UV method to detect minoxidil in cosmetic products and found that 2 out of 9 analyzed products contained minoxidil, despite international regulations banning its inclusion due to potential systemic absorption.

This study introduces a novel non-invasive method called "differential stripping" to quantify the penetration of topically applied substances into hair follicles.

Minoxidil given intravenously caused small changes in diastolic blood pressure and increased heart rate at higher concentrations in patients with high blood pressure.

This study reports that an electrochemical biosensor using a gold and palladium-modified electrode effectively detects levodopa and uric acid in various samples, offering improved performance over previous electrodes.

This research explores developing liposomal formulations to enhance the delivery of difficult-to-absorb agents directly to hair follicles and sebaceous glands, with minoxidil and plasmid DNA as study molecules.

This literature watch compiles recent studies on photobiomodulation therapy across various applications, offering no new empirical findings.

This study found that in people with leprosy sequelae, ulcers on the lower limbs exhibited decreased microbial diversity and reduced abundance of specific bacteria compared to normal skin, with skin metabolites closely linked to these microbial changes.

This study found that among 100 Caucasian patients with androgenetic alopecia, dermatologists could discern hair loss at thresholds significantly lower than the previously cited 50% reduction, highlighting the importance of using objective trichometric measurements to improve detection and personalized treatment strategies.

Light and temperature affect the daily skin function rhythms in hairless rats, with temperature influencing water loss but not skin hydration.

This study found that among vitiligo patients in south-southern Nigeria, there were significant correlations between digit lengths and digit ratio, but further research is needed due to the small sample size.

This study developed and validated an HPLC method for detecting a novel 5α-reductase inhibitor in human plasma, supporting its pharmacokinetic evaluation at low doses.

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

This study successfully isolated inner ear-specific exosomes from perilymph samples of sensorineural hearing loss patients using a novel immunomagnetic approach, enabling groundbreaking liquid biopsy diagnostics.

This study found that applying controlled hypobaric stress to the skin significantly improved the in vitro and in vivo penetration of macromolecules, facilitating enhanced drug delivery.

This study identified compound heterozygous mutations, c.1101del and c.736 T > A, in the LIPH gene responsible for causing autosomal recessive woolly hair in a child, with c.1101del being a novel frameshift mutation.

This study developed a method using ultra-high performance liquid chromatography-mass spectrometry (UHPLC-MRM-IDA-EPI) for the rapid and sensitive detection of 13 JAK inhibitors in anti-alopecia cosmetics, showing excellent separation and accurate quantification with high recovery rates in tested matrices.

Lichen planus may be associated with a higher risk of metabolic syndrome.

This study found that a phytosome lotion made from Mangkokan leaf extract, using a green solvent and microwave-assisted extraction, demonstrated greater hair growth activity than 2% minoxidil, with the 30% phytosome lotion showing the highest efficacy in increasing hair length, weight, and diameter.

This study found that women with female pattern hair loss experienced improvements in hair loss severity and quality of life from low-dose oral minoxidil use, despite a common side effect of unwanted hair growth, which most did not consider a reason to stop treatment.

This study identified a specific LIPH gene mutation (736T>A) as common in Japanese patients with autosomal recessive woolly hair/hypotrichosis, potentially indicating its role in the condition's manifestation within this population.

This study found that the medulla of Japanese hair contains unsaturated lipids such as squalene and oleic acid, which may contribute to hair glossiness.
