This study developed and validated a comprehensive method using mass spectrometry to profile sex (pro)hormones in plasma, with results showing reliable calibration and detection of 31 analytes in samples from pre- and postmenopausal women and men, while addressing potential over- or underestimations in analyte concentrations.

This study suggests that both age and photoexposure may decrease maximum viable epidermis thickness and impact the dermal-epidermal junction in women with Fitzpatrick skin types II-III.

This study found that Follicular Maps, derived from trichoscopic images, remained consistent over time and unaffected by hair cycling or noncicatricial alopecia, offering a precise tool for diagnosing and monitoring hair and scalp conditions.

This study found that females with androgenic alopecia experienced greater improvements in hair density after cosmetic treatments compared to males, in a cohort stratified by age and gender.

This study found that a hair tonic increased hair growth and reduced resting hair ratios in men with alopecia.

In this study, researchers found that massively parallel sequencing of mitochondrial DNA (mtDNA) can improve information recovery from forensic samples, with successful full region amplification possible from as few as 2,000 mtDNA copies, albeit with variability in heteroplasmy among hair samples from the same donor.

This study reported that methanolic extracts of Capparis decidua fruits showed significant in vitro thrombolytic activity, suggesting their potential as a dietary health supplement for preventing thrombotic cardiovascular diseases.

In this study, researchers evaluated deep learning methods for diagnosing Alopecia Areata and found that a modified Inception-Resnet-v2 model achieved a high validation accuracy of 97.94% and loss of 10.4%, suggesting it as an effective tool for classifying alopecia-affected hair.

This study found that scalp thickness and hair follicle depth were reduced in individuals with androgenetic alopecia, and MRI signal intensity was higher compared to those without the condition.

Automated image analysis helps diagnose and monitor alopecia areata by efficiently measuring hair follicles.

This study found that objective measurements of hair growth, such as hair growth rate and diameter, can provide a more accurate evaluation of androgenic alopecia than subjective grading alone.

In this observational study, hair density was found to vary with age, as measured in subjects from a dermatology outpatient department, with males showing a mean unit density of 104.78 and females 108.36.

This study developed a quantitative method using SDS-PAGE and MALDI-TOF mass spectroscopy to accurately determine animal species from hair fibers, validated against standard samples and optical microscopy.

In this study, commercial synthetic braiding hair samples from Kenya were analyzed, revealing that while no Ammonium Thioglycolate was detected, significant formaldehyde contamination was present, with varying concentrations throughout the hair strands, potentially impacting consumer safety.

This review outlines the use of quantitative imaging techniques in monitoring tendon response to platelet-rich plasma treatment for chronic tendinopathy and reports that these methods may aid in tailoring PRP protocols.

This study reports that women with hair loss had significantly lower levels of several biomarkers, including hemoglobin, iron, copper, selenium, vitamin D, vitamin B12, folate, and thyroid hormones, compared to healthy controls.

In this study, the researchers developed a chromatographic method to determine α-tocopherol and α-tocopheryl acetate in pharmaceutical capsules with high accuracy and repeatability, establishing it as a reliable alternative for analyzing these compounds.

This case report suggests that individualized homeopathic therapy with Carcinosin may benefit pediatric patients with alopecia areata by improving hair regrowth and psychological symptoms, as supported by standardized assessment tools.

This study identified three new genetic loci linked to sweat gland density in a GWAS involving 6,210 Han Chinese individuals, highlighting potential targets for understanding conditions like anhidrosis and hyperhidrosis and emphasizing the use of quantitative traits in genetic dermatology research.

Measuring the variety in hair thickness can help diagnose male pattern baldness in Korean men.

This study established an animal model using UV-irradiated C57BL/6 mice to assess hair luster, reporting that UV exposure alters keratin-associated protein gene expression, and suggested potential for developing effective hair care products by evaluating treatments like oral minoxidil.

This study surveyed UK patients who experienced adverse events from Botulinum Toxin for cosmetic purposes, finding 79% reported issues like long-lasting anxiety, and highlighting low awareness of regulatory bodies and reporting structures.

This study aimed to identify new quantitative geometric and mechanical parameters for curly and kinky hair using various microscopy and mechanical analysis methods, revealing correlations between hair fiber geometry and mechanical performance to enhance personal care product development and promote cultural inclusion.

A new image-based method improves accuracy in measuring hair loss in mice.

This study identified numerous nutraceutical components in unripe fruits of three Musa species, potentially valuable for developing pharmaceuticals that promote human health.

This study found that quantitative trichoscopy is a simple and effective method for determining hair density and thickness in Egyptians, establishing baseline values for clinical hair loss investigations.

QMSI effectively maps and quantifies drug distribution in skin tissues.

This study found that Quantitative Mass Spectrometry Imaging offers precise localization and quantification of active compounds in skin tissues, demonstrating benefits over traditional LC-MS in drug penetration studies.
