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 discarded squid ink was used to develop a high-performance, environmentally friendly hair dye that offers a stable deep black color, UV protection, and preserves hair structure, while showing excellent biosafety in lab tests.

This study found that untargeted hair metabolomics analysis detected significantly altered endogenous biomolecules, potentially serving as biomarkers for identifying oxidative cosmetic hair treatments like bleaching.

The authors concluded that while PRP is a promising and well-tolerated treatment for early to moderate knee osteoarthritis, standardizing preparation protocols, patient selection, and outcome reporting is crucial to enhance comparability and inform clinical practice.

This study reports that Broussonetia papyrifera extract significantly increased hair count over 12 weeks in a small clinical trial and promoted dermal papilla cell proliferation in vitro by regulating WNT-β-catenin and STAT6 pathways.

This research observed that chronological age, rather than hearing loss, primarily affects the auditory cortex in aging, and found that brain aging in PolG mice mirrored that of wild-type counterparts, suggesting differential tissue sensitivity to mitochondrial dysfunction.

This article outlines methods to study the skin and its molecular traits, focusing on interpretation and techniques applicable to mouse models, including diverse assays and approaches like electron microscopy and large-scale lipid analyses.

This study explored how alopecia impacts the socio-emotional lives and daily adaptation of women, finding that while not life-threatening, alopecia initially affects how they adjust to daily routines and perceive social and partner relationships.

This study suggests that while some evidence indicates potential efficacy of placental products for hair growth and inhibiting hair loss, the current scientific evidence is scarce and of low quality.

In this study, a hair tonic containing fragrant pandan leaf extract and virgin coconut oil was formulated and evaluated, with most variations demonstrating physical stability except for one formulation, which showed instability in the specific gravity test.

In this case study, an 11-year-old girl with a Cladosporium scalp infection showed significant improvement in hair growth and appearance after treatment with itraconazole.

This case study reports that a 9-year-old Nepalese boy with tinea capitis successfully recovered with systemic antifungal therapy, though experienced focal alopecia without recurrence at a two-year follow-up.

This study reported a simple and validated gas chromatography method to accurately measure finasteride in tablets, showing equivalency to the official method with no significant differences.

This document outlines recommendations from an international panel on testosterone therapy for aging men with late-onset hypogonadism, emphasizing the need for careful assessment and monitoring due to limited long-term safety data.

This study found that exosomes derived from platelet-rich plasma show preclinical promise for wound healing but lack sufficient data for other dermatological uses like hair growth and skin rejuvenation.

PRP injections can increase hair density in people with androgenic alopecia.

This review reports that tinea capitis is uncommon in adults, with postmenopausal African American or Black women at higher risk, and emphasizes the importance of prompt antifungal treatment to prevent complications.

This review highlights the need for improved methods in cosmetic safety assessment, emphasizing the potential of engineered skin tissue for more effective detection and toxicological evaluation of cosmetic products, compared to traditional methods.

This study developed a simple and cost-effective chromatographic method for simultaneously analyzing betamethasone dipropionate and calcipotriol, achieving rapid separation within 7 minutes suitable for routine applications.

This study found that hair cortisol concentration is a promising stress indicator in cattle but not in pigs, where external factors and lower cortisol response may interfere with its validity.

This study found that progesterone levels were higher and increased significantly throughout pregnancy, contrasting with stable levels in non-pregnant women.

This study found that ATR-FTIR spectroscopy combined with machine learning effectively differentiated alopecia areata patients from healthy controls with an AUC of 0.85, and also showed promise in predicting treatment response, particularly through alterations in the Amide I band.

This review discusses various methods for processing and separating human skin samples for research purposes, evaluating factors like processing time and cell viability, but reports no new experimental findings.

This study investigated 130 patients and found a significant inverse correlation between copper content and the copper/zinc ratio in hair samples and the extent of coronary artery disease, while zinc content alone showed no significant relationship with disease extent.

Homemade hair treatments can significantly lower drug levels in hair, possibly causing false-negative drug tests.

This review concluded that the double-spin PRP preparation method may be more effective than the single-spin technique for treating androgenetic alopecia.

This study found that intra-follicular Wnt signaling and dermal BMP signaling oscillate differently during hair cycling in mice, affecting hair wave propagation and phases of hair growth.

This review discusses different preparation and application methods of platelet-rich plasma in dental regenerative medicine and reports no new results, highlighting its potential and associated controversies.

This study demonstrated a method for large-scale preparation of self-sorted hair follicle germs in vitro, which successfully generated hair follicles when transplanted into the skin of nude mice.
