This study developed a liquid chromatography with tandem mass spectrometry method to detect sex hormones in health supplements from Hanoi, Vietnam, finding three out of 16 samples contained sex hormones, including banned testosterone at low levels (~0.5 mg/kg).

In this study, a novel electrochemical sensor using a molecularly imprinted polymer was developed for the sensitive detection of minoxidil, successfully measuring its concentration in real samples.

This review discusses the use of platelet-rich plasma for facial rejuvenation, acne scarring, and androgenic alopecia and reports positive outcomes but emphasizes the need for standardized preparation and application methods.

This study concluded that low-level fluence 810 nm diode laser therapy was generally well tolerated, safe, and effective for long-term hair reduction in a small sample of patients with various skin types.

This study developed a new method for detecting 30 hormones in anti-aging functional foods, demonstrating good sensitivity and reliability, and identified seven hormones in four out of 14 samples tested.

This study observed that storing hair follicle micrografts significantly decreased the expression of certain key genes in the dermal papilla, potentially affecting hair follicle cycling during preparation and storage.

This review suggests that PRF may be a promising alternative treatment for oral mucosal lesions, but further research is needed to confirm its long-term effectiveness and standardize preparation protocols.

In this laboratory study, researchers developed a multifunctional organic hair cream with various natural extracts, finding that the cream with 15% extracts demonstrated higher physical stability, hair strength, and antimicrobial activity compared to lower concentration samples and synthetic alternatives.

This study found that using a formulated herbal hair oil, which includes ingredients like Nigella sativa and Cocos nucifera, reduced hair fall progressively over periods ranging from 15 to 90 days among 25 volunteers, showing greater efficacy than simple purified coconut oil.

This review examines the efficacy of platelet-rich plasma for treating hair loss, highlighting the lack of standardized protocols for PRP preparation and delivery and reporting no new clinical results.

This study developed a validated HPLC method for accurately estimating dutasteride and its related compounds in capsules, suitable for routine and stability sample analysis.

This review examines recent advancements in analytical techniques used to quantify dutasteride, a medication for enlarged prostate, in various biological samples and its commercial forms, emphasizing methods such as HPTLC, GC-MS, and HPLC.

This study demonstrated that a 3D air–liquid culture system using Wnt-CM-treated cells can induce hair regeneration in nude mice and may facilitate large-scale preparation for hair loss treatment.

This review highlights the potential of nanoemulgel as a promising drug delivery system for lipophilic drugs, but presents no new experimental results; it discusses composition, preparation methods, and applications.

This study observed that noncertified Kohl used in Iranian cities contained heavy metals within WHO suggested limits, but highlighted concerns due to high levels in some samples.

This research reports that onychomycosis, a common nail fungal infection often caused by Candida yeast, requires laboratory testing like direct preparations, fungal cultures, and molecular tests for accurate diagnosis due to its diverse etiology and differential diagnosis, improving therapy effectiveness and efficiency.

This review highlights the potential of extracellular vesicles derived from medicinal plants as therapeutics for diseases such as cancer and inflammation, suggesting they may enhance the clinical use of herbal preparations, despite the challenges posed by extract complexity and individual variability.

This study found that varying the concentration of propylene glycol in katuk leaf extract hair tonic formulations significantly affects the viscosity, highlighting the importance of propylene glycol concentration in maintaining the physical characteristics of these preparations.

This research focused on formulating finasteride, dutasteride, and minoxidil with cyclodextrins to enhance their solubility and skin penetration for topical use, potentially reducing scalp irritation from current alcohol-based preparations.

The study suggests that variability in platelet-derived growth factors in PRP is influenced by both patient-to-patient differences and the devices used for PRP preparation, contributing to inconsistent clinical outcomes in hair loss treatments.

In this study, multimedia education significantly improved the knowledge and practices of women with polycystic ovarian syndrome, particularly in managing symptoms like menstrual irregularity and oligomenorrhea, as observed in a sample from the Sohag University Hospital clinic in Egypt.

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 observed that prolonged water or soil exposure can lead to significant reductions in drug levels in bleached and natural hair samples.

This study found that among natural hair loss treatments, formulations with Cantharidin in the saponifiable fraction showed superior efficacy compared to those with Pilocarpine.

This study demonstrates that bacteria contribute to hair follicle neogenesis after skin wounding through IL-1R1 signaling in keratinocytes.

This study identified trilauric glyceride and decanoylcarnitine as potential biomarkers for diagnosing PCOS in patients with and without insulin resistance, suggesting significant metabolic alterations in these conditions.

This study developed a method for extracting proteins from micro-sized human head hairs, facilitating proteomic analysis even with limited hair sample availability.

Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.

This study developed a simple method to determine finasteride, indapamide, and tiemonium methylsulfate in pharmaceuticals by using their ability to form silver nanoparticles measurable via spectrophotometry.

This study found that hair samples from children with kwashiorkor or marasmic kwashiorkor had about 20% less cystine compared to one child with adequate protein nutrition, suggesting the need for further research.
