This study found that coconut oil impedes hair hydration more effectively than soybean oil by penetrating deeper, and suggested a new model for intermediate filament assembly in hair.

This study found that moisture sorption properties of wool and hair fibers from various animals were similar, despite different structural features, with sorbed water being more ordered than liquid water.

This study found that topically administered spironolactone in healthy volunteers resulted in no detectable systemic absorption or changes in related hormone levels over 72 hours, indicating local effect only.

This review outlines the histological structures of the skin, highlighting species and regional differences in dermal absorption and obstacles encountered in toxicological assessments due to epidermal thickness variability, contact dermatitis reactions, and stem cell vulnerabilities.

This study investigated the penetration of a low-molecular-weight cationic conditioning compound into the hair cortex and suggests it may improve hair's fatigue resistance.

This review reported that while glycyl-L-histidyl-L-lysine tripeptide copper complex (GHK–Cu) has limited skin permeation when used alone, liposomes may enhance its absorption, but there is limited research on this aspect, highlighting a need for further studies.

This study found petroleum ether to be more effective than methanol at extracting β-sitosterol from Eclipta alba, with higher concentrations detected using HPTLC and HPLC methods. The extracted materials contained metals within safety limits.

In this study, the researchers developed and optimized a curcumin nanocrystal gel to enhance skin permeability, reporting improved dissolution properties and antiproliferative effects on cell lines, suggesting it as a promising topical delivery system.

This review reports that innovative topical treatments for dermatologic conditions like acne and atopic dermatitis show minimal systemic absorption, indicating improved safety and tolerability compared to traditional therapies.

This study found that hair treated with a supplemental hair care product showed significantly higher absorption, deeper penetration, and reduced dryness compared to untreated and water-treated hair, as measured with 3D Raman spectroscopy.

This case report highlights that improper application techniques, such as scalp occlusion, can increase systemic absorption of minoxidil and lead to unwanted side effects like hypertrichosis.

This review suggests that combining nanotechnology with herbal components in hair cosmetics may improve the delivery and effectiveness of treatments for issues like damage, dandruff, and hair loss.

This study found that overexpression of the SbbHLH85 gene in sweet sorghum increases root hair growth and Na+ absorption, but negatively affects salt tolerance.

This notice states that the article has been withdrawn due to the journal's transfer to a new publisher and reports no research findings.

This research letter observed that patients with severe atopic dermatitis showed normal serum cortisol levels after hospitalization despite continued use of potent topical corticosteroids, though poor adherence may lead to overestimations of actual medication use.

Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.

This study used theoretical calculations to show that phosphates strongly bind to cerium dioxide surfaces in various stable configurations, with spectral signatures identifiable in the infrared and Raman spectra, informing future experimental efforts in controlling the enzymatic activity of ceria nanoparticles.

This study identified differentially expressed proteins and pathways potentially involved in wool bending in Zhongwei goats, with specific genes like COL6A1 and CRNN emerging as important candidates in this process.

This review explores the effectiveness of Murdha Tailam methods, particularly in Panchakarma treatments, for illnesses related to the head and neck, highlighting the advantage of scalp drug absorption due to anatomical features that facilitate treatment outcomes.

This paper discusses advancements in forensic hair analysis, emphasizing a novel DART–HRMS method that improves the accuracy and efficiency of detecting drug use timelines.

This study developed the TLMG hydrogel, a seamless in situ biointerface platform, demonstrating robust adhesion, high conductivity, and therapeutic effects for intelligent wound management in complex animal models and human tests, indicating its promise for integrated bioelectronic medicine.

This study found that antiandrogenic pretreatment with combined oral contraceptives did not improve ovulation and pregnancy outcomes compared to direct letrozole induction in women with PCOS.

This study found that Fibroblast growth factor-9 (FGF-9) accelerates epithelial invagination in engineered ectodermal organs and suggests its potential role in organogenesis and regeneration research.

This review discusses the role of jasmonic acid and its conjugates in enhancing plant stress tolerance and balancing growth and defense mechanisms but provides no new experimental data.

This article discusses the potential health risks associated with long-term use of finasteride and dutasteride for prostate and hair loss treatments, suggesting risks may include non-alcoholic fatty liver disease, insulin resistance, type 2 diabetes, and other metabolic issues.

This study found that the topical Shen Bai hair growing decoction may improve androgenetic alopecia in mice by suppressing TNF-α and IL-6 levels, enhancing follicle density, and reducing apoptosis.

The study reported that a poly herbal gel containing Lagenaria siceraria, Trichosanthis cucumarina, and Tridax procumbens promoted hair growth in human volunteers, with noticeable effects observed after 90 days.

This study found that Finasteride may spontaneously diffuse into an SDS-based model cell membrane at a significant rate, with distinct behavior in polar and non-polar solutions.

This study reported that among obese women with PCOS, neither early time-restricted eating (eTRE) alone nor combined with probiotics showed significant improvements in blood pressure, inflammatory markers, oxidative stress, or antioxidant capacity compared to a standard reduced-calorie diet.
