This study found that white hair fibers have lower lipid content and different water absorption dynamics compared to brown hair fibers, suggesting differences in their barrier functions.

This study found that bleached hair showed optimal protein structural integrity and tensile strength at pH 5, with significant changes in cross-linking, water content, and diameter at more alkaline or acidic levels.

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 topical fulvestrant did not significantly improve hair growth parameters in men and postmenopausal women with androgenetic alopecia, unlike minoxidil, which was more effective in men.

This literature review suggests that fractional laser therapies may positively impact hair regrowth in androgenic alopecia, though current evidence is mostly limited to small studies and case reports, highlighting a need for more comprehensive randomized controlled trials to confirm their efficacy and safety.

This study concluded that the follicular route is a significant pathway for delivering gentamicin through the skin, as demonstrated by higher drug permeation in non-plugged pig's ear skin compared to plugged skin.

Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.

This study found that L-cystine-modified rabbit hair fibers had improved dye adsorption and spinnability, due to changes in secondary structure and surface characteristics.

This study found that under optimized extraction conditions, the Gleditschia fera fruit extract contained a high level of saponins and demonstrated notable antioxidant activity.

This study observed that DDAIP-HCl enhanced the permeation of minoxidil through human cadaver skin, suggesting potential for improved treatment efficacy in male pattern hair loss.

This study found that paracellular transport significantly contributes to the intestinal permeability of minoxidil, suggesting its limited suitability as a Biopharmaceutics Classification System reference drug due to potential variability.

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.

Targeting drugs to hair follicles can treat skin conditions, but reaching deep follicle areas is hard and needs more research.

In this study, Neeli Bhringadi hair oil showed statistically significant improvements in hair growth rate, density, thickness, and reduction in premature graying on participants with androgenetic alopecia and hair graying over 120 days, supporting its potential use in integrative hair care.

In this study, a liposomal-encapsulated Sesbania grandiflora formulation significantly improved hair and scalp health in adults with hair loss over 180 days, showing enhanced hair density, thickness, growth rate, and tensile strength compared to placebo, with no related adverse events reported.

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.

In this review, recent innovations in hair transplantation, such as AI-assisted graft selection, robotic systems, stem cell therapy, and advanced drug delivery techniques, are reported to enhance hair density and thickness for more natural results and higher patient satisfaction by addressing limitations of traditional methods.

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.

In this study, researchers in Baghdad, Iraq found that men with hair loss had higher body fat mass and haematocrit values, and lower blood pressure compared to men without hair loss, suggesting potential links between metabolic and hematologic changes and baldness.

This systematic review and meta-analysis found that oral minoxidil improved hair loss symptoms in many patients, with significant improvement in 35%, but 27% experienced adverse events, highlighting the need for further research to confirm its safety and efficacy.

This study evaluated emerging techniques for managing chemotherapy-induced alopecia and found that scalp cooling significantly reduced hair loss, while photobiomodulation was well-tolerated without major adverse effects; however, further research is needed to refine treatment protocols and ensure long-term safety.

This case study reported that an 18-year-old woman ingested a large amount of topical minoxidil, leading to symptoms like low blood pressure, increased heart rate, and elevated liver enzymes, but recovered fully after treatment. Minoxidil toxicity may rarely cause abnormal liver enzyme levels.

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 study observed that low levels of calcium and magnesium in blood serum were associated with health issues like hair loss and anxiety among participants from urban and rural Pakistan.

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.

In this literature review, potential health risks of toxic chemicals commonly found in cosmetic products were linked to issues such as cancer, reproductive abnormalities, and skin diseases, highlighting concerns over ingredients like talc, parabens, and phthalates.

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

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 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.
