This study found that alkali bromide solutions are absorbed into hair depending on salt activity, and the presence of the salt increases water absorption compared to normal conditions.

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

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 found that nearly all nurses caring for chemotherapy patients showed detectable levels of cyclophosphamide in their urine, indicating significant occupational exposure to this antineoplastic drug.

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.

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 research outlines the characteristics and potential applications of a GMP-compliant sodium polyphosphate formulation (Na-polyP-GMP) in cellular energy storage and ATP-dependent processes like skin regeneration and wound healing.

This notice states that the article has been withdrawn due to the journal's transfer to a new publisher and reports no research findings.

Minoxidil is effective for hair growth and safe for long-term use.

This study demonstrated that modified montmorillonites combined with bacterial cellulose enhanced antimicrobial, wound healing, and tissue regenerative activities in a burn mice model, suggesting potential as an artificial skin substitute for burn patients.

This study identified a sulfotransferase activity in rat liver that catalyzes the sulfation of minoxidil, contributing to its delayed hypotensive effects.

In this study, chitosan glycolate sponges demonstrated the highest cell survival rates and blood absorption, highlighting their potential as hemostatic materials, whereas chitosan ascorbate sponges inhibited cell growth and metabolic activity, indicating further development is needed.

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 that the antioxidant N-acetylcysteine attenuated ferroptosis in the uterus and placenta of a PCOS-like rat model, indicating its potential as a therapeutic strategy for PCOS-related complications.

This study found that a testosterone patch and gel showed bioequivalent testosterone levels in hypogonadal men, but the patch mimicked a natural circadian profile, while the gel resulted in higher dihydrotestosterone levels.

This review discusses the role of glucocorticoids in treating severe inflammatory disorders and highlights their potential adverse effects, recommending dosage management to minimize these risks; no new clinical results are reported.

This review discusses the potential use of spin traps in cosmetic products to limit reactive oxygen species generated by pollution, emphasizing the need for further research due to toxicity and regulatory concerns.

This review discusses home-use laser and light skin devices for various dermatological purposes and reports no new clinical findings; the authors highlight the need for dermatologists to evaluate these devices' clinical value.

This study reviewed the literature on laser and light technologies in dermatology, highlighting their varied clinical applications such as skin rejuvenation, acne scar treatment, and hair removal, alongside their potential for combining with AI to improve outcomes.

New microneedle method improves hair regrowth treatment delivery.

This study found that while nicotinic acid significantly inhibited human sebaceous organoid growth in vitro, the predicted skin concentrations from gut microbiome-derived levels were far below the effective dose, suggesting high oral doses would be necessary for therapeutic effects.

This review found that exposure to pollutants like PM, NOx, and PAHs is linked to various skin and hair disorders, indicating a need for cosmetics with natural adsorbents to reduce pollutant effects, achieving 30-55% removal efficiency.

This study found that caffeine and flufenamic acid penetrated porcine skin more effectively through hair follicles, while the importance of the follicular pathway varied for other substances tested.

This study found that ethosomes containing 30% ethanol slightly improved the targeting of dutasteride to hair follicles in vitro, with a higher targeting factor compared to dried ethosomes and controls after 24 hours on porcine skin.

This study found that human keratinocytes express a sodium-dependent multivitamin transporter for biotin, pantothenic acid, and lipoic acid, including a highly specific biotin transport component.

This review highlights the potential of permeation enhancers to improve the delivery of active ingredients across the skin, optimizing therapeutic outcomes despite challenges posed by individual variability and environmental factors, according to the authors' analysis of current understanding and applications in skincare and transdermal therapies.

This study's simulation found that Ascorbyl Tetraisopalmitate penetrates more efficiently through the skin's stratum corneum than via the infundibulum, following different pathways and dynamics in each membrane.

This review discusses the enhancement of drug penetration through hair follicles and reports no new clinical results while noting the potential for future research on controlled drug release methods.

This study found that feeding mice a high-fat diet with fish oil leads to hair loss through a mechanism involving omega-3 fatty acids and TNF-α signaling, with epidermal fatty acid binding protein playing a key role.
