Polymethylene wax in hair relaxers makes hair smooth and shiny with less damage.

Twisting hair weakens it, but strength can be recovered at low twist levels.

A new method helps understand hair shine and various products improve hair care.

This study found that a new SIS-PEG sponge promoted rapid skin defect healing in mice and showed potential for reconstructing reconstituted skin with regenerated hair.

This study found that Na CMC hydrogel loaded with PEG-coated silver nanoparticles demonstrated superior antibacterial and wound-healing efficacy compared to commercial silver sulfadiazine cream in a wound-healing model.

This review surveys the chemical composition and various uses of jojoba oil in medicine and industry but presents no new clinical results.

This study introduced a novel nonsteroidal androgen receptor antagonist that effectively controls sebum production in the golden Syrian hamster ear model through targeted follicular delivery.

Diphenyl ethers can potentially reduce excess oil production when applied on the skin, helping treat conditions like acne.

This study found that formulating raloxifene in nano-lipid carriers significantly enhanced its permeation and cytotoxicity against cancer cells compared to raw raloxifene.

In this study, researchers developed microcapsules and effervescent tablets containing policosanol from insect wax, achieving high encapsulation efficiency and rapid water dispersion, effectively addressing the challenges of solubility and psychological acceptance in consuming insect-based lipids.

This study found that in semi-coarse wool sheep of the Ukrainian Carpathian Mountain breed, changes in microflora and grease composition are linked to increased felting in wool, due to wetter, more alkaline fleece conditions that promote bacterial and mold growth and alter fatty acid balances.

This study found that laccase-assisted grafting of poly(tyrosine) onto wool materials improved shrinkage resistance and mechanical properties while causing minor decreases in crystallinity and thermal resistance, suggesting a potential "green" approach to enhance wool durability.

This case report describes a 65-year-old man diagnosed with atraumatic splenic rupture, which is rare and can occur without trauma, following sudden-onset left-sided abdominal pain.

This study confirmed that the novel solid lipid microparticle formulation of adapalene demonstrated follicular penetration potential and targeted particle erosion in sebum in in vitro tests.

The document says biodegradable cosmetics and packaging are better for the environment and user experience.

This study demonstrated that hair follicles significantly expedite the absorption of caffeine through the skin compared to interfollicular pathways.

This article reviews the development and formulation of shampoos, emphasizing their dual role as cosmetic and medicinal products, but presents no new experimental findings.

This study reports that C3H/HeJ mice and DEBR rats serve as effective models for screening potential treatments for human alopecia areata, despite certain challenges in predictability and cost.

This article reviews innovations in hair cosmetics, focusing on esthetic procedures and products in the Indian market, and reports no new experimental findings.

This study found that adapalene-loaded solid lipid microparticles may enhance targeted drug delivery into sebum due to their similarity to sebum components, although both this formulation and a standard cream showed equivalent follicular penetration.

This review explores the use of skin penetration enhancers like Transcutol® in various formulation systems, discussing their mechanisms and effectiveness in improving transdermal drug delivery without breaching the skin.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

This study reports that 4-(alkylthio)- and 4-(arylthio)-benzonitriles showed moderate sebum reduction as androgen receptor antagonists when applied topically in a validated animal model.

This study found that using nanoporous silica entrapped lipid-drug complexes enhanced the solubility and bioavailability of dutasteride in beagle dogs.

This case report indicates that contact dermatitis on the face can result from using a bleaching ointment containing ammonium bisulfite during hair-dyeing.

Pulsed dye laser and hydrogel dressings effectively treat hypertrophic scars.

This review highlights that castor oil has potential dermatological uses, including enhancing hair luster, reducing hyperpigmentation, and improving skin hydration and elasticity, although rare side effects like contact dermatitis occur, necessitating further research to confirm its effectiveness in these applications.

The letters discussed medical tools, costs, treatment efficacy, and patient care complexities.

This study found that bioconjugating 16-methylheptadecanoic acid (16-MHA) to damaged hair can mimic the protective properties of 18-methyleicosanoic acid (18-MEA), restoring the hair's structural integrity and moisture homeostasis, even after washing.

Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.
