In this study, liposome-encapsulated thioglycolic acid improved hair perming by enhancing the penetration of perm solutions, resulting in a stronger S-shaped wave and higher cysteine content compared to the control.

This study found that compound 10 inhibited testosterone conversion to DHT in hamster flank organs and seminal vesicles, whereas compound 11's inhibitory effect varied with dose, linked to halogen electronegativity differences.

Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.

This review discusses the properties and extraction methods of keratins from natural fibers and highlights their promising applications in fields such as biomedicine, bioengineering, and forensic science, but reports no new experimental results.

This study found that the moisture sorption and desorption process can differentiate between cosmetic treatments of hair and provide insights into hair fibre structure changes, with bleaching causing greater symmetry breaking than perming.

This study found that in healthy adult women, a collagen and antioxidant-rich treatment significantly improved skin elasticity, hydration, texture, and reduced wrinkles and hair fall over 56 days compared to a placebo, indicating its efficacy and safety.

In this study, the researchers developed a hydrogel mimicking the fetal environment that significantly accelerated wound healing and hair follicle regeneration in vivo, with over 94% wound closure in 14 days, surpassing hydrogels lacking certain additives.

This study investigated chitosan–hydroxyapatite biocomposites, finding them to enhance anti-inflammatory cytokine expression, support cellular activities, and reduce pro-inflammatory cytokines in a dermatitis model, while highlighting gaps in understanding their immune modulation and issues with reproducibility for clinical use.

This study found that a chitosan-based hydrogel containing silver nanoparticles and ibuprofen demonstrated strong antibacterial activity and accelerated wound healing in vivo, suggesting its potential use in wound dressings.

This study highlights the potential of chitosan nanoparticles to improve cannabidiol solubility and delivery for treating alopecia, suggesting a promising approach for transdermal delivery of hydrophobic compounds.

This review highlights the use of microneedling devices and patches to deliver cosmetic agents through the skin, noting their applications in skin rejuvenation and safety considerations such as potential skin irritation and infection.

The new chitosan dressing heals wounds better and faster than current products.

This study found that MCS nanoparticles improved Minoxidil's hair growth effects in an animal model compared to the commercial formulation, but they were less effective than CS nanoparticles despite showing better solubility with minimal side effects.

This study found that shampoo and conditioner do not alter hair's molecular structure, while perming treatments significantly affect keratin and intermediate filament structures due to bond alterations.

Alopecia areata's causes are unclear, treatments exist but relapses are common.

This review identifies cysteine's central role in hair growth and its potential impact on Alopecia Areata's pathogenesis, suggesting examination of cysteine metabolism might clarify the disease's underlying mechanisms and lead to new treatments.

This study constructed a model to predict finasteride's inhibitory activity on 5α-reductase type 2 and calculated that a 1 μM plasma concentration, after 50 mg administration, matches prostate inhibition levels.

This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.

This research elucidates the molecular mechanisms underlying carbamazepine and griseofulvin's inclusion complex channel formations with polymers, revealing why carbamazepine forms stable channels independently, while griseofulvin requires polymeric support due to weaker interactions.

This study found that co-applying Curcuma aeruginosa extract or essential oil with minoxidil significantly increased minoxidil's skin penetration in an ex vivo setting, suggesting an improved topical treatment strategy for androgenic alopecia with greater efficacy and the potential for lower minoxidil doses.

This study found that permanent waving treatment induces structural changes in the cortex proteins of white human hair, significantly reducing its tensile strength without altering the S-S band intensity.

Allopregnanolone likely doesn't influence ethanol's rewarding effects in these mice.

This review provides an in-depth analysis of the structure and function of c-kit activation, and its role in both normal physiological and pathological conditions, with no new research findings reported.

This study found that octahydrobenzo[c]quinolizin-3-one derivatives, particularly compound 3, were potent and selective inhibitors of the enzyme 5α-reductase type 1.

This review suggests that although hydrolyzed collagen peptides with certain supplements may improve skin elasticity and joint function, evidence for collagen's anti-aging and regenerative benefits remains inconsistent.

This study found that the methanolic heartwood extract of Avicennia marina significantly inhibits 5α-reductase type 1, reducing 5α-DHT production by 52% in a cell-based assay with human hair dermal papilla cells.

This study found that Caesalpinia bonduc seed extracts significantly reduced prostate weight and improved prostate tissue morphology in Wistar rats with testosterone-induced benign prostatic hyperplasia.

In this study, researchers using network pharmacology and molecular docking methods found that compounds from Avicennia Marina could inhibit hepatitis C virus infection by targeting key proteins such as AKT1 and TNF-α, showing potential for anti-HCV treatments.

This study's simulations suggest that replenishing free 18‐MEA could restore damaged hair surface properties, highlighting the importance of optimal fatty acid spacing for maintaining hair integrity.

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.
