In this study, fraction No. 3 of Oryza sativa bran extract demonstrated high unsaturated fatty acid content and significant 5α-reductase inhibition, suggesting potential for developing anti-androgenic alopecia products.

This study found that Datura metel extracts obtained through supercritical CO2 extraction demonstrated significant biological activity, including antioxidant and anti-inflammatory properties, and effectively promoted wound closure and collagen preservation, comparable to standard treatments, in laboratory experiments.

In this study, the proposed MSF-VMDNet, combining dual encoder networks with a multi-frequency domain mechanism, significantly outperformed existing methods in segmenting skin cancer tissues from histological slide images, achieving high accuracy with an MIoU of 95.37% and a Dice coefficient of 95.11%.

In this study, porcine collagen acellular dermal matrix scaffolds combined with mice platelet-rich plasma were associated with increased hair density and follicle regeneration in mice with alopecia, suggesting a potential therapeutic approach.

This study observed that surfactants in cosmetic treatments can bind to keratinous tissues like hair and nails, affecting their tensile properties and possibly leading to deterioration depending on the specific detergents used.

This study found that higher melanin concentration in black hair offers photoprotection against sunlight-induced protein damage in the cortex, whereas the cuticle experiences similar photodamage regardless of hair pigmentation.

This study found that extensive cuticle damage from diperisophthalic acid oxidation did not alter the tensile properties of human hair, suggesting that these properties are mainly due to the cortex rather than the cuticle.

This study found that repeated cycles of wetting and blow-drying hair fibers can cause cracks in the hair cuticles, particularly among individuals who frequently blow-dry their hair.

This study found that hydrolyzed wheat proteins extensively penetrated both untreated and chemically treated hair, primarily occupying areas like the endocuticle and cortex.

This study discusses that permanent hair straightening can be achieved at neutral or acidic pH conditions, with varying effects on cystine and lanthionine levels, by inducing supercontraction of the hair fiber.

This study found that high concentrations of dimethyl sulfoxide are needed to cause significant swelling in hair fibers, though the swelling is reversible, unlike the effects on skin.

This study found that using a high-viscosity, high-amine-content silicone fluid as a pretreatment can protect hair from bleaching and dyeing damage without affecting these processes.

This study found that spironolactone at doses of 75 or 100 mg per day did not improve hair density after six months in women with female pattern hair loss, suggesting that higher doses may be necessary.

This study found that dimethicone with high molecular weight improved hair surface characteristics, while dimethicone copolyol and amodimethicone enhanced manageability by reducing friction or aiding styling on damaged hair.

This study found that among 120 men, two antidandruff shampoos increased sebum excretion rate, while one shampoo decreased sebum output, highlighting distinct effects on the follicular reservoir.

In this study, topical dehydroepiandrosterone (DHEA) doubled sebum production in women without systemic side effects, suggesting it may be a safe treatment for reduced sebum output related to menopause.

This study found that hair treatments applied after chlorination, especially bleaching and dyeing, more significantly altered surface properties and weight loss, while perming most strongly affected tensile properties.

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

This study found that anti-keratin antibody from immunized cow milk increases the resistance of damaged hair to stretching and inhibits fracture from excessive brushing.

This study found no conclusive evidence of biocatalytic activity of guinea pig liver transglutaminase with virgin human hair, potentially due to a fatty acid layer on the hair surface.

This narrative review discusses the discovery of plasticity in epidermal stem cells using single-cell transcriptomics, but reports no new results; it highlights the potential implications for regenerative medicine.

This study identified a cluster of genes on chromosome 17 related to hair keratin-associated proteins, including 37 genes forming seven multigene families, localized in the hair shaft's upper cortex.

This study observed that in aged mouse skin, there was an increase in IL-17-expressing T helper cells, γδ T cells, and innate lymphoid cells, and blocking IL-17 signaling reduced skin inflammation and delayed age-related changes, suggesting it as a potential target to mitigate skin aging.

In this study, rice bran supercritical CO2 extract demonstrated potential to promote hair growth in mice, increasing hair follicles and growth factor expression, similarly to 3% minoxidil.

This study suggests that gel containing OSF3 loaded in niosomes offers high transfollicular penetration for topical anti-androgenic alopecia treatment with minimal systemic effect.
