This study describes a method to extract and characterize keratin particles from human hair, finding they can encapsulate the anticancer drug Paclitaxel with significant efficiency, releasing it in a pH-dependent manner potentially beneficial for targeted cancer treatment.

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 reported that dandelion herb-derived carbon dots significantly enhanced wound healing in mice with Staphylococcus aureus infections, outperforming a commercial wound healing spray through their antibacterial and dual ROS-modulating capabilities.

In this study, carbon dots derived from dandelion herb demonstrated significant antibacterial and biofilm-disrupting capabilities, promoting wound healing in a mouse model infected with S. aureus, while also showing excellent biocompatibility and the ability to modulate reactive oxygen species.

This review discusses the role of melanin synthesis in melanoma, focusing on how melanosomal pH might regulate melanin production, and reports no new results.

This study observed that patients with alopecia areata had significantly lower serum 25-hydroxyvitamin D levels than healthy controls, with a trend toward even lower levels in more severe cases.

This systematic review reported that among men taking finasteride for benign prostatic hyperplasia, total PSA levels decreased by 30% to 50%, and free PSA by up to 45%, with reductions in prostate volume and PSA density observed as well.

This study found that oral probiotic supplementation over 12 weeks may improve hair growth, skin condition, metabolic health, and stress responses in Chinese adults with hair loss and a high risk of metabolic syndrome.

This article reviews recent imaging and genetic tool advances that enable in vivo study of hair regeneration and assessment of skin parameters, but it reports no new clinical results.

This study reviews the complex keratinization process in the epidermis, detailing how various factors regulate keratinocyte differentiation and emphasizing the importance of understanding this process for the pathogenesis of skin disorders like ichthyoses and psoriasis.

This study formulated and evaluated the physical stability of hair tonic preparations using lime extract (Citrus aurantifolia) at varying concentrations. The researchers found that the tonics exhibited good physical stability, as indicated by meeting Indonesian National Standards, even after undergoing temperature cycling tests.

This study investigated the physical stability of hair tonic formulations made from ethanol extract of cayenne pepper leaves, finding that formulations with specific concentrations of propylene glycol and ethanol had good physical stability.

This article discusses isotretinoin for severe acne vulgaris, noting its effectiveness but also highlighting significant side effects on skin, mucous membranes, and hair; it reports no new clinical results.

This review discusses gender-linked skin differences, such as hormone metabolism and sebum production, and reports no new findings; it suggests these insights might inform male-specific dermatological treatments or cosmetic products.

This review discusses the roles of metabolism, reactive oxygen species, intracellular pH, and cell morphology in influencing cell fate decisions during stem cell differentiation but reports no new experimental results.

This study developed a straightforward HPTLC method for detecting nicotine and cotinine in human plasma and urine, concluding that liquid-liquid extraction with methanol: chloroform: ammonia achieved optimal separation and is applicable for forensic analysis of lethal nicotine intoxication.

In this study, researchers analyzed a herbal shampoo containing Momordica charantia extract and Hibiscus Rosa-Sinensis, noting it could support collagen development and hair growth. The shampoo, tailored to various hair and scalp conditions, was confirmed free of certain harmful heavy metals.

This study found that finasteride is stable under various stress conditions except for basic hydrolysis at extreme pH levels and identified compatible and incompatible excipients in pharmaceutical formulations, suggesting formulation changes for increased safety.

This study suggests that minoxidil may serve as a suitable reference drug for high permeability classification in the Biopharmaceutics Classification System due to its consistent permeability across different intestinal segments and pH levels.

This study found that a shampoo containing quaternized wheat protein hydrolysate can effectively improve hair recovery by smoothing and compacting damaged hair surfaces, thanks to modifications that enhance protein adherence and disulfide bond formation at pH levels typical in hair care products.

This study describes the development of a herbal oil formulated to promote hair growth, incorporating various herbs such as Murraya koenigii and Panax ginseng, and assesses its properties including viscosity and pH levels.

This study concluded that adding polymeric conditioning actives to shampoos improved color retention in permanently dyed hair, while additional cationic dyes at certain pH levels weakly dyed the hair directly.
