This study found that low-molecular-weight hyaluronate significantly improved the mechanical strength and elastic modulus of overbleached hair by enhancing hydrogen bond networks within keratin.

In this study, researchers found that using 0.75% aspartic acid as an intermediate agent for a permanent wave improved wave formation and retention compared to a control in virgin hair, also reducing cuticle damage and maintaining tensile strength.

In this study, researchers developed a regression model that reasonably predicts consumer-perceived hair breakage using various parameters such as hair smoothness, detangling forces, extensional strength, and hair density among Indian women.

This review discusses the similarities between wound healing and embryonic development, focusing on signaling pathways and their potential for developing new wound healing strategies, and reports no new clinical results.

Ingrown hairs are a common feature in scarring alopecias due to follicular damage.

The SAFE System may reduce hair transplant transection rates but has been critiqued for not being as minimally invasive as claimed.

In this study, wearing a frozen glove during docetaxel chemotherapy reduced nail problems in patients' gloved hands compared to unprotected hands, with onycholysis absent among protected hands.

This study found that Eucommia ulmoides bark extract shows potential antioxidant and hair follicle-support properties in vitro and in vivo, but further validation is needed to confirm these effects.

In this study, a polyphenol and biotin supplement improved skin roughness and significantly reduced hair shedding, but did not demonstrate clear superiority over placebo in overall skin outcomes.

This study found that biotinoyl tripeptide-1-loaded solid lipid nanoparticles significantly improved thermal protection in hair, enhancing cuticle integrity and resistance to heat damage, compared to control samples.

This review highlights that exosomes from adipose-derived stem cells, particularly those enriched with circ-Ash1l, can inhibit ferroptosis and reduce UVB-induced skin aging by delivering GPX4-promoting signals to damaged cells, thus offering a potential regenerative therapy for photoaged skin.

This case report describes how a 23-year-old woman experienced eyebrow thinning and hair loss linked to cosmetic use, with diagnostic tests confirming follicular damage. Discontinuing the product led to eyebrow regrowth, highlighting potential risks from cosmetics and the value of non-invasive diagnostics for evaluation.

This review highlights that practicing Shiroabhyang, an Ayurvedic scalp massage technique using essential oils, may enhance blood circulation, provide nourishment, and improve hair quality by repairing damage and enhancing texture in hair.

This study reported that albino Wistar rats exposed to chemical hair straighteners showed significant hair fiber damage and scalp skin deterioration, which worsened with repeated and prolonged application, highlighting the cytotoxic potential of these products and potential systemic risks.

In this study, the researchers observed that ferulic acid and resveratrol effectively protected chemically treated hair from oxidative damage, particularly against protein loss and color degradation, but not cisteine oxydation prevention, and these antioxidants also offered protection against sun-induced damage when used in conditioners.

In this study, the authors reviewed various herbal ingredients used in hair care products and found that components like aloe vera, hibiscus, amla, and fenugreek have traditional and scientifically validated benefits for addressing hair issues such as hair loss, dandruff, and damage.

This review supports iron deficiency anemia as a valid cause of chronic generalized pruritus and suggests potential mechanisms by which iron deficiency may lead to pruritus, but reports no new clinical results.

This review examines the role of androgens and androgen receptors in regulating glucose and lipid metabolism, focusing on their effects on mitochondrial content and function; it also discusses the sex-dimorphic influence of androgens and provides theoretical insights into their mechanisms.

In this study, the researchers formulated an herbal shampoo and found it exhibited excellent cleansing properties and foam stability, comparable to commercial shampoos, suggesting it as a safe and cost-effective alternative to marketed formulations.

This study found that the loss of papillary fibroblasts in the skin due to UV radiation is mainly caused by an uncontrolled inflammatory response, with T cells helping fibroblast survival.

This study found that UV radiation-induced fibroblast depletion in the skin is primarily due to a deregulated inflammatory response, with T cells aiding fibroblast survival under stress.

This article reviews the potential hair-protective effects of Onion and Aloe vera against damage from hair dyes but reports no new experimental results.

This study found that scanning electron microscopy revealed significant hair shaft changes in women using straighteners, but not in those using hair dye, suggesting its utility in assessing chemical treatment effects on hair.

This chapter discusses the role of orthognathic surgeons in facial feminization surgery, focusing on procedures such as forehead reduction and orbital rim contouring, but reports no new clinical results.

In this study, aspartame consumption during gestation in rats was associated with significant histological changes and increased apoptosis in the skin of their neonatal pups.

Facelift surgery has evolved to focus on natural results and safety, with patient selection and postoperative care being key to success.

Hair health is influenced by genetics, aging, and environmental factors, with proper care needed to maintain it.

Skin changes throughout life, from development before birth to aging effects like wrinkles, influenced by both genetics and environment.

Environmental, chemical, mechanical, and personal health factors can all damage hair and contribute to hair loss or changes in hair quality.

This article shares the authors' experiences with the erbium YAG laser in hair restoration surgery, noting improved graft yield and reduced thermal damage compared to traditional methods.
