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.

The EFSA panel concluded that coriander seed oil is safe for use as a novel food ingredient at the proposed intake levels for healthy adults.

This study investigated lipid loss in hair caused by surfactants and found that surface and internal modifications can significantly protect different lipids from depletion, with internal modification preventing 52.0 to 81.3% of lipids in certain groups.

This article discusses diagnostic and treatment options for excessive hair growth in women, noting a need for holistic approaches to address associated psychological issues, but it does not present new clinical findings.

This study found that higher concentrations of copper (II) ions in human hair increase protein oxidative modification, contributing to hair damage regardless of UV exposure and pigmentation level.

This study found that electrophoretic keratin typing of head hair can identify specific polypeptide patterns, suggesting potential applications in genetic and forensic investigations.

This article discusses the benefits of liposomes in cosmetic formulations, including enhanced hydration and protection for dry skin, but reports no new experimental findings.

This study demonstrated that the biomimetic peptide PTP20 may help preserve hair pigmentation and reduce greying by enhancing melanocyte function and increasing melanin production in human hair follicles.

This article reviews various aspects of shampoos, including preparation methods and commercial value, but reports no new experimental results, instead focusing on patents and product evaluation criteria.

This study found that in Japanese, German, and American females, changes in hair lipid patterns with age may reflect alterations in sebum excretion and affect hair texture.

This review highlights the potential of nanoemulgel as a promising drug delivery system for lipophilic drugs, but presents no new experimental results; it discusses composition, preparation methods, and applications.

This study reported that the pseudoceramide bis-oleamido isopropyl alcohol (BOI) promotes hair growth in ex vivo cultured human hair follicles, likely by enhancing sphingolipid synthesis in dermal papilla cells.

This study found that hydrogenated palm oil effectively conditions damaged hair by preventing water-induced swelling, with TOF-SIMS analysis showing that its component tripalmitin penetrates the hair's cuticle and outer cortex.

This study found that Celsr1, not Celsr2, is the primary protein involved in establishing planar cell polarity and hair follicle polarization in the epidermis of mice.

This study found that the medulla of Japanese hair contains unsaturated lipids such as squalene and oleic acid, which may contribute to hair glossiness.

This study developed a new proteomic method to identify and assess ancient hair proteins using only small amounts of sample, providing insights into hair protein alteration processes over time.

This review summarizes the antioxidant and anticarcinogenic properties of Indian Gooseberry, its phytochemical composition, and its use in traditional Ayurvedic medicine, but reports no new clinical results.

This article discusses primary cutaneous virilism, focusing on alopecia in women with androgen-dependent skin conditions, and reports no new findings.

This review focuses on the roles of amino acids, peptides, and proteins in cosmetics, highlighting their importance in skin health and their potential for development in personal care products due to their unique properties and biocompatibility.

This review discusses techniques and models for assessing hair growth activity but reports no new clinical findings, emphasizing the need for standardization and improved animal models.

This study found that hair analysis is an effective non-invasive method for assessing metabolic fluctuations, showing stable advanced glycation end products levels that correlate with age and differ significantly between diabetic and non-diabetic rats.

This study found that a hydro-alcoholic extract of Roselle petals may reduce free radical production during UV-induced photodecomposition of antibiotics, potentially offering protective benefits for patients using similar topical antibiotics.
