This study discovered that a specific G to C mutation in the ornithine aminotransferase gene is linked to the retarded hair growth phenotype in mice and may serve as a model for human gyrate atrophy.

In this study, researchers evaluated the binding of keratin-associated proteins and α-keratins to human hair fibers, finding that chemical preactivation significantly enhanced binding to natural hair, while perming altered binding characteristics and increased penetration depth.

This study found that the count of CAG trinucleotide repeats in the androgen receptor gene may be associated with acne in female patients without hyperandrogenism.

This study suggests that deficiencies in certain amino acids, like taurine and tryptophan, in artificial milk formulas may contribute to skin and eye problems in Bengal tiger cubs.

This review discusses various metabolic and vitamin disorders affecting hair structure, including Menkes' syndrome, arginosuccinicaciduria, and recent findings on vitamin-related alopecia, but reports no new clinical results.

Human hair keratin has a 40% α-helix structure that changes to a random coil in 8 M urea.

Aged skin heals slower due to more inflammation and disrupted cell communication.

This study found that plasma jets can effectively clean and oxidize human hair fibers, with argon/oxygen plasma having the strongest effects, suggesting potential as an alternative to peroxide treatment.

This study discusses the effects of incorporating various amino acids in hair care products, noting improvements in hair surface properties and color retention when integrated with conditioners.

This article reviews popular peptides used in cosmetics for wrinkle treatment and presents no new clinical findings.

This study identified 374 eQTLs in scalp hair follicles associated with genes involved in metabolic, mitotic, immune processes, and responses to steroid hormones, contributing insights into genetic variation and hair traits.

This study found that Synsepalum dulcificum seed oil hair treatment significantly reduced hair breakage and improved hair health indices in women, outperforming both placebo and argan oil treatments.

In this study, dimeric peptide derivatives were shown to enhance the proliferation of human follicle dermal papilla cells in vitro, particularly promoting the ERK1/2 pathway, suggesting potential for developing peptide-based treatments for hair regeneration.

This study suggests that residues Val-889 and Arg-752 in the androgen receptor's steroid binding domain are crucial for NH2-/carboxyl-terminal interaction, affecting receptor stability and function.

This study found that fluconazole increased water transport in renal cells via effects on aquaporin-2 channels, suggesting potential as a treatment for nephrogenic diabetes insipidus, though clinical trials are needed to confirm efficacy in humans.

Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.

This case report documented a family in Prayagraj, Uttar Pradesh, India, suffering from epidemic dropsy due to consuming mustard oil contaminated with argemone oil, resulting in symptoms like pancytopenia, acute kidney injury, and reticular hyperpigmented rash; conservative management showed improvement in their condition.

This review compares nanoemulsion formulas from several plants, such as argan and candlenut oils, which showed enhanced effectiveness in promoting hair growth in animal tests.

This study found that a topical treatment combining arginine and zinc significantly reduced hair loss and increased anagen hair percentage in patients with androgenetic alopecia and telogen effluvium, suggesting it might be a promising alternative to finasteride.

The document concludes that skin and nail changes can indicate various underlying health conditions.

Twisting hair weakens it, but strength can be recovered at low twist levels.

This study found that cysteine and arginine are crucial for hair growth in hair follicles, with cysteine affecting hair fibre diameter and arginine involved in protein incorporation and energy metabolism.

In this study, the combination of low level light therapy with arginine, arterial extract, or biotin tripeptide-1 was associated with improvements in hair density and follicle structure in androgenic alopecia.

This study found that MNX@Arg-CLAVs nanovesicles enhanced hair regeneration and reduced aging in hair follicles in AGA mice, with less skin irritation compared to traditional minoxidil tincture.

In this study on mice, researchers developed CLA-loaded nanovesicles that showed potential anti-aging effects on hair follicles and enhanced hair growth compared to commercial minoxidil, with lower skin irritation, suggesting a promising approach for treating androgenetic alopecia.

This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

In this case series, the researchers reported successful individualized homeopathic treatment for alopecia areata in three patients, with each case receiving a specific remedy—Natrum Muriaticum, Calcarea Carbonica, or Argentum Nitricum—resulting in positive treatment outcomes.

In this study, freezing gamma-irradiated amniotic fluid increased hair follicles and accelerated the transition to the anagen stage in rats, suggesting potential for treating hair loss safely and effectively.

This review synthesizes traditional hair-care practices from diverse cultural regions and evaluates them against scientific evidence, noting that some, like coconut oil application, have clinical support, while others rely mostly on in vitro or theoretical backing.

This review found that hair loss is nearly universal by mid-life, significantly impacts psychological well-being, especially for women, and that users often discontinue the leading treatment, minoxidil, due to adherence issues.
