Carbonylation of Hair Proteins: A Robust Biomarker of Molecular and Structural Oxidative Damage in Hair Fibers

research Carbonylation of hair proteins: A robust biomarker of molecular and structural oxidative damage in hair fibres

February 2025 in “International Journal of Cosmetic Science”

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.

research C‐reactive protein promotes adhesion of monocytes to endothelial cells via NADPH oxidase‐mediated oxidative stress

24 citations , January 2012 in “Journal of Cellular Biochemistry”

This study found that C-reactive protein may enhance monocyte adhesion to endothelial cells through NOX-mediated oxidative stress, suggesting a potential mechanism for atherogenesis.

research Particulate matter 2.5 damages skin cells by inducing oxidative stress, subcellular organelle dysfunction, and apoptosis

215 citations , March 2018 in “Archives of Toxicology”

This study found that PM2.5 exposure induced oxidative stress in human keratinocytes and mouse skin, causing cellular damage, which was mitigated by the antioxidant N-acetyl cysteine.

Hair Growth Defects of Diabetic and Hypercholesterolemic Wistar Albino Rats and Amelioration with Fish Oil Treatment

research Hair Growth Defects of Diabetic and Hypercholesterolemic Wistar Albino Rats and Amelioration of Fish Oil-Treatment

January 2015 in “Journal of Nutrition and Health”

This study found that fish oil supplementation in male Wistar albino rats helped maintain hair shaft structure and improved amino acid composition, while reducing harmful protein compounds associated with diabetes and hypercholesterolemia.

Amino Acids, Peptides, And Proteins In Cosmetic Science

research Amino Acids, Peptides, and Proteins

5 citations , January 2017 in “Elsevier eBooks”

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.

community Nandrolone Replacement Therapy

43 upvotes 3 years ago

A user discusses starting nandrolone replacement therapy to stop hair loss and improve hair health, noting its benefits over finasteride. They report halted hair loss, improved skin, increased muscle, and a calm mood after three weeks.

community Protein's role in hair growth is more nuanced than just quantity

in Technology 5 upvotes 4 months ago

Protein's role in hair growth is complex, with specific amino acids like cysteine being crucial for effective hair growth. Users discussed using l-cysteine supplements, noting reduced hair loss and faster growth, though some experienced digestive issues.

community protein powder and creatine ????

11 months ago

Minoxidil is being used for hair loss, and there is concern about whether protein powder or creatine affects hair condition. Creatine is debated, with some users reporting no effect on hair loss, while others suggest it may cause hair thinning in those predisposed to alopecia.

community Derm told me that my whey protein usage is speeding up hair loss?

26 upvotes 4 months ago

Whey protein is unlikely to cause hair loss, and some users suggest it might be beneficial if dietary protein is insufficient. Hair loss is generally considered genetic, and there is skepticism about the dermatologist's advice to switch from whey protein to whole foods.

community Whey Protein can cause hairloss in men with AGA as per a doctor

64 upvotes 8 months ago

Whey protein may slightly increase hair loss in men with androgenetic alopecia (AGA) due to elevated IGF-1 and testosterone levels, but the effect is minimal compared to treatments like finasteride and dutasteride. Many users argue that whey protein's impact on hair loss is negligible and that maintaining a healthy lifestyle is more important.
