research Adhesion Failure of External Hair Cuticles Caused by Prussian Blue: Possible Electrochemical Roles of Sulfur and Cystine
Prussian Blue causes hair cuticles to detach, weakening the hair.
research Characterization of a First Domain of Human High Glycine-Tyrosine and High Sulfur Keratin-Associated Protein Genes on Chromosome 21q22.1
Researchers mapped and categorized specific keratin-associated protein genes on human chromosome 21q22.1.
research Chronological Aging of Human Hair Keratin Fibers
The study examined very long human hair (over 2.4 m) to understand the natural ageing process of hair keratin fibers using various evaluation methods. It focused on hair that had not been exposed to chemical treatments like bleaching or dyeing. The findings showed that ageing begins with the abrasion of the cuticle while the cortex remains intact up to about 1 m from the root, maintaining shine, hydrophobicity, and friction characteristics. Beyond this point, significant cuticle damage occurs, correlating with a decline in ceramides, 18-Methyl Eicosanoic Acid (18-MEA), and keratin-associated proteins, leading to a decrease in mechanical and optical properties. This research provided a detailed 'damage scale' of hair ageing, which could aid in developing targeted hair care products.
research Asian Hair: A Review of Structures, Properties, and Distinctive Disorders
Asian hair is generally straight and thick, with unique disorders and properties, and more research is needed to understand it fully.
research Prostanoid Receptors in Anagen Human Hair Follicles
Human hair follicles contain a complex network of prostanoid receptors that may influence hair growth.
research Characterization of the Cysteine-Rich Calcium-Binding S100A3 Protein from Human Hair Cuticles

research Hair Follicle Miniaturization in a Woolly Hair Nevus
The boy with woolly hair nevus had thinner hair and abnormal hair follicles, which improved with treatment but worsened when treatment stopped.
research Runx1 Transcription Factor Is Involved in the Regulation of KAP5 Gene Expression in Human Hair Follicles
Runx1 helps control the KAP5 gene in human hair follicles.
research Hair Shaft Abnormalities: Pili Bifurcati - A Scanning Electron Microscopy Analysis
The study found that pili bifurcati causes hair to intermittently split into two branches, each with its own outer layer.
research Topically Applied Glycyrrhizic Acid Causes Hair Removal in Rats
The study investigated the effects of topically applied glycyrrhizic acid, derived from sweet licorice, on hair removal in Wistar rats. A solution containing 15% glycyrrhizic acid was applied twice daily, resulting in 20-30% hair removal after 3 days and 90-95% after 6-12 days. Long-term treatment over 9 months showed no inflammation and reduced hair regrowth by about 20%. Scanning electron microscopy indicated a smoothed hair cuticle, aiding hair shaft detachment. The findings suggested glycyrrhizic acid as a potential treatment for hypertrichosis in humans.
research Comparison of Damage to Human Hair Fibers Caused by Monoethanolamine- and Ammonia-Based Hair Colorants
Monoethanolamine-based hair colorants can cause more damage to hair than ammonia-based ones.
