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.
