May 1996 in “Journal of Investigative Dermatology” The study investigated the role of ornithine decarboxylase (ODC) in hair follicle function using transgenic mice that overexpressed a mutated ODC transgene in hair follicle keratinocytes. These mice experienced normal initial hair growth but lost their hair completely 2-3 weeks after birth, coinciding with the onset of ODC overexpression and the development of follicular cysts. The study found that the ODC inhibitor 2-difluoromethylornithine could prevent hair loss and partially restore normal skin histology if administered early, and it could also reactivate hair growth in mice with complete hair loss. The results suggested that ODC played a crucial regulatory role in mouse hair follicles.

April 2010 in “International Journal of Cosmetic Science” 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.
