ABSTRACT=For pets, healthy hair not only represents their beautiful appearance, but also reflects their overall health status. Nutritional imbalance, skin parasites, and stress can all cause a large amount of hair loss in pets, leading to skin-related diseases and posing a threat to their health. So, it is very important to understand and find solutions to alleviate or treat pet hair loss. The Wnt/β-catenin signal plays a core role in the hair regeneration process. Here, we report that keratin hydrolyzed, egg yolk lecithin, and fish collagen peptide promote β-catenin nuclear translocation and significantly enhance the expression of their target genes in canines and cats skin cell lines, indicating that these nutrients are likely to play a beneficial role in promoting hair regeneration in canines and cats.
