BACKGROUND: Application of herbal paste and oil to a dog's coat and body before rinsing (often combining with shampooing) is a cosmetic therapy available in Japan. It is highly appreciated by users, who claim that the treatment makes the coat shinier, improves volume and eliminates tangles. However, there has been no scientific evaluation of such treatments. HYPOTHESIS/OBJECTIVES: Improvement of hair condition is derived from oils such as sebum and conditioning oils because chemicals are not used. Therefore, we examined nonpolar lipids (the primary lipids in dog hair) and the botanical oils used in this therapy. ANIMALS: Hair samples were obtained from six beagle dogs. METHODS: Groups were based on different combinations of the following processes: rinsing, shampooing, herbal therapy and herbal therapy with oil extract. Analysis of lipids was performed by high performance thin layer chromatography. RESULTS: The processes of shampooing and herbal therapy were associated with an equivalent reduction in cholesterol ester and triglyceride (TG). However, hair treated by herbal therapy combined with oil extract had an almost three‐fold higher TG content, even after shampooing. CONCLUSIONS AND CLINICAL IMPORTANCE: This study demonstrated that the herbal therapy was able to coat hair samples with TG that was not removed with rinsing. Further investigation is required to evaluate the possible benefits of the application of botanical products containing lipids, such as TG, on hair coat quality in dogs.
