“…Oil extracts from Camellia japonica (camellia oil), coconut oil, red palm oil (extracted from Elaeis guineensis ), avocado oil and other oils are believed to penetrate into human hair strands and are used as ingredients of hair treatments to improve hair gloss. The fatty acid TG is found in botanical oils and a hair conditioning function has been suggested; for example, it has been reported to inhibit water‐induced swelling of damaged hair and is used as a conditioning agent for protection and repair of damaged hair. Treating canine hair with an oil extract may improve hair coat lubrication along with an increase of glossiness; it may also prevent tangling in animals with curly coats such as poodles.…”

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.

“…Kojima, Tsuji [51] studied the penetration of palm oil into the hair fibres using the time‐of‐flight secondary ion mass spectrometry (TOF‐SIMS). Brunelle, Touboul [52] and Saleem and Galla [53] reported that in TOF‐SIMS, the particles, after ionization, are accelerated into a ‘flight tube’.…”

Consumers are attracted to the latest fashion trends and different looks. This drives the search for novel hair treatments. Some chemicals present in hair treatment products can penetrate the hair shaft. These materials can either nourish or injure the hair cortex. Different techniques have been used to investigate the mechanism of molecule penetration and the conditions under which penetration occurs. This article reviews the techniques applied for this purpose. Various microscopy techniques are used to capture clear and colourful images to determine the diffusion pathways and the exact location of the molecules under study. However, the laborious sample preparation often leads to sample destruction since cross‐sectioning is often required. While various other techniques have been successfully used for investigating the penetration methods, most of these require different amounts of work to be put in for sample preparation and instrumentation. Several spectroscopic techniques have been used to study the penetration of the molecules because of the high levels of accuracy and the quick response time of these techniques. Moreover, the samples are not damaged during the investigation.

“…Translucent films dyed at pH 6 exhibited a greater uptake of dye. In other studies, time‐of‐flight secondary ion mass spectrometry (TOF‐SIMS) was used to examine the penetration of hydrogenated palm oil into human hair using a tripalmitin‐d 98 fragment ( m / z 286) . Palm oil was detected in the cuticle and upper cortex of chemically damaged hair fibres.…”

The technology for generating high quality keratin films has recently advanced and led to their implementation in a variety of applications. As an initial step toward investigating the films as a screening tool for predicting the efficacy of potential hair dyes, CI Acid Orange 7 was applied to a set of opaque and translucent films. Overlaid time‐of‐flight secondary ion mass spectrometry images arising from protein and dye fragments revealed that dye uniformly penetrated both film types. Results also showed that the relative concentration of dye in each film complemented outcomes from ultraviolet‐visible analysis and revealed that the translucent film contained a higher dye concentration. Scanning electron microscopy analysis of film morphology suggested that the observed difference was due to the higher porosity of the opaque film, which facilitated dye desorption during the rinsing step. Consequently, the translucent film was judged to be a better substrate for screening potential new hair dyes.
