Könnte man evtl. gleich noch mit Bier hinterher spühlen?

So ist es. Ich empfehle eine Testreihe druchzuführen. Bei mir hat es ergeben, dass Olivenöl, Kokosöl, Mandelöl, Avocadoöl und Monoi gerne auf das trockene Haar angewendet werden wollen, wohingegen Distelöl und Jojobaöl auf trockenem Haar keine "weich-flausche-Wirkung" sondern einen "klatsche-matsche-Effekt" hatten, wohingegen sie auf fechtem Haar gut gewirkt haben.Yasha hat geschrieben:Manche Haare mögen das Öl trocken einfach lieber.
Mapping penetration of cosmetic compounds into hair fibers using time-of-flight secondary ion mass spectrometry (TOF-SIMS) - ABSTRACT:This difference in results could arise from the composition of each of these oils. Coconut oil, being a triglyceride of lauric acid (principal fatty acid), has a high affinity for hair proteins and, because of its low molecular weight and straight linear chain, is able to penetrate inside the hair shaft. Mineral oil, being a hydrocarbon, has no affinity for proteins and therefore is not able to penetrate and yield better results. In the case of sunflower oil, although it is a triglyceride of linoleic acid, because of its bulky structure due to the presence of double bonds, it does not penetrate the fiber, consequently resulting in no favorable impact on protein loss.
Jetzt müsste man eigentlich "nur noch" die Ölsäurenzusammensetzung und die Molekularstruktur von diversen Ölen kennen und könnte dann die idealen Haarpflegeöle bestimmen.In this communication, penetration of vegetable oils into hair fibers has been investigated by the TOF-SIMS (Time-Of-Flight Secondary Ion Mass Spectrometry) method. In earlier work [1], the method was found suitable to study the penetration of coconut and mineral oils into human hair. Therefore, the study has been extended to a group of vegetable oils with different types of unsaturation in the fatty acid components. Different patterns of penetration have been observed for oils of different molecular structure. The general pattern which emerges from this study is that polyunsaturated oils do not penetrate at all, or do so only sparingly into the structure of hair. Most of these molecules seem to penetrate only into the cuticular region of the hair fiber. Oils with polyunsaturated fatty acids seem to have difficulty in penetrating hair. It is possible that these molecules do not fit into the fiber's cell membrane complexes, which are known to be the diffusion pathways in the keratin fiber. On the other hand, monounsaturated oils, such as olive oil, with more compact molecular structure seem to penetrate readily into the hair fiber.
