From this, it does not sound as if hazelnut oil is very penetrating. A barrier means that it sits on top of the skin. On the next page it refers to the oils as being occlusive. That means barrier too. Test strand it on your hair. You can always blott it off. Or, test it on your hands and see how greasy they get. Many things can be called astringent. Again, that comes down to degree. How astringent? What about using less? etc.
