Palmarosa is one of the best essential oils around and I would urge you to try that conditioner. If you are sensitive to evening primrose oil, use black currant oil as a substitute.
Palmarosa is like the poor man's version of sandalwood. I say poor man's only because sandalwood is so expensive. Palmarosa is one of the richest essential oils I think I have used and is excellent in terms of price. A friend of mine gave me a 2oz bottle for Xmas two years ago (NOW Foods brand) and I haven't used half of it. It's very concentrated. Just to add to what you have written: It is excellent for deterring split ends and in terms of regeneration, it is highly reparative to the scalp. Just as a rule of thumb, if you see an essential which is reparative to the skin, remember that your scalp is skin, too /images/graemlins/laugh.gif

P.S. The smell is lovely..sort of a musky rose, but better than that description. Mixes well with any of the citrus essentials and enhances ones like vetivert (substitute for sandalwood), frankincense, etc.
