My last hairpiece was made in Germany and consisted of 60% fiber and 40% human hair. The care -products for it are from there too. One is a conditioner which has ``Organic silicon oil`` in it. You use it sparingly and it`s a leave - in conditioner. I found it good for achieving the ``Shine``you are looking for. You may be able to get it from them directly. Just do a search for Arcos hair design germany --- I had a quick look at the site --- it appears you have to create an identity and log on fully before you can contact them, but I hope that helps ----- I can post a pic of the product here if you wish --just let me know. It seems to be mainly for fiber units, but it must be ok for natural hair as there is real hair integrated into my old unit and it never did any harm to it.
