Hi Charley I have found argan (Moroccan) oil to be extremely useful. I bought Moroccanoil which is a commercial brand packed with silicone (boo ooh! still, it does the job), but if you are looking for organic argan oil there's some websites in the answers to my question about organic argan oil I asked a few days ago, otherwise I've also found a supplier on Amazon which works out slightly cheaper, see sources below.
