I use products from Moroccanoil both in the form of shampoo and conditioner, but also their treatment oil. It has a combination of argan oil and vitamins amongst other things. Besides what miracles it does to my hair, it smells like heaven!
"Argan oil is a plant oil produced from the kernels of the argan tree (Argania spinosa L.) that is endemic to Morocco. In Morocco, argan oil is used to dip bread in at breakfast or to drizzle on couscous or pasta. It is also used for cosmetic purposes." - https://en.wikipedia.org/wiki/Argan_oil
