I use and adore the Moroccan Oil for hair- although I have also wondered about how much silicone is in it. I adore the scent ( it's like MPG Or des Indes!) and also use the Moroccan Oil Curl Cream. Both my younger daughter and I use it- we have thick coarse wavy hair and both look like Krusty the Clown if we don't smooth it with something. It is a LIFESAVER.
I know Kiehls and Josie Maran both have true Argan oils that can be used on hair but again, bet some silicones are *slipped* (LOL) in there somewhere. Although Josie Maran's stuff is supposed to be organic/natural. I tried the Kiehls but think I used too much as my hair looked slicked lol
I will look for your recommendation- my other daughter has fine silky hair but its quite long so she needs to use something on the ends. The Moroccan Oil is way too heavy for her hair.
