Sep 17, 2012 - This is the absolute best oil I have tried and believe me, I have tried them all. Macadamia, argan, Ojon, and they all contain silicones. My hair likes certain silicones but not the ones they use in these oils. The fabulous thing about the Mongongo Oil is that it contains NO SILICONES! My hair is in love with this stuff. When I went to get some of the new Co-Wash at my local Ouidad salon I saw this oil and decided to buy the 2 oz bottle ($36). Now I am thinking I should have bought the big one (4oz/ $58). I wasn't sure how it was going to work and that's the reason I didn't buy the big one. If it didn't work out I would be left with yet another oil in my arsenal of oils. Thank you Ouidad! I will be buying this oil for many, many years to come!
