Argan oil is unlike any other oil I have EVER used. I buy (pure) from camdengrey.com- they have the best prices I have found.
Argan makes my hair feel like butter! I like the cheapy ones with cones just as much as the pure oil. They both have a place in my reggie.
I use Sally's one and only for heat styling.
I add the pure one to my DC's.
I made an oil blend for sealing that is a combo of: Pure Argan, Sally's Argan and JBCO- this mixture is divine.
Also, it is GREAT if you have dry scalp, Argan is the first oil that actually seems to moisturize - which is strange, because I know oils do not.
Argan is also GREAT on dry skin.
I have not been impressed with many of the Argan oil "conditioners" out there. I have tried CON, Moroccan Oil and DermORganics.
My favorite Argan oil conditioner is Lustrasilks Organic Conditioner. The ingredients are: water(aqua),stearmidopopyl,dimethylamine,stearyl alcohol,cetyl alcohol,argania spinosa kernel oil,carrot(daucus carota sativa) seed oil,rosemary (rosmarinus officinalis) leaf oil,juglans nigra (black walnut) leaf extract, cholesterol,aloe vera(aloe barbadensis extract,chamomilla recruita extract, indian hemp extract,fragrance,vitamin e, methyl & propyl paraben,phosphoric acid,dmdm,disodium edta,yellow 5 &6.
Do a search, I have found that people either love or hate this particular Lustrasilk Cholesterol, my hair LOVES it, lol.
But again- buy some pure Argan Oil and you can make your favorite conditioner an "Argan Oil" conditioner at a fraction of the price.
ETA: I have just bought the One n Only Restoravtive Mask, but I have yet to try it.
