I think you're right, some argan oils have like you say argan oil on the label but very little amount, I find it's more on the thin side of the oils, saying that I've only used a few argan oils and haven't spent much on each bottle and I've used all sorts of oils throughout the years one I'm loving at the moment is avocado oilSaj what did you like /dislike about the argan oil? I've been curious about it ever since reading a bunch of Fergiebilly's SR SOTDs and was going to get some, except it seems a bit of a minefield whether you get good stuff, not so good stuff, or a hair product that may contain traces of it but has Argan Oil written in the biggest letters on the pack. I ended up going with bio oil instead which I now really like to use after the SR rather than as a pre.
I've come to the conclusion anything more than just a wash with a good glycerin soap like Pears or La Toja Magno doesn't add much, and one time I think it was Proraso green preshave even reacted badly with the shave soap. Can't remember which soap it didn't work with now though, annoyingly.
