Mythic Oil and Extraordinary Oil both by L'Oreal are fantastic on my hair, I prefer them to Argan oil. It's a bit trial and error as to which one suits you. The Argan oil I used last year was £30 in my salon and on Amazon it was a tenner so worth having a quick google ime.
I use the Maca oil and I like it. I have very dry big wavy hair ( attractive eh?). I find it works best if I leave my hair for about 10-15 mins after washing it before putting it on my hair. For some reason it makes my hair more shiny and silky that way.
I have the Argan oil but I don't think it is as good.
