The 100% Argan oil intense. But I frequently put a drop of it into my shampoo, then in my conditioner in the shower. It doesn't make my hair heavy or limp. It rinses out clean and leaves my hair soft, with a shine I like. It's potent.
If you find that this shampoo/conditioner is a little too rich, maybe you could dilute them with water? I know hair dressers who swear by this stuff, even for ladies with fine hair.
