A tip I just learned from my amazing hair stylist Candyce is this: store Argan oil in a dark place. She said sunlight will cause it change color. I googled this and found that storage of Argan oil is suggested to be 1 month supply in the bathroom & remaining product in the refrigerator. Now, that may be just pure Argan oil and not the mixed Argan/Moroccan oil products that are so popular these days. However, thought I'd share in case anyone purchases their oil in rather large quantities: protect your oil & extend shelf life by keeping it in a cool & dark place such as the fridge.
