I had to leave that product because the synthetic chemicals were irritating my scalp (not a natural product). My favorite is a 100% real Argan Oil, not just a few drops in the bottle. Russell Organics Argan Oil, http://www.russellorganics.com , I have been so happy with it. Very good quality at a very good price. And unlike those synthetic Argan Oils, I can use Russell Organics Argan Oil on my face, body, and nail beds.
