This is the best Argan oil I've found. I got a sample of it in a Birchbox and I absolutely loved it. I have long, straight heavily highlighted hair. If that weren't enough, I live in Colorado where the climate is very dry. Needless to say, my hair gets dry and frizzy, especially after blow drying it. All it takes is a pea size amount of this oil to make it all go away! I was skeptical about using that little of the product, but it is so good that a pea size is really all I need. Be sure to use a little at a time so you don't end up with oily looking hair. My hair looks and feels smooth, silky and healthy, and since you need such a small amount, the small bottle will last for a long time...Definitely recommend!
