This product is a life changer from the forehead up.
Moroccan Oil has transformed my frizzy, unruly curls into soft, shiny spirals. I'd recommend it for those without curly hair too though. It's does a number on the wallet, but it lasts a long time. (I'm still using the large bottle I bought last summer and I've got a least a few more months to go.)
I've heard that the shampoo is fabulous also. Magazines rave about this brand, and now I suppose I am too.
