I have always been so scared of using products (let alone OIL!) on my hair, and having baby-fine hair encouraged me even less. My hair stylist insisted that he try it on my hair (for free, since I was so reluctant) and I was SO impressed! It left little to no weight difference, my hair was shinier and more flexible looking. Thanks to my hair stylist for convincing me, as this stuff is EXPENSIVE. Probably worth it if you spend that kind of money on your appearance already, but worth the money, though.
