Nothing amazing for fine hair!

If you have fine or thin hair like me that's prone to oiliness, PLEASE STAY AWAY from this product! It made my freshly washed hair look greasy even though I barely used a nickel-sized amount of product. That being said, if you just want to use it for one day and wash the next, then go for it but don't use a lot of the product. It does work for me when I'm straightening my curly hair, in getting a smoother sleek look. The serum smells pretty good and applies better to damp hair instead of dry hair. I've done both and just need to make sure that I rub the product between my hands really well before I apply to my hair because it has a tendency to clump together and not distribute easily on dry hair.
