If you apply it all over your head, the hair gets oily immediately. It requires a very small amount for the ends. It smooths the hair, but that's about it!

The consistency is quite thick and a small amount is enough. Although the product bottle says it's for the whole hair from root to tip, I find it quite heavy and prefer to apply it from the middle to the ends. It nourishes and hydrates the hair. However, I remove one star due to the strange unpleasant smell. I don't know if natural keratin generally smells like this.
