I don't really know if I think this product is on par with Kerastase's other products, but it is definitely a good product. I, who have very frizzy and wavy hair, think this handled the frizz well. However, you need to keep in mind that it needs to be activated with heat to reach its full potential. It gave a little shine but nothing wow in my opinion. On the other hand, it smells as good as all of their products.
In summary, this probably works well for you with more Scandinavian and lightly frizzy hair. If you have even thinner hair, I think it can work even better just on the shine.
I am participating in a test panel and received a free test product.
