Unfortunately I have really fine hair, and the ends are very dry and brittle. Some time ago I once had a serum from Kerastase, that really was very very good but also very expensive. When I discovered this at the drugstore, I thought to myself that it indeed has two phases and perhaps similar acts. And indeed, it is at least as good, if not better. My fine brittle ends are very silky maintained without hang down completely overloaded. I've gotten the 3rd bottle and use it every third shampooing.
