I love the Giovanni as a leave in. I have not found anything better. I am not crazy about their leave in. However, I dont think I can use the Giovanni every day, so I alternate with the VO5 Shea Cashmere, or Cure Care (Sally). Sometimes I leave just a small amount of these 2 in my hair, like now, when the weather is colder. I dont see the need for a separate leave in.
