So lightweight!
Perfect for my thin hair, it doesn’t weight it down or feel greasy. I do still need a heat protector but this really helps the quality of my hair

Amazing product
Really blown away by this! My hair has a tendency to fluff up after blow drying, and one pump of this smoother through the ends appears to have solved the issue. My hair is shiny and manageable until the next wash. Miracle!
