Reviews Summary
Customers say this volumizing treatment works especially well for fine and thin hair. Many users notice immediate volume and fullness without heaviness or greasiness. The lightweight formula works best when applied to wet hair before styling. While most experience noticeable results, some report subtle effects. The product leaves hair feeling soft and manageable, with several mentioning it helps maintain style throughout the day. A small number find it makes their hair feel dry or flat.

    love this

    a very good volumizing serum! had a bit of issues with it at first (getting white specks when i used it near the scalp), but not anymore. i scrunch it in my hair before my other serums and creams.
