I have very thin hair and this spray gives instant fullness. It works well without needing to wash it out. My hair feels stronger after use and I can style it with heat without damage.

It’s effective for adding volume, especially when I brush my hair in the morning. The formula is light and doesn’t make my hair feel greasy. I use it every day before styling.
