How to use the Cast Foam
"I created this because every foam I tried was sticky, heavy or did nothing for wavy hair. I love how lightweight it is, yet it gives me the most gorgeous, defined waves without losing that natural movement. And unlike a mousse, it won’t leave your hair crunchy or overloaded, just soft, bouncy waves that actually hold."
