Sorry, that's Colorful Neutral Protein Filler from Sally's. It's a clear liquid protein that is meant for use in doing color. I use it for several things, tho - add it to condish, LI, FSG, protein treatments, refresher spray, etc. But my hair LOVES protein. If your hair does not you may want to stick to adding it to color, or putting it in your hair before coloring, if you prefer.
Glad the cut went well!!
