CNPF is a liquid product. I haven't used it since I went CG, but it can be added to conditioners and deep protein treatments, as well as stylers (gels, mousses) to increase or add protein. Some even use it as part of a spray. Many here like it.

CNPF is fairly potent as far as protein content, so go easy at first. If you're adding it to a product, just add a few drops, and add it to what you're using that day, not the whole bottle. (Adding it to the entire bottle could mess up the preservative and cause the product to go bad). If you need more, you can always increase what you use. Better to need more than having to rehab crunchy /straw-like, overproteined hair.
